Resilient Modulus Characterization of Hot Asphalt Treated Alaskan Base Course Material

In many areas of Alaska, clean, durable aggregates normally utilized for base course either require long hauls from outside, or are difficult to obtain within the project limits. Asphalt treatment is the most commonly used type of stabilization for the available lower quality materials to increase their strength thus extending their life and saving money to the state in the long run. This paper presents the resilient modulus characterization of hot asphalt treated base (HATB) course material in northern region of Alaska. Experimental studies were conducted to evaluate the resilient modulus of HATBs through repeated load triaxial tests. Effect of different stabilization levels (i.e. asphalt content) on the performance of HATB materials was investigated and a model was developed to reflect the influence of confining pressure and deviator stress on HATBs.
