Concrete pavement is preferred over asphalt for roadway or trail surfaces in several regions of the country. The cost model assumes a 3-inch pavement depth.
How the Default Unit Cost was Determined
Ten surveyed projects specified concrete paths and the median unit cost is employed in the model. The selected median value of $142/cubic yard is the mid point between the cost of $84/cubic yard for an Iowa DOT project and $189/cubic yard for widening a bike lane by 1 foot in Wisconsin.
