PERFORMANCE OF BASE MATERIALS WITH LARGE SIZE AGGREGATE INCLUSION

The objective of this investigation was to study the effect of large size aggregates on the performance of base materials, and the permanent strains developed in aggregate mixes containing different proportions of large size aggregates. The study involved conducting triaxial compression tests and uniaxial confined compression tests under dynamic loading on cylindrical samples of 229 mm diameter and 457 mm height. In case of triaxial compression tests, the samples were tested at six different stress states. Uniaxial confined compression tests were performed on samples encased in hollow PVC cylinder. Six different gradations were tested. Maximum aggregate size used was 38 mm for gradations A, B, C, D, and E, and 51 mm for gradation F. All the samples were tested for 25,000 load repetitions. Effect of gradation, number of load repetitions, confining pressure, deviator stress, and percentage of material coarser than 10 mm, on the permanent axial strains was studied.
