Abstract

Though flyash has been used as a fill material and stabilizing material in road construction, studies on its use in bulk quantity for construction structural layers (i.e. subbase and base) are very limited. In the present study, an attempt has been made to use flyash and stone dust mixture (70:30 ratio) and stabilized with cement as a structural layer material for use in rural road pavements. To address the brittleness of the stabilized material, polypropylene fibers were also added as reinforcing material. Mechanical properties of the stabilized material, in terms of unconfined compressive strength, flexural strength, indirect tensile strength, flexural modulus (Eflx), Poisson’s ratio (µ) were evaluated to assess the suitability of the material. Durability tests were also conducted on the samples to meet the specifications. Results indicate that, cement stabilized flyash-stonedust mix can be suitably used for construction of subbase and base layers of rural road pavements.
