Abstract
To enhance the performance of mix granulate road base courses by cement treatment. The mechanical properties of cement treated mix granulate (CTMG) were studied, which was designed with 65% crushed masonry and 35% crushed concrete by mass. The central composite design was employed to prepare specimens with different levels of cement content and degree of compaction. All specimens were cured in a fog room at 20°C for a specific number of days. The compressive strength and the indirect tensile strength were determined through the monotonic compression and indirect tension tests. Effective prediction models for the mechanical properties of CTMG, in relation to the cement content, the degree of compaction and the curing time, were successfully established for a mix containing 65% crushed masonry and 35% crushed concrete by mass.
