Abstract

Abstract

Three kinds of porous asphalt mixtures with different bitumen but same air voids were tested, the performance of asphalt mixture AC-16-Ⅰ was analyzed. It is pointed that with the increasing of 60℃ viscosity, bitumen porous asphalt mixture's performances such as compressive strength, cleavage strength, tensile strength, dynamic stability, hydraulic stability and low-temperature anti-crack ability are markedly improved, but 60℃ viscosity has less influence on permeability and anti-skid ability, the strength performances of porous asphalt are inferior to density graded asphalt mixture. The results indicate that the 60℃ viscosity of bitumen is the key index that influences the performances of porous asphalt mixture and rather than conventional asphalt, the high viscosity modified asphalt could be adopted for porous asphalt mixture.
