Comparative Study of the Laboratory Performance of Hot Mix Asphalt with 10 Percent Glass Aggregates
A major research project is going on at the Laboratoire des Chaussées et Matériaux Bitumineux (LCMB) of École de Technologie Supérieure (ETS) regarding the use of glass aggregates in asphalt mixtures. This paper focuses on the use of glass aggregates in an ESG10 asphalt mixture used as a wearing course. The objective of this study was to select the optimal binder content for a 10 persent glass content asphalt mixture. Overall, a total of four asphalt mixtures were tested, one reference mixture and three mixtures with 10 persent glass and different binder content. For all asphalt mixtures, performance was evaluated using teh following three criteria: 1) compaction ability with teh Superpave gyratory compactor; 2) rutting resistance with teh MLPC rutting tester, and; 3) complex modulus with cyclic traction-compression loading. Experimental test results performed with glass asphalt mixture with lower effective binder content than the LC mix design method criteria showed better performance than the reference mixture with respect to rutting resistance. Moreover, complex modulus test results show that reducing the effective binder content has no negative effect on the mixture behaviour in the small strain domain. Overall, the optimal binder content for an ESG10 with 10 percent glass was found. This mixture will be used in a trial section.
