Abstract
A porous asphalt mix was designed with high viscosity modified bitumen and rubber bitumen at an aimed air void content of 20%. A Hamburg wheel tracking device was employed to test rutting potentials in both 60°C air bath and 40°C water bath conditions. Triaxial compression tests and triaxial cyclic compression tests were performed to determine the resistance to shear stress and permanent deformation at 60°C. The study results show that despite the similar rheological behavior between rubber bitumen and high viscosity modified bitumen, rubber bitumen is far less applicable than high viscosity modified bitumen in the aspect of high temperature performance and shear resistance. However, the rubber asphalt mixture shows a longer creeping stage and a stiffer resilient modulus in cyclic loading and lower level. Under the conditions defined herein, porous asphalt made with rubber bitumen can only be used for lighter volume of traffic
