Asphalt may seem like an indestructible material, but over time, it can begin to show wear and tear through cracking, raveling, potholes, etc. Our Kansas City asphalt repair experts are adept at fixing problems before they become costly.
There are two types of patching asphalt repairs in pavement maintenance: Remove and Replace (R&R) and Skin or Surface Patching.
REMOVE & REPLACE
When cracks are visible in alligator cracking, potholes, sags, ruts, depressions, and lateral displacement, the best option is to remove and replace patch the failed area. This process consists of saw cutting the area where structural damage has occurred, removing the area, and patching it back with hot mixed asphalt.
Another option we use in our Kansas City asphalt repairs is a 2” mill patch of asphalt's surface layer where only the surface portion of the asphaltic surface has been damaged. You can remove that surface layer before it starts to damage the base layer of asphalt.
Paving and Overlays
PAVING ON GRADE
When paving on grade, new asphalt is placed on finished subgrade or aggregate base material. The new asphalt is laid down using the same process as the overlay below.
An asphalt overlay is simply the process of installing a new surface layer of hot mix asphalt directly over existing asphalt on either parking lots or roads. To be a candidate for an overlay, pavement should be relatively sound without large areas of base failure. Before resurfacing, pavement repairs and transitions must be made. Cracks can be filled with a rubberized crack sealer and a tack coat applied over the entire surface. A new layer of asphalt is then placed.
Fabric overlay is a way to delay reflective cracking, although it will not prevent such cracking. Before placing a new layer of hot mix asphalt, a geotextile fabric is embedded in a liquid asphalt binder over the entire surface. The fabric/binder combination forms a membrane that helps keep water out of the base. The cost is approximately one-third greater than a basic overlay.
Sealcoating provides a layer of protection from the elements, water, oils, and U.V. damage. Sealcoating extends asphalt pavement life and can help reduce the friction commonly associated with asphalt pavement. We recommend sealing every 3 to 5 years, depending on wear.
We provide Kansas City seal coating services on parking lots, roads, and driveways while offering crack filling and parking lot striping. The sealer can be applied to an asphalt surface by hand squeegee, machine squeegee, or sprayer. Typically, driveways are squeegeed while parking lots and roads are sprayed after being trimmed by a squeegee.
Over time asphalt binder is exhausted, and the aggregates begin to unravel due to the absence of the binding cement. Sealcoating helps to delay this process when applied properly. The rate of pavement deterioration depends upon the traffic volume as well as climatic conditions. The next step is the development of minor cracks, which widen and deepen with time. If the cracks are not repaired at this stage, water seeps into the base courses and damages the pavement’s load-bearing capacity. It is evidenced by rutting, shifting, and serious alligatoring. The pavement then must be either overlaid or completely removed and reinstalled, depending on the condition.
Asphalt pavement is a large investment and can last for decades if it’s well maintained. Asphalt crack sealing is an extremely economical and effective way to protect your original investment. The formation of cracks is due to many factors such as thermal stress, fatigue, and reflective cracking from the underlying pavement. When cracks appear, water and moisture enter the asphalt and penetrate the subgrade. Over time, more cracks will form, and potholes will begin to appear. If left untreated, these issues will eventually create a large enough problem that your asphalt will need to be removed and replaced.
Crack sealing is the sealing cracks that are larger than one-quarter of an inch utilizing hot rubberized asphalt sealant. We only use quality crack sealants that are engineered to withstand the extreme temperatures of our climate during all of our Kansas City crack sealing jobs. It is vital to begin a crack sealing program at the first sign of cracks developing in your pavement, anywhere from 2 – 5 years after initial asphalt installation.
Striping and Signage
The safety of the patrons and customers visiting your property should be priority number one. Faded lines and markings can confuse drivers and can even lead to accidents. A fresh coat of paint will ensure cars can navigate your parking lot safely.
New lines and markings will make for great curb appeal.
Indicating clear and proper access for the disabled is a very important aspect of line striping. Also, ADA compliance thru pavement markings and signage ensures your business will not face fines and penalties.
