Abstract

The findings of short term oven ageing and long term oven ageing of porous asphalt mixes sample incorporating conventional binder 60/70 are presented in this study. Oven ageing is a set of procedures to simulate the deterioration on asphalt pavements equivalent to 10-15 years in service. Samples were subjected to short term and long term ageing according to AASHTO R30-02 (AASHTO, 2002) procedure. As a result, the permeability, tensile strength and resilient modulus of short term and long term aged specimens were found to be higher than un-aged specimen. Normally, the coefficient of permeability decreases as the binder content increased. Generally, Short term mixture exhibits 21.18% to 33.24% higher permeability compare to un-aged and 54.63% to 73.99% compared to long term ageing.
