The Impact of Aging on Water and Frost Resistance of Asphalt Concrete with Low –Temperature Bitumen

This paper has proven that the application of low – viscosity (low – temperature) bitumen in asphalt concrete results in an improvement in its mechanical properties (Marshall stability and deformation, static creep modulus and indirect tensile strength) in comparison to traditional bitumen. The tests conducted with the procedures long term aging (LTOA) and short term aging (STIA) according to the Strategic Highway Research Program (SHRP) methodology prove that the use of low – temperature bitumen results in slowing down the aging process of asphalt concrete and the dynamics of this process is lower than in case of traditional bitumen. The measurements of water and frost resistance (according to AASHTO T283) of asphalt concrete and of its resistance to low – temperature cracking (according to PANK 4303) have showed that the use of low – temperature bitumen results in higher resistance to these climatic factors than in case of the application of the road bitumen 35/50 as a binder.
