Investigation of Cold Regions Dense Graded HMAC (EME) Sensitivity to Bitumen and Filler Content
High modulus asphalt concretes (HMACs), enrobés à module élevé (EMEs) in French, improve asphalt pavement durability due to their high rigidity, high resistance to rutting and fatigue and in some cases very good low-temperature behaviour. The goal of the current study is to perform a sensitivity analysis of HMAC (EME) developed specifically for cold regions. This sensitivity study is based on laboratory experimentation. From the control mix, four bituminous mixes were tested according to a two-level full-factorial experimental design, thus varying amounts of bitumen and filler according to the most critical cases that may occur in the plant and allowed by quality standard. Stiffness, low temperature, and rutting resistance were investigated in the current study. The results show that a variation of the bitumen content will not significantly affect the stiffness, the rutting resistance and the low temperature cracking of HMAC mixes. Moreover, the results show that the filler content does not have a significant impact on the measured properties. HMAC studied appears very promising from a manufacturing point of view since it does not require more attention during the manufacturing process than conventional hot mix asphalt (HMA).
