4 Most Common Forms of Asphalt Distress

Your driveway will go through a lot of changes from the time it’s new to the day you have to replace it. Each stage requires a different plan of action and the list below will help steer you in the right direction.

Stage 1: Preventative Maintenance

For the first few years, your driveway will only need preventative maintenance, sealcoating and crack filling every other year. Your driveway will stay in Stage 1 for as long as the cracks are not interconnected (alligatoring) and are not accompanied by settlement. Find a good local Sealcoater that will provide a written estimate.

Stage 2: Surface or Base Defects 

Your driveway has entered Stage 2 when sealcoating and crack filling alone will not take care of the problem areas. The driveway may have settled at the garage or curb (very common) or developed spider/alligator cracking or potholes. At this point, you’ll need an asphalt repair to get your surface back in shape. Call an asphalt repair company that can either perform infrared repair or saw cut and remove repairs. Then every other year sealcoating and crack filling regimen mentioned in stage 1 should continue throughout stage 2.

Stage 3: Replacement or Resurfacing 

When 20% or more of your driveway is in poor condition, it’s probably time for a new surface. At this point, repairs are no longer a cost-effective alternative. If you find yourself saying my driveway has potholes, cracking or settlement all over, it’s time to start over with a new driveway. Call a paving contractor and ask them whether you need complete removal and replacement or if resurfacing over your existing surface may be an option. There are certain circumstances that can make a case for repairing a driveway that’s in very bad shape. You may not have budgeted for a new driveway, but have some areas that can’t wait. In that case, just repair the very worst areas to get you by until a new driveway is in the budget.

A typical driveway will last 10-15 years, but this can vary due to the quality of the initial installation, poor drainage, ground movement, and proper maintenance. The key is to find quality contractors that will recommend the right process for your driveway’s condition, regardless of whether they provide that service or not.

How to Know When to Seal Coat or Repave Asphalt Pavements

What is the most cost-effective resurfacing solution after repairing cracks, potholes and depressions in asphalt driveways and parking lots

By Jeff Lax

When it comes to old, worn asphalt driveways and parking lots, commercial real estate owners, property managers, and even owners of single-family homes struggle with the same questions: Do we repave or sealcoat after making repairs to cracks, potholes, and depressions? What is the most cost-effective and durable solution?

The industry has debated this issue for decades, and what has been learned is that each option has lasting, dramatic effects and that they actually complement one another. That’s the information pavement maintenance contractors need to convey to their clients who are trying to decide which pavement maintenance option best suits their needs and property.

Sealing

Sealcoating is one of the most important steps to protecting an owner’s investment in an asphalt driveway or parking lot. Sealers consist of emulsions that combine asphalt or refined coal tar with clays, mineral fillers, and water. Once applied, the water evaporates and the emulsion hardens to form a protective coating. It also becomes a beautiful black surface that adds curb appeal, giving a single-family home, multi-family residence, or commercial or industrial property a polished look. Industry experts agree that driveways or parking lots lacking the sealer can generally last only five to six years before the beginning stages of breakdown.

Initial sealing should occur six to 12 months after the asphalt surface is laid to allow the pavement to “cure” so oils can escape and the surface becomes ready for sealer. The initial sealer application forms a barrier to prevent water penetration and to inhibit deterioration of the asphalt binder by oxidation and over-drying.

As unprotected pavement ages, the asphalt binder hardens, losing flexibility and becoming increasingly brittle. Ultraviolet rays from the sun break down the carbon bonds in asphalt, further weakening the pavement. Also, daily and seasonal cycles of heating and cooling cause the pavement to expand and contract. These stresses eventually exceed the pavement’s ability to flex, and cracks form. If water seeps into the cracks and freezes, the cracks expand, allowing more water to penetrate, making the cracks wider and deeper. This cycle leads to accelerated deterioration of the parking lot surface. Early sealcoating can prevent all these preliminary dangers to the life of the asphalt.

Sealer is typically the most cost-effective solution and should be reapplied every two to three years as preventative maintenance. In fact, several government and Asphalt Institute studies have shown that neglected asphalt pavement can cost up to five times as much to repair as asphalt that has had a regular maintenance program, including sealcoating.

Pavement maintenance begins by filling cracks, patching deteriorated areas, and cleaning (and possibly priming) oil-saturated spots on the pavement surface. The asphalt also must be cleaned of dirt and debris before sealer can be applied.

While some homeowners sealcoat their driveways themselves, professional contractors not only apply a high-quality sealer material but also have professional equipment such as crack cleaners and power blowers that often enable them to perform a longer-lasting, high-quality job. Plus, professional contractors can handle other pavement repairs that a homeowner won’t be aware of, so property managers at any level will be best served by hiring a pavement maintenance professional to handle their pavement.

