Four Areas of Asphalt Maintenance

When looking at asphalt maintenance it can be divided into four areas. The primary cause of asphalt failing is the penetration of water into the asphalt base. Over time, it will become brittle and dry with the aggregate beginning to wear away and cause cracks that will let water penetrate into the base of the pavement. When the water seeps into the crack it causes the base material to move and settle. This leads to the surface cracking in a pattern that is grid-like When the payment has reached this stage there are only two options, which replace the old asphalt or patch repair it.

Patch repair

It deals with areas that are isolated. Using a backhoe and saw-cutting the pavement is removed. They can also use a grinding machine. Once the old asphalt is removed, it is replaced with new asphalt. The removal method determines the amount that is removed. The removal depth should be equal to one point five times the original thickness of the asphalt. You may also have to replace the base-rock to match the adjacent areas to allow for base support that is uniform. The amount of removal should be extended twelve inches past the area that failed.

Asphalt overlay

This asphalt maintenance is affordable and provides a new wearing surface. When dealing with asphalt overlay there is a certain factor you need to be aware of, which include:

• Overlay thickness-it should be a maximum of two point five inches with a minimum of one point five inches
• Smooth transitions-when you are considering where to grind the existing pavement down remember not to grind down the overlay section to match the existing structure. If you do this could weaken the strength of the overlay. They will grind the existing payment down to where they meet flush together to prevent this.

Inlay and pulverize in place

Both of these areas of asphalt maintenance are accomplished using a milling machine. During the process of inlay, it removes a depth of the existing asphalt, which is many times a previous overlay. This will let the contractors put the asphalt back to the pre-inlay elevation. The method of pulverize-in-place will reduce all of the asphalt to particles that are base-rock size.

Seal coating

This is an important part of extending the life of the asphalt and it should not be overlooked. Seal coating is a mixture of mineral fibers, emulsified asphalt, and water along with other admixtures. This will seal the top layer of asphalt to prevent water from penetrating the pavement surface and protecting the top layer from wear from sun exposure and oxidation. It is what gives the asphalt its even black surface.

The Importance of Parking Lot Line Painting and Pavement Marking

In business today it's important to be professional. This includes the upkeep of property maintenance inside and outside of the business. Parking lot line painting is one of the most important aspects of external property maintenance and this article explains three excellent reasons why.

1) Appearance

The parking lot of a business acts as a welcome mat for customers and can often act as a first impression to new clients. If the parking lot pavement markings are worn and barely visible it may give the impression to some clients that the owners are irresponsible or that they don't care about the way their property looks. Parking lots simply look better with a fresh coat of high grade traffic paint on the stall lines, handicap symbols, arrows, speed bumps and any other pavement markings the lot might have. When line painting is done it allows that mat to say "welcome" again.

2) Parking Organization

If there is no visible lines to indicate parking spaces in a parking lot, people will park anywhere and everywhere they can fit their vehicle. This is not good since it increases the chance of people getting boxed in and unable to get out of the lot. When parked vehicles are in disarray it can also increase the chance of dings and scratches to vehicles if navigation around the lot is tight and difficult. Parking stalls and drive lanes have regulated sizes for these reasons and a nicely painted lot keeps the parked traffic organized and moving vehicles can be driven through the area safely and easily.

3) Space Maximization

I can't count the number of times I've seen 20 vehicles in a "full" parking lot that could easily fit 24 or 25 automobiles if it had been given the correct line painting job done. It doesn't seem like much but let's say it's a restaurant that averages $50.00 per bill. That adds up to about $200.00 - $250.00 in revenue. This to me would be the most frustrating parking problem for the business owner since most of the time if people can't park at the establishment, they don't shop there either. Painting proper stall lines allows optimal space maximization that fits as many vehicles as the parking lot can safely manage.

These are three basic problems that can be easily avoided if the correct pavement markings are applied to the lot. As long as parking lot line painting is done by professionals it can be one of the quickest and effective aspects of external property maintenance.

