Abstract
The topic has been selected to check the suitability of waste materials in road construction. This will help in getting the economy in road construction as well as saving the environment degradation in terms of reduction in mining and less air pollution. Construction of roads and highways involve huge amount of money and materials mainly aggregates. As millions tones of fresh aggregates are used in road construction and considering their scarcity, replacement of part of the fresh aggregate with waste glass and reclaimed asphalt pavement (RAP) is considered in the present study. The present study discusses the suitability and applicability of waste glass and RAP when used in blends with fresh aggregates for road construction. Performance of these blend are measured by performing various laboratory tests such compaction test and California Bearing Ratio (CBR) test. Granular Sub Base (GSB), grading-3 from the latest MORTH specification has been selected. The test results indicate that virgin aggregate can be replaced by waste glass and RAP up to 25% and 30% by weight respectively and provided satisfactory geotechnical results to be used in GSB.
