Experimental Investigation of Flexible Pavement Using Shingles

Abstract

Abstract: Huge volumes of Shingles are produced from building construction and Asbestos industries. Basically, waste Shingles Aggregates (WSA) are being produced by crushing Shingles during the process of transport and installation of roof, wall and floor. Present society are progressively moving forward to be more environment friendly. To meet up this purposes, recycling and reuse of this material can be the best alternatives than landfill disposal in respect of environment conservation and economy. To increase the usage of Shingles in pavement construction, different percentage of Shingles can be used with the natural aggregate. The technical flexibility of using waste Shingles aggregates as partial replacement of natural aggregates in bituminous mixes can be evaluated. This research work presents some of the laboratory investigation on the possible application of waste Shingles aggregates in bituminous mixes. The physical properties of coarse aggregates, fine aggregates, filler and bitumen are determined according to standard test. Marshall test specimens are prepared for testing to measure the Marshall properties. at optimum bitumen respectively are determined. According to AASHTO, Marshall stability test properties of mixes of waste shingles aggregates are satisfactory. investigated results indicate that the bituminous mixes with waste shingles aggregates give satisfactory results for construction of medium traffic road Keywords: Waste Shingles Aggregates, Marshall Mix Design, Flexible Pavement Construction
