Commercial and Residential New Asphalt Paving
As a Central and Southern Indiana asphalt contractor, C.A.S.E. has over 30 years of experience in placing new asphalt paving, asphalt parking lots, streets, roads, and driveways.
Asphalt pavement is utilized in a variety of different applications because of its durability, cost-effectiveness, simplicity of construction, and strength. It is the material of choice for parking lots, roadways, and driveways across the nation because asphalt withstands heavier loads and, when combined with proper asphalt maintenance, lasts for many years.
In order to maximize the life of your asphalt parking lot, it is important to develop a pavement management plan involving routine inspections and ongoing preventative maintenance. The following are common asphalt maintenance procedures for parking lots:
Asphalt Repair & Patching
Patching is a common asphalt repair on areas of pavement with potholes. Potholes occur when water seeps into pavement through unsealed or improperly sealed cracks. When the water freezes, it expands and enlarges the crack. When the ice under the pavement melts, a void is left. Surrounding pavement falls into the void and forms a pothole.
Asphalt Repair Procedure
This process consists of filling the affected areas with hot or cold asphalt mix, depending on the season and/or site location. Potholes will be cleared of all debris and filled with hot or cold asphalt and compacted with a vibratory roller or plate compactor.
Asphalt Removal & Replacement
As asphalt pavement progresses through its performance lifecycle, its appearance diminishes over time. Fine hairline cracks spread and deepen within the asphalt. Without ongoing maintenance, water may enter through cracks and holes may form, undermining the substrate. In this case, the most effective form of repair is to remove and replace the deteriorated area.
This process consists of several important steps to ensure that the repair is performed properly. The area(s) will be saw cut or milled and the existing deteriorated asphalt will be removed to the approximate specified depth. The existing stone base will be compacted and a tack coat will be applied to the remaining asphalt edges to guarantee proper bonding. Hot asphalt will be installed and compacted with a vibratory roller.
The cost for asphalt removal & replacement depends upon the geographic location, the amount of grading and substrate work required, and other site-specific factors.
Covering larger areas of asphalt failure, a more cost-effective solution is to resurface the asphalt pavement (also referred to as overlay). If you notice grade depressions (standing water on the pavement) and/or large sections of alligatored areas (interconnecting cracks forming a series of blocks resembling an alligator’s skin), it is a good idea to have your pavement resurfaced. In most instances this is a maintenance item only. Existing cracks will reflect through your new pavement over time.
Asphalt Resurfacing Procedure
This process consists of several steps including preparing and cleaning the area prior to performing work, leveling asphalt of low areas, grinding of all transitions, adjusting of all drainage structures, and many other steps unique to each site.
An option that may be included with asphalt resurfacing is Petromat. Petromat is a non-woven, petroleum-based geotextile fabric used to retard reflective cracking between
the existing pavement and the newly installed asphalt surface. This fabric acts as a water- proofing membrane, while
also adding structural support and strength.
In low areas, hot asphalt is installed at various depths to adjust pitch to proper grades while increasing parking lot strength.
In areas requiring the resurface to tie into other existing surfaces (i.e., concrete, etc.) asphalt is removed along the perimeter to allow the proper depth of asphalt on the edge.
In areas requiring the resurface to tie into other existing surfaces (i.e., concrete, etc.), asphalt will be milled and replaced to allow proper depth and transitions. An asphalt milling machine is used to remove an appropriate depth of pavement in a grinding process. The spoils can then be hauled off and recycled.
Asphalt Maintenance Facts
As soon as freshly laid hot asphalt pavement mix begins to cool, the aging process begins.
When oxygen in the air and water combine with an asphaltic binder of the pavement, a chemical change takes place. At first, this process is necessary for the pavement to become hard and firm. Later, if this process is not arrested, a complete deterioration of the asphaltic binder will take place and reduce the pavement to a layer of loose stone.
Enemies of a parking lot include gas, oil, sun oxidation, salt, water penetration, and hot or cold weather.
Protect Your Investment
In addition to routine inspections and ongoing maintenance, sealcoating asphalt pavement with a coal tar or asphalt-based emulsion slows pavement deterioration by protecting against the enemies of a parking lot. However, for maximum benefit, sealcoat needs to be applied approximately 12 months after the initial application and then on a regular basis, about every 24 to 48 months, thereafter.
Asphalt Contractor Services
C.A.S.E. Construction, Inc. approaches each project the same way and always with the same goal in mind–to save customers time and money like every good asphalt contractor should. First, our professional estimators, with cameras and measuring tools in hand, conduct a physical inventory of the parking lot to develop an accurate plan of repairs and maintenance. Never taking short cuts, our methods are thorough, including checking catch basins and parking bumpers.
During the evaluation process, our estimators are always prepared and willing to discuss any concerns, offer suggestions, and answer any questions you may have. At the end of the evaluation, we present you with a proposal including, as necessary, photos and a site map (photos and site map are included based on the scope of the job). Depending on your needs and budget, we can also offer options, alternatives, and different price ranges. All of our basic site evaluations and consulting sessions are complimentary.
