Use of Recycled Aggregate in the Construction of Low Strength Rural Rigid Pavements (original) (raw)
In today's world due to the rapid industrialization, recycled aggregates play an important role in the construction activities for the preservance of natural aggregates. The study is to determine the suitability of recycled aggregates for the construction of rural roads, which will in achieving the economy for the road construction and also helps in protecting environment degradation in terms reducing the mining and pollution. For the construction of rural roads requires large quantity of fresh aggregates, replacement of fresh aggregates by recycled aggregates is considered in this study. In this project recycled aggregates were collected from the demolished building from chamarajpet, Bangalore. Various tests were conducted on coarse and fine aggregates. Grade of the concrete used is M30. Compression, flexural and split tensile tests has been carried out and compared the test results with the prepared control mix. Also the rigid pavement analysis has been carried out in FEM based KENPAVE software. Variation of middle, edge and corner stress is found for the different slab thickness. For the analysis single axle with single wheel and dual wheel are considered.
