The Potential of Using Crack Attenuating Asphalt Mixtures in Oregon to Combat Long-term Durability Issues

Reflection pavement cracking occurs in Oregon when load-related surface level shear stress or underlaying cracks in asphalt or concrete propagate to surface. A successful approach to mitigate this problem is to construct a highly flexible thin asphalt layer underneath fresh asphalt pavement that can absorb displacement and impede cracking from propagating through and reaching the surface. While this approach has been successful in nearby states, there is no experience applying it in Oregon and this research project seeks to determine the optimum parameters (aggregate size, layer thickness, binder content, etc) for its successful application in Oregon roads.
