UNCONVENTIONAL MIX YIELDS INCREASED STRENGTHS WITH LOWER ASPHALT CONTENT

The benefits are described of the Stone Filled Mix which allows lower asphalt content because of adjustments to the gradations. The increased amounts of stone in the mix, improves 3 items of condition and performance: lowers the asphalt content demand; decreases lateral displacement under the roller; and remarkable improvement in support strength for batch truck traffic during construction. The Mix has been used as a base and levelling course with a chat aggregate asphaltic surface course used to reduce skid resistance and prolong wear. In a project in which Stone Filled Mix was used as a base mix, it contained 87 percent limestone and 13 percent sand. Production and laydown of the mix was no different than conventional mix.
