GRADING AND NEW PAVING
New Paving is the application of new hot asphalt applied to either native soil or rock base material. Thickness of the asphalt section or the size of the rock used will change depending on how much weight and traffic the surface will be subject to. The asphalt may be paved in multiple lifts as well to be sure the proper compaction is reached.
It is very common to place a section of base material under new asphalt; base material, or more accurately, rock base, is a very frequently used mixture of rock and sand, which is able to attain a high rate of compaction. The utilization of base material provides a strong underpinning to the new asphalt being placed. Heavy traffic areas will destroy new asphalt if it is not on strong base material at the time of the installation.
Finally, grading of the base material is required. Grading is the movement of dirt or base material to achieve the proper elevations prior to paving. Grading is necessary to smooth and compact the finish surface in order to be ready to receive asphalt which will mirror the grade as it has been left.
ASPHALT REPAIR AND RESURFACING
Asphalt repairs can be completed in a few different manners. One option is to remove and replace only those areas that are particularly damaged or deteriorated.
Another option is to resurface or patch only the affected areas. Resurfacing includes the use of fine asphalt mixtures to patch areas where only a thin layer of asphalt is necessary or desired. The fine mix asphalt is usually used to fill low areas where water pools and doesn’t drain or worn areas that need to be patched. This application is typically bid as part of a larger project for those small areas that need to be brought up to grade or patched.
ASPHALT REMOVAL AND REPLACEMENT
Asphalt removal and replacement consists of removing and disposing of the existing damaged asphalt and repaving the area with new hot asphalt. When an asphalt surface has failed beyond the point it can be salvaged asphalt removal and replacement is necessary.
OVERLAYS AND FABRIC OVERLAYS
Overlaying includes the use of fine asphalt mixtures to patch areas where only a thin layer of asphalt is necessary or desired. The fine mix asphalt is usually used to fill low areas where water pools and doesn’t drain or worn areas need to be patched. This application is typically bid as part of a larger project for those small areas that need to be brought up to grade or patched.
Petromat is a pavement reinforcing fabric specifically designed for the paving industry. Its primary function is to strengthen and reinforce the base course of asphalt upon which the new asphalt will be placed. An additional benefit is that it helps to mitigate mirror or reflective cracking (cracks in the existing asphalt) from coming up through to the new asphalt. The process involves laying a binder coat of hot oil which enables layers of asphalt to stick to one another, then laying the Petromat Fabric, and finally, overlaying these with a layer of asphalt, typically between 1-1/4″ and 2″ thick.
GRINDING
Grinding asphalt has a number of different applications depending on the particular result desired. Grinding is typically done on a linear foot basis to enable a smooth transition from an existing asphalt surface to one that will be newly paved. Usually a small grinder is used to grind away 1″ to 2″ of existing asphalt, so that as the new asphalt that is laid adjacent to the old asphalt has a smooth transition from one to the other.
CRACKFILLING
Asphalt crackfilling places materials into non-working or low movement cracks to reduce the infiltration of materials and water into the cracks. Crackfilling can extend the life of your pavement if done properly. By sealing cracks in your pavement your preventing sand and rocks from making their way to the surface by avoiding water based erosion. Asphalt crackfilling will keep new cracks from forming and minimize crack growth. It is important to treat the problem areas in your asphalt while they are small.
SEAL COAT AND STRIPING
Asphalt Seal Coat is the most important maintenance element of your driveway or parking lot. Seal Coat is applied over the asphalt and is designed to protect asphalt pavements from the damaging effects of the environment, including moisture, pollutants, and oxidation. Aside from the beautiful black finish is adds to your asphalt, sealcoating also minimizes raveling (the loss of aggregate) and fills minor voids in the surface. Seal Coats make a smooth and attractive surface that resists aging and protects the valuable pavement. Seal makes a smooth and attractive surface that resists aging and protects the valuable pavement. A newly sealcoated and striped parking lot creates an attractive and welcoming feeling to a visitor.
Once the seal coat has dried, new traffic paint (striping) is then applied to define traffic patterns, designated parking areas, etc. We can also provide all of your signage needs as well including ADA signage.

CONCRETE REMOVAL, REPLACEMENT and NEW INSTALLATIONS
Because the density of concrete holds up against water erosion better than asphalt, it is primarily used to form curbs and gutters but can also be used as a traffic surface. The scope of work for concrete installation will change depending on how much weight and traffic the surface will be subject to.
ProWest Engineering, Inc. specializes in new concrete and concrete maintenance including but not limited to sidewalk, flowlines, curbs, gutters, driveway aprons and handicap ramps.
ADA COMPLIANCE
The “ADA” (Americans with Disabilities Act) has set forth design standards for paving and striping that must be followed to be in compliance with the law. ProWest Engineering, Inc. can provide you with the expertise to remove your existing non compliant features and install new ADA compliant ramps and handicap access. This includes handrails, signage, path of travel striping and detectable warning tiles.
