Crumb Rubber Modified Crushed Stone–Crusher Dust Gradation Mixes as Base Course Material

Abstract: Bulk utilization of crusher dust requires experimentation to suit as construction material. Inherently crusher dust has characteristics similar to sand can be identified as an alternative. In the present investigation crushed stone and crusher dust were used to prepare gradations. In accordance with MORTH by limiting their sizes to 26.5 mm. These were further exposed to tire chips of sizes(square) 10mm-4.75mm in partial replacement to the corresponding sizes of crushed stone and subjected for tests like compaction and CBR. Test results showed improvements in CBR values which are 80%. Addition of 1.5 to 2% of tire chips with CBR values greater than 80% can be used as Base course material in flexible pavement construction.