Repaving

Repaving is the only decision for driveways or parking lots that have severe deterioration, deep wide cracks, subsided depressions and numerous potholes.

An asphalt overlay consists of a compacted layer of one-and-a-half to two inches of hot mix asphalt being placed over the existing asphalt, essentially giving the driveway a new surface. Just as with sealcoating, the first task is repair of existing pavement. Areas, where the pavement surface has slumped, indicate failure of the stone foundation supporting the pavement. These areas require digging out existing asphalt, and repair and compaction of the stone base with new material before patching with asphalt mix to prevent trouble spots from returning after repaving. Then an overlay is placed over the old surface. No sealcoating should be added for six months to a year, just as with any newly constructed pavement.

And while an asphalt overlay can begin to deteriorate within five to six years without maintenance, it could last up to 25 years with regular upkeep. The upside to installing an overlay is the pavement has a renewed wearing course, providing a pliable, flexible surface. Also after the overlay, the maintenance program can start over, leading to a virtually brand new drive or lot. However, extreme weather, heavy loads, and shortcuts during construction could lead to premature wear and failure. The downside of repaving is that it is expensive (typically thousands of dollars more than sealing). Plus, if the original asphalt isn’t properly cleaned and prepared, cracks and uneven sections may return, as well as other problems that may not have previously existed such as delamination of the overlay because of poor adhesion to the old pavement.

What’s Better for your customer?

The amount and regularity of repaving will differ from climate to climate, and even when asphalt is maintained properly an asphalt overlay will be needed every 20 to 25 years.

Regardless of whether you repave or repair, sealcoating is one of the most important aspects of any pavement maintenance effort as it protects asphalt from weathering and degradation and extends pavement life. Without sealer, the asphalt could require an overlay in as little as five to six years, costing thousands of dollars. When comparing costs, industry experts believe the best investment a homeowner or commercial property owner can make is a well-tailored maintenance program that includes regular sealcoating.

All of the Benefits of Sealcoating Asphalt Pavement

Here's why that driveway sealer project shouldn't be at the bottom of your to-do list.

For new homeowners who aren't familiar, sealcoat (or pavement sealer) is a liquid coating mixture that's usually applied to asphalt-based pavement. When moving into your new house, fixing the driveway might not be high on your list of priorities. In fact, you might even be asking yourself: Is sealcoating really necessary for my home?

If you’ve made an investment by purchasing a house, you want to take great care of it, right? You spend hours picking the perfect colors to match your sheets, and every Sunday you bring out the vacuum to suck dirt and debris. You might even spend money trimming your trees and bushes to keep them looking lovely.

When you think about it, your driveway takes up much of your front yard. A cracked, dirty, and faded driveway just doesn’t match with clean, polished cars. Here are some reasons why you should invest in a sealcoat for your driveway.

1. Maintain its Appearance
Your driveway takes up space. It’s where cars are parked and where children play during the sweltering summer months. If it isn’t well-maintained, it can have a detrimental effect on your house’s appearance. Asphalt driveways are prone to cracking, fading, and other signs of distress. It doesn’t look good to anyone! Cracks in the asphalt can even lead to accidents.

A sealcoat sits on top of a driveway and acts as a barrier for it. Its deep black color looks regal and strong. The coat prevents water, car fluids, water, the sun, salt, and other chemicals from warping the color or eating away at the driveway. And a sealcoat will prevent weeds from growing in the asphalt. That means no more getting down on hands and knees just to clean those irritating weeds!

New sealcoat, when applied, looks bold and dark. It improves the appearance of both new and old asphalt, adding a pop of vibrancy to your house that you may not have expected.

2. Prevent Cracks
Sometimes, your new home comes with cracks in the pavement. You might be inclined to think, “Well, the previous owner seemed just fine with these cracks. The driveway looks good enough.” Don’t settle for mediocrity—you deserve the best!

Water that seeps into the base material can cause small cracks to widen. Sealcoating your driveway properly will prevent that. Any minor cracks and rough patches can be smoothed over, and if there's any dirt on your driveway, the rain can easily wash it away. That's because sealcoat is a non-porous, smooth surface.

3. Protect the Asphalt
The sun can burn our skin, but did you know it can also harm your driveway? Surface voids on asphalt can absorb oxygen and UV rays. The radiation from the sun can warp the asphalt and cause the color to fade quickly. On top of that, pockets of surface void allow oil or gas to penetrate.

