This service includes excavation of existing material, establishment of a stable subgrade, installation of a compacted aggregate base, and the precise placement of hot mix asphalt (HMA) binder and surface courses. Our goal is to create a structurally sound and visually appealing pavement that withstands traffic and environmental stressors.
Our process begins with a thorough site analysis, assessing soil conditions, drainage requirements, and anticipated traffic loads. We then develop a detailed plan, specifying aggregate base thickness, asphalt mix designs (e.g., dense-graded Superpave mixes for heavy traffic or open-graded friction courses for improved drainage), and compaction targets. This upfront engineering ensures the pavement's structural integrity and longevity, preventing premature failure due to inadequate foundational support.
For properties in Pomona, this detailed approach is critical because the local climate, with its hot summers and occasional heavy rains, demands specific material considerations. We select asphalt mixes formulated to resist rutting under high temperatures and to maintain flexibility during cooler periods, which helps prevent thermal cracking. Proper drainage planning is also paramount to mitigate water infiltration into the subgrade, a common cause of pavement deterioration.
Homeowners often ask about the lifespan and maintenance of new asphalt. A properly installed asphalt pavement in Pomona can last 20-30 years with regular maintenance like sealcoating every 2-5 years and prompt patching of minor damage. We also advise on initial curing times, typically recommending light traffic after 24-48 hours and full traffic after several days, depending on ambient temperatures and asphalt mix specifics.
The structural integrity of asphalt pavement in Pomona depends heavily on the aggregate base and the asphalt mix design because these elements directly influence its ability to support loads and resist environmental stress. A well-compacted, properly graded aggregate base provides uniform support, distributing vehicle weight evenly and preventing localized settlement or cracking in the asphalt layers above. Without this solid foundation, even the best asphalt will fail prematurely.
In Pomona's climate, selecting the correct asphalt mix is crucial. We often use mixes designed with specific binder grades (e.g., PG 64-10 or PG 70-10) that offer enhanced resistance to rutting during hot summer months and better flexibility in cooler temperatures. This prevents common issues like alligator cracking and deformation under heavy traffic, which are exacerbated by temperature fluctuations.
Achieving optimal compaction during installation is equally vital because it dictates the density and strength of the finished pavement. We target specific density percentages, typically 92-97% of theoretical maximum density, using vibratory rollers. This reduces air voids, making the pavement less permeable to water and more resistant to oxidation and wear, which extends its service life significantly.
We begin by excavating existing material to the required depth, establishing proper drainage slopes, and compacting the subgrade to at least 95% of its maximum dry density. This creates a stable, uniform foundation for the new pavement.
A layer of crushed aggregate base material, typically 4-8 inches thick depending on traffic load, is spread and compacted in lifts to achieve specified density. This provides critical structural support and further improves drainage.
A tack coat is applied to bond the aggregate base to the first layer of hot mix asphalt (HMA), the binder course. This layer, usually 2-3 inches thick, provides the bulk of the pavement's structural strength and is compacted immediately after placement.
The final surface course, a finer HMA mix, is then applied, typically 1.5-2 inches thick, and meticulously compacted using breakdown, intermediate, and finish rollers. This creates a smooth, dense, and durable wearing surface with precise grade and slope.
