Abstract

In this study different mechanical, physical and durability tests were manufactured to investigate the effect of recycled rubber as a partial replacement of fine aggregate by volume on the properties of plain concrete pavements (PC). First step of this paper, the slump, flexural and compression tests are carried out for trial batches to choose airfield PC mix. The second step, the slump, flexural and compression tests are carried out to select the optimum percentage of rubber as a partial replacement of fine aggregate by volume. Afterward, the tests of slump, compression, three point bending of single edge notched beam, splitting, flexural, impact, ultrasonic pulse velocity, Schmidt hammer, electric resistivity, water absorption and abrasion resistance were performed. Results of the experimental study indicated that the addition of rubber recorded significant to slight improvement in the mechanical, some physical and some durability properties of PC. Slight reduction in other properties of PC was observed.
