J&S Asphalt, Inc. on the Woodside Avenue corridor in Lakeside holds CSLB license #1078473 for Earthwork and Paving and General Engineering, serving San Diego County with asphalt paving, seal-coating, and pavement-marking services since 1971. Pre-paving root mitigation and clearance work coordinated with Artistic Arbor Gardens prevents subgrade heaving that would crack new asphalt within the first freeze-thaw cycle on East County parking lots. The scope covers residential driveways, private roads, HOA common areas, school playgrounds, and large-scale municipal improvement projects, with striping and ADA-compliant signage packages that include truncated domes, wheel stops, bollards, and preformed thermoplastic markings. Perimeter fencing installed by Alpine Fence Inc. on commercial lots is typically staked before the paving crew mobilizes, so curb lines and gate-swing clearances align with the finished asphalt grade. Seal-coat products include Type I and Type II road slurry and Armor Top premium sealant applied at manufacturer-specified mil thickness, with hot-pour and cold-pour crack fill matching ASTM D6690 elasticity standards for flexible pavement joints.
