4. ESTIMATING ROAD CONSTRUCTION UNIT COSTS

Road construction superintendents can often estimate the number of meters per hour that their equipment can build road based upon local experience after looking at the topography. The engineer's method is to calculate the number of cubic meters to be excavated using formulas or tables for calculating earthwork quantities as a function of sideslope, road width, cut and fill slope ratios.

Pavement Terminology — Pavement Engineering Inc.

Subbase – a layer of aggregate designed in thickness and quality placed on top of the native soil or subgrade that serves as a foundation for the base layer. Subgrade – the native soil or portion of the roadbed on which a pavement surface, subbase, base or layer of other material is placed. Get price
