This service includes initial site assessment, grading for proper drainage, compaction of subgrade and aggregate base, and the final paving with precisely heated asphalt material, followed by compaction to achieve the specified density and smoothness. We focus on creating a structurally sound pavement that performs reliably under daily use.
Our approach begins with a thorough evaluation of the existing site conditions, including soil type and drainage requirements. We then excavate to the necessary depth, establish proper slopes for water runoff, and install a compacted aggregate base. This base layer is critical; it distributes the load from traffic evenly and prevents premature cracking or rutting in the asphalt above. We use specific aggregate blends, typically crushed rock, that compact effectively to form a stable foundation.
For Los Angeles properties, selecting the right asphalt mix design is crucial because of the region's warm climate and occasional heavy rains. We specify asphalt concrete mixes with appropriate binder grades (like PG 64-10 or PG 70-10, depending on expected traffic and temperatures) that resist softening in heat and cracking from thermal cycling. This attention to material science ensures the pavement maintains its integrity and appearance over time, even with intense sun exposure and urban heat island effects.
Homeowners often ask about the lifespan and maintenance of new asphalt. A properly installed asphalt pavement can last 15-20 years before requiring significant rehabilitation, provided it receives routine maintenance like sealcoating and crack filling. We advise on a maintenance schedule that extends the life of your investment, protecting it from UV damage and water infiltration, which are primary causes of deterioration.
After the hot mix asphalt is laid and compacted, it requires a curing period. While light traffic can often resume within 24-48 hours, the asphalt continues to harden and gain strength for several weeks. We provide clear instructions on post-paving care, including avoiding heavy vehicle loads and sharp turns during the initial curing phase, which helps prevent surface distortions and ensures the pavement reaches its full design strength.
Proper asphalt paving is essential in Los Angeles because the region's unique climate and soil conditions directly impact pavement longevity and performance. The intense Southern California sun and high ambient temperatures can accelerate oxidation and binder aging in asphalt if the correct mix design and application techniques are not used, leading to premature cracking and raveling. We select asphalt grades specifically formulated to resist these thermal stresses.
Furthermore, Los Angeles experiences a range of soil types, from expansive clays in some valleys to sandy loams near the coast. An improperly prepared subgrade or inadequate aggregate base will lead to pavement failure, such as settlement, alligator cracking, or potholes, regardless of the asphalt quality. Our detailed site assessment and base preparation address these specific geological challenges, ensuring a stable foundation for the pavement.
Effective drainage is also critical in Los Angeles, especially given the infrequent but often heavy rain events. Poorly designed slopes or inadequate drainage systems can lead to standing water, which infiltrates the pavement structure, weakens the base, and causes accelerated deterioration. We meticulously grade and establish positive drainage away from structures and traffic areas, protecting your investment from water damage.
We begin by clearing the site, removing existing pavement or vegetation, and then precisely grading the subgrade. This step establishes the correct slopes for positive drainage, which is crucial for preventing water accumulation and ensuring the pavement's long-term stability.
A robust aggregate base layer, typically 6-12 inches of compacted crushed rock, is installed and compacted to 95% Modified Proctor density. This base distributes traffic loads evenly, preventing stress concentrations that could lead to cracking in the asphalt surface.
We apply the hot mix asphalt in one or more lifts, typically at temperatures between 280-325°F, using a paver to achieve uniform thickness and smoothness. The specific asphalt mix design (e.g., Type A or Type B with appropriate PG binder) is chosen based on expected traffic and environmental conditions.
Immediately after paving, the asphalt is compacted using multiple passes with vibratory and static rollers to achieve the specified density, typically 92-97% of theoretical maximum density. This critical step locks the aggregate particles together, preventing rutting and ensuring a durable, smooth surface.
