Western Asphalt Company in Chula Vista provides asphalt paving, patching, sealcoating, and striping services for residential driveways, commercial parking lots, and HOA common areas from its Zenith Street base in the 91911 corridor. Parking-lot projects often begin with grading and drainage assessment, and the site-preparation earthwork on larger commercial pours coordinates with landscape contractors such as SouthWest Environments Landscape Services for perimeter planting and irrigation tie-ins. ADA-compliant accessibility upgrades — including truncated-dome detectable warning surfaces, van-accessible stall dimensions, and compliant signage — are part of the company's commercial repaving scope along Chula Vista's Broadway corridor. Full-depth asphalt removal and replacement on failed subgrades is managed in coordination with general contractors such as Fausto Construction Inc. when the paving falls within a larger site-development or tenant-improvement project. Heavy-duty commercial specifications call for a minimum four-inch compacted Class II aggregate base topped with three inches of Type B PG 64-10 hot-mix asphalt, machine-laid and steel-wheel rolled to 95-percent compaction per Caltrans Section 39 standards.
