What is asphalt paving in construction?

Asphalt paving is the wearing surface of the paving assembly and the last major sitework scope before striping. It lives on the civil paving plan, which hatches each pavement type, and the pavement section details, which give lift thicknesses for standard duty stalls and heavy duty drive aisles, with the geotech report behind the section design. A paving subcontractor owns the scope, often under the sitework contractor on commercial work. The section goes down in lifts: a base course (binder) with larger aggregate provides structure, and a surface course (wearing lift) with finer aggregate provides smoothness and density, with a tack coat between lifts. New estimators get burned in predictable ways: they price one blended thickness across the whole lot when the heavy duty aisles and dumpster approach carry a thicker section, they quote per sf when the paver bids per ton, and they miss that liquid asphalt pricing moves with the oil market, which is why many paving bids carry an asphalt cement price adjustment clause.

Asphalt is measured by converting area to weight. Take off the sy of each pavement section separately (sf divided by 9), read each lift thickness from the section detail, and convert using the rule of thumb of about 110 lbs per sy per inch: tons = sy x inches x 110 / 2,000. Cost drivers are total tonnage, the number of lifts and mobilizations, the mix designs (surface mix typically costs more per ton than base mix), haul distance from the plant, and night or phased work. Small placements carry a much higher per-ton price because plant minimums and mobilization spread over little tonnage.