Chemical spills can also worsen your driveway's condition. With a thick layer of sealcoat, you'll be able to prevent (or at the very least, minimize) the harmful effects of spills and the sun. By lowering the rate of water absorption (the water will run right off), sealcoating minimizes the risks of damage due to water, snow, and freezing. There are many things that can destroy your driveway: gas, diesel fuel, salt, chemicals, oil, and ice. It's better to prevent these from attacking your driveway so that you won't have to risk costly damage control.

4. It's Strong
Sealcoat helps attract heat from sunlight and becomes more pliable when hot. Instead of the asphalt cracking at high temperatures, the sealcoat will mold to shape. If you have guests over, the asphalt won’t waver under the combined weight of the cars. That’s because the sealcoat will be there to protect it.

5. It Saves Money
Sealcoating can be done as a weekend DIY project, or you can hire someone to do it for you. A DIY sealcoat project should cost about $50 to $200. It all depends on the size of your driveway. On the other hand, hiring a professional is probably safer. It would cost about $200 to $500. If you choose to hire a company or a person, you can be assured that they'll be more familiar with good products. Different products work better in certain areas (because of the temperature and climate), and a professional will know which sealants are best avoided.

Whether you choose to do it yourself or hire someone else, sealcoating your driveway is far cheaper than spending hundreds of dollars trying to repair or even replace your driveway's asphalt!

If you allow moisture to seep into the driveway, you might not notice at first. But after weeks, the quickened deterioration will begin to show as your asphalt becomes more and more distressed. It’s much easier to prevent the issues instead of scrambling to find someone who can quickly fix the asphalt! Just make sure that you wait 90 days after setting a new asphalt driveway to apply the sealcoat.

Fire Lane and ADA Striping

When your parking lot needs to be compliant with the ADA (Americans with Disabilities Act) Standards of Accessible Design, there are a few things to keep in mind. To begin with, when you need to provide spaces for parking, you have an immediate obligation to remove any barriers to accessibility that may exist in your facility of parking. It is relatively inexpensive to do ADA striping and thus, quite achievable. Here are a few tips to ensure you get it right the first time.

Tip #1: Know Your Number

In each garage or parking lot, the minimum number of spaces accessible is based on the provided number of parking spaces. In every six spaces that are accessible, at least one needs to be accessible by van.

It is always a good idea to perform routine maintenance and repaint your parking lot every one to three years. Signage and striping is required and you need to meet the fire code and striping regulations of ADA.

Tip#1: Follow Your Own State's Parking Requirements

Restrictions of parking according to ADA requirements are mandated by the state. In other words, you will need to inquire about the ADA requirements that are specific to your own state. On the other hand, poorly marked No Parking Areas are a universal issue. Also, many drivers are aware and still decide to illegally park. State laws restrict parking areas for the purpose of public safety. After all, emergency personnel never wants to deal with limited access due to parking illegally.

Tip#3: Fire Lane Signs

If you own a building or a business, ADA requires that you display signs that indicate a fire lane in order to maintain a lane designated for first responders or fire trucks that they can use during a situation of emergency. These types of urgent situations can include fire extinguishing or even another type of emergency.

A fire lane that has a no parking sign indicates that all drivers and patrons of your business must not park in an area designated as a Fire Lane. In addition, in times when parking is not easy to come by, none of the cars ought to park blocking these fire lanes, as they must be kept free at all time. Often, these types of signage are also a requirement by your local government to ensure the protection and compliance of every public establishment.

Tip#4 Striping Your Spaces

When striping your parking spaces, you need to provide ADA-required parking space access. This means there must be a removal of every barrier that barricades access to existing parking lots. It is stipulated by ADA that parking spaces that lead to a specific building needs to be built in the shortest route accessible from the parking point until the entrance.

Tip#5 Size Matters

When striping your parking lot, size does matter. ADA has size specifications that you need to follow. For example, accessible parking spaces need to be a minimum of eight feet wide and should have an access aisle adjacent to this. When it comes to parking spaces for vans, an eight-foot adjacent aisle is required. If striping spaces for cars, there needs to be a five-foot wide access aisle adjacently placed to the parking space. Use the highest quality paint to assure the brightest lines possible.

Why Roads are Made of Asphalt

Britannica:

Asphalt, black or brown petroleum-like material that has a consistency varying from viscous liquid to glassy solid. It is obtained either as a residue from the distillation of petroleum or from natural deposits. Asphalt consists of compounds of hydrogen and carbon with minor proportions of nitrogen, sulfur, and oxygen. Natural asphalt (also called brea), which is believed to be formed during an early stage in the breakdown of organic marine deposits into petroleum, characteristically contains minerals, while residual petroleum asphalt does not.

