Investigating thermal cracking potential of Ontario RAP-HMA mixtures

Thermal cracking on flexible pavements poses serious concerns in cold-regions of the world, especially in Canada. Influenced by temperature changes, thermal cracks are known to initiate other forms of pavement deterioration. The prevention of thermal cracks would guarantee better performance of roads built with asphalt concrete mixtures. Recognizing asphalt recycling as a key sustainable practice in the pavement industry, this paper examines …
