Abstract:
The aim of the research work is to test the feasibility of use of RAP aggregate for improving properties of GSB (granular sub-base) mixes. The main objectives of the research work are to determine the properties of materials namely fresh aggregate, Reclaimed Asphalt Pavement aggregate and stone dust used in the study, To determine the maximum dry density (MDD), optimum moisture content (OMC) and CBR value of the GSB mixes with fresh aggregate and RAP aggregate, To determine the permeability of the GSB mixes with fresh aggregate and RAP aggregate, To study the effect of replacement of fresh aggregate with RAP aggregate in varying proportion of 0% to 70% with increment of 10% on compaction and strength characteristics of the GSB mixes, To develop relationships between strength and compaction characteristics of GSB mixes with proportion of RAP.
Study on the Utilization of Reclaimed Asphalt Pavement aggregate for road construction can be an effective and cost efficient method. It reduces the disposal problem caused by construction waste and also helps to conserve natural aggregate. The study has been taken up mainly to understand the feasibility of use of RAP aggregate for construction of granular sub base. In this study, fresh aggregate was replaced with Reclaimed Asphalt Pavement aggregate in various proportions, 0%, 10%, 20%, 30%, 40%, 50%, 60% and 70%, for testing the compaction, strength and permeability characteristics of the GSB mixes. The results of the study are applicable only to the materials used and specified characteristics studied in this work. However, the methodology can be applied to other similar materials as well and the expected results may also be similar and compatible.
