Abstract

When replaced with Natural aggregate, the Recycled aggregate has emerged as a major alternative to the conventional concrete in rigid pavement construction and has rapidly drawn the concrete industry attention due to its aggregate savings, energy savings and cost savings, environmental and socio-economic benefits. Recycled aggregate content has been found to be of use as part of the replacement of natural aggregate. Amidst growing awareness of natural resources, search for new material technology in the construction technology without sacrificing the quality and property of the material is the need of the day. In the above context an attempt is made, in the present study, to examine the possibility of replacing Natural aggregates by Recycled aggregates. The replaced material up to certain limits showed a very good compressive strength and concrete properties. Carrying these results to the KENPAVE software, an analysis is done on the concrete pavement of size 3.5 x 4.5; and, various stresses are found out using this software. The stresses for wheel loads of a single wheel, two wheels of a single axel, four wheels of two axels, six wheels of three axels for different positions in the slab likely corner, edge, middle for poisson’s ratio varying from 0.15 to 0.2 is analyzed. Results are tabulated and a discussion is presented on this analysis, which showed a tremendous change on replaced material.
