RDI 14-04 Design Values Estimating Guidelines For Hot

2014-5-22  Designers when estimating hot-mix asphalt (HMA) quantities for US Customary projects, including appropriate unit weight values to be used in the required calculations. Guidelines for estimating and utilizing Quality Units (QU’s) for HMA items are also included. Background HMA quantities are calculated by first determining the volume of each HMA item in units of cubic feet (ft3). The resulting volume is then multiplied by the appropriate value of HMA