What does this symbol actually mean? - Adrian Treharne

Some of the world’s most recognizable symbols exist to sell products. Others, to steer traffic or advance political causes. But there’s one whose main purpose is to help people. You may know it as the wheelchair symbol, but its formal title is the International Symbol of Access. But what does the symbol actually mean? And what is its purpose? Adrian Treharne explains.

Creating a Handicap Accessible and ADA Compliant Parking Spot

When business owners are designing their location's parking lot, they should be sure to keep in mind their handicapped customers. The Americans with Disabilities Acts establishes a strict set of guidelines that must be followed by every business with a parking lot. Failure to comply with ADA regulations can result in fines. Luckily for business owners, the ADA specifications are rather straightforward.

ADA regulations require that a business owner have a certain number of handicapped parking spots. According to Adaptive Access, this number depends on how many parking spots a location offers. For small businesses with only 25 parking stalls, only one accessible parking space is necessary. As the number of parking stalls increases, though, so does the number of required accessible parking spots. At the maximum, for locations with more than 1,000 regular parking spaces, handicapped parking spaces must account for 20 spots, plus one for every extra hundred spots.

When deciding on the location of a handicap-accessible parking spot, there are a few rules that a business owner needs to observe. The accessible parking spots must be the closest parking spot to the store. At some businesses, the closest parking spot may not be suitable for an accessible parking spot. For example, the closest spot may be located on an extreme slope, or the ground may have large cracks in it. If this is the case, than the accessible spot needs to be as close as safely possible to the business' entrance.

The pathway from the handicapped parking space to the store must also be accessible to customers with disabilities. A handicap-accessible parking spot cannot be located on the top floor of a garage unless there is a ramp or elevator that leads to the store entrance. An accessible spot may also not be positioned in a spot where there is an extreme slope. If the path to the store crosses in front of any vehicular traffic, than the area must feature a clearly marked pedestrian-crossing zone.

Each handicap-accessible parking spot must be at least eight feet wide. Handicap-accessible parking spots must have two five-foot wide pedestrian loading zones, into which a wheel chair or electric scooter can easily fit. Two adjacent handicapped parking spaces can share one loading zone. According to the Florida Section of the Institute of Transportation Engineers, the parking spot must be outlined in blue, and needs to be repainted as necessary so that it is always clearly defined. Loading zones must be painted with diagonal stripes to denote that they are not parking spots.

The international handicap symbol should be painted on the pavement furthest from the curb so it is easily visible as a car approaches the stall. You can use the 39 inch (1 meter) international handicap parking stencil which is made to Federal ADA specifications. However, you should verify size requirements with your local zoning office as state specifications can vary and change without notification. For example, California requires the 36 inch handicap parking stencil and Florida requires the 60 inch handicap pavement stencil.

Handicap parking stencils are available in a range of sizes. A 21 inch is typically used in stadium row seating and the 72 inch is typically used at airports and large facilities.

ADA regulations say a handicapped parking spot must always have a handicapped parking sign placed in the front of the spot as well. A handicapped parking sign needs to be posted at a height so that it will always be viewable and mounted high enough for other cars to see - generally speaking, the parking sign needs to be posted five feet off the ground. The parking sign must also show the international symbol of accessibility. Once inside, you should include handicap bathroom signs.

For every eight handicapped parking spots, at least one spot needs to be accessible to vans. The van-accessible handicapped spot must still be eight feet wide, but the loading zones must be eight feet wide instead of five feet. The parking sign also needs to clearly designate that the spot is for vans, though regular vehicles with a permit may park there.

Designing a parking lot with handicapped accessibility in mind is key. Not only will it prevent a business owner from being fined, but it will also go a long way to pleasing any handicapped customers a business may have.

Asphalt Pavement Principles: Density and Durability

More than 18 billion tons of asphalt pavement are in place on U.S. roads. Long-lasting asphalt pavements are the result of collaborative partnerships between researchers, manufacturers, paving contractors, and agencies. When striving to make asphalt pavements more durable, research and lessons learned show that density is an important factor. This video talks about several keys to achieving proper asphalt pavement density, as well as new technologies that are moving the asphalt industry forward.

Your Driveway - The Stages and Solutions

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.
