3.1 Introduction. The unit cost of logging or road construction is essentially derived by dividing cost by production. In its simplest case, if you rented a tractor with operator for $60 per hour - including all fuel and other costs - and you excavated 100 cubic meters per hour, your unit cost for excavation would be $0.60 per cubic meter.

Longitudinal Joint in Asphalt Pavement A longitudinal joint occurs in an asphalt pavement when a fresh batch of hot-mix asphalt (HMA) is laid adjacent to an existing lane. It is required to pave the width of a road in multiple lanes because paving the full width of the pavement in a single pass is usually impossible.

However, if the thickness in this scenario was changed to 1 inch, the speed could increase to 52 feet per minute and 64 feet per minute, respectively, to maintain the 200-TPH production rate. "Obviously, higher production rates will drive even higher paving speeds," Humphrey said.