The use of asphalt is very old, dating back to its use as a water stop between brick walls of a reservoir at Mohenjo-Daro (about the 3rd millennium BC) in Pakistan. In the Middle East it was extensively used for paving roads and sealing waterworks, important applications even today. The Pitch Lake on the island of Trinidad was the first large commercial source, but natural sources have since declined in importance as petroleum became the major source. Gilsonite, wurzilite, and similar vein asphalts have special uses in heat-resistant enamels; they are hard and are mined like coal. Petroleum asphalt is produced in all consistencies from light road oils to heavy, high-viscosity industrial types.

Why Are Roads Made of Asphalt?

Asphalt softens when heated and is elastic under certain conditions. The mechanical properties of asphalt are of little significance except when it is used as a binder or adhesive. The principal application of asphalt is in road surfacing, which may be done in a variety of ways. Light oil “dust layer” treatments may be built up by repetition to form a hard surface, or a granular aggregate may be added to an asphalt coat, or earth materials from the road surface itself may be mixed with the asphalt.

Other important applications include canal and reservoir linings, dam facings, and other harbour and sea works; asphalt so used may be a thin, sprayed membrane, covered with earth for protection against weathering and mechanical damage, or thicker surfaces, often including riprap (crushed rock). Asphalt is also used for roofs, coatings, floor tilings, soundproofing, waterproofing, and other building-construction elements and in a number of industrial products, such as batteries. For certain applications an asphaltic emulsion is prepared, in which fine globules of asphalt are suspended in water. See also bitumen.

Repair or Replace? What To Do About Your Aging Asphalt Parking Lot

Nothing lasts forever, and asphalt is no exception. There comes a time with every parking lot where you need to ask whether it’s time to repair it, or replace it altogether.

A properly paved asphalt lot can last 20 – 30 years, but the lifespan and condition of any lot depend on many factors. Let’s take a look at the various kinds of damage and repairs, and when you should replace a lot entirely.

The Types of Asphalt Damage

Cracking
Cracking can take many forms, including shrinkage, widening, edge cracks, slippage, alligator cracks, and reflection. Cracks are caused by many different factors, such as water penetration, oxidation from the sun, freezing, and thawing, and poor initial construction. Even the most minor cracks should be sealed as soon as possible, as small cracks can grow into bigger problems. Water or other debris can settle inside, causing the crack to grow, softening the base, and further threatening the integrity of the pavement. Larger cracks may be a warning sign of deeper issues.

Rutting
Rutting is when the pavement shows depressions, or grooves, from wear and tear caused by wheel loads. Ruts can be dangerous, leading to vehicles hydroplaning (from ponded water) that can result in loss of driver control. They can also be a result of deeper sub-soil or design problems, and lead to further deterioration. Ruts less than ⅓ inch deep can generally be left as is, but deeper ruts should be leveled and resurfaced.

When It’s Time To Repair

Crack Sealing
Crack sealing is exactly what it sounds like – filling small cracks to prevent further damage. Cracks that are straight or less than a quarter-inch wide can easily be repaired with a liquid filler. Before sealcoating or resurfacing, all cracks and existing damage must be repaired, so crack sealing is the first step towards further repair and necessary ongoing maintenance responsibility. A yearly schedule of crack sealing is best to prolong the life of your lot.

3 Types of Damage Asphalt Sealing Prevents

Asphalt sealing is an important part of maintaining a driveway or parking lot made of this material. It should be performed every two to three years to protect the pavement from developing damage that could shorten its life span. If you miss this maintenance, you could develop one or more of the issues below.

What Can Happen When You Skip Asphalt Sealing

1. Freeze-Thaw Expansion & Fracturing
The winter can be absolutely brutal on asphalt, particularly due to the freeze-thaw cycle. This occurs when water seeps down into the pavement, freezes, and expands — resulting in cracks. As the water thaws, it will then creep even deeper into the material, repeating this process and leading to numerous fractures. Asphalt sealing prevents this by covering any small cracks in the material and keeping water out year-round.

2. Sun Drying

The chemical bonds in the pavement begin to deteriorate, leading to cracks and other damage on the surface. Asphalt sealing prevents this by covering the blacktop in anti-oxidation additives and other aggregates that act as a barrier.

3. Surface Softening
Since asphalt pavement is predominantly used by vehicles, it will most likely experience some auto fluid spills. When oil, gas, and similar liquids fall onto the surface, they will be absorbed by the asphalt and cause it to soften. While these spills can be easily cleaned up in most cases, overtime they can result in cracks or a deterioration of the aggregates comprising the blacktop.
