Title: EVALUATION OF DUNE SAND AND ASPHALT MIXES CONTAINING DIFFERENT AMOUNTS OF CRUSHER WASTE DUST

Availability: Find a library where document is available Abstract: An attempt was made to characterize the dune sand and asphalt mixes containing crusher waste dust. Dune sand and asphalt mixes were found to be weak, easily deformable, and to contain a considerable amount of air voids. The optimum asphalt content from results of Marshall stability and split tensile strength tests was about 12% by weight of sand. The properties of such mixes were improved to a great extent by introducing crusher waste dust into the blend. Five percentages of dust by weight of dune sand were used; namely, 10, 20, 30, 40, and 50%. Not only the content of air voids and the optimum asphalt content were reduced by the dust, but also the stability, split tensile strength, and resilient modulus were significantly increased. The modified sand mixes that were developed have a great potential for being used in low- or medium-volume roads, particularly in areas where good-quality aggregate is scarce and dune sands are abundant.
