Experimental Study on Performance of Large Stone Permeable Asphalt Mixtures

Abstract:

This study focused on the performance of the Large Stone Permeable Asphalt Mixture (LSPM) with neat asphalt and its feasibility to use as asphalt pavement flexible base. For comparision, LSPM mixtures were designed respectively with neat 60/70-grade asphalt and modified asphalt and the performance of LSPM was studied and compared by volume index test, draindown test, Hamburg Wheel-tracking Test and dynamic modulus test. The results showed that the performance of LSPM with modified asphalt was superior to LSPM with neat asphalt and cellulose fiber, but draindown and rutting performance of LSPM with neat asphalt met requirements of corresponding specification and dynamic modulus of LSPM with neat asphalt had the same characteristic with LSPM with modified asphalt, which proven that LSPM with neat asphalt can use as asphalt pavement flexible base by properly mix design and pavement structure design.
