Title

Investigation Into Use of Waste Materials in Pavement Subbase

Abstract

With enormous construction activities taking place, scarcity of high quality quarry aggregates has resulted into significant concern for researchers and engineers in the world of different countries including India. This results into urgency for finding out sustainable, viable alternative materials which could be considered as partial replacement to natural aggregates. Waste generated from construction and demolition waste (C & D waste) constituent major portion of landfills and if not recycled in proper way can significantly affect the environment. With aim of achieving reduction in demand of virgin aggregates or natural aggregates, significant efforts have been made to incorporate these waste materials generated and occurred from C & D waste and use them as alternatives to naturally available aggregates; as usage of these materials resulted into significant environmental benefits. In the present study, in order to evaluate their potential reuse as in highway sub base or base material, an attempt is made with extensive series of laboratory tests carried out on these materials included recycled concrete crushed aggregates (RCA/CCA) and Reclaimed Asphalt Pavement (RAP). Different blended mixture of virgin aggregates/ RAP+RCA were prepared with proportions of 100/0, 90/10, 80/20, 70/30 and 60/40 respectively. Also, in addition to these mixture, another set of samples prepared by replacing natural aggregates by 20% and 40% with two different moorum samples. Physical, compaction and CBR test were conducted on all of the samples. Results obtained indicated that for different sample prepared with NA/RAP+RCA Mixtures shown gradual decrease in water content and CBR values with increase in % replacement. Another blend mixes prepared with moorum samples yielded lower strength as compared with another samples containing RAP and RCA, still showing satisfactory performance and can be used as in pavement sub base applications.
