A Study on Plastic Cell Filled Concrete Pavement with Partial Replacement of Recycled Aggregate for Low Volume Road

Abstract

The use of natural aggregate (NA) plays a vital role in the construction of cement concrete pavements. Depletion of natural aggregate has a major impact on the environment. One among the possibility of protecting the impact on environment is with the use of concrete debris as recycle material which shall act as a partial substitute for natural aggregate in pavement construction. Improving the mechanical properties and reducing the life cycle cost of the cement concrete pavement on low volume roads is always a major challenge for the field engineers and researches. The use of plastic cell filled concrete economizes the life cycle cost of cement concrete pavement. This article aims in the evaluation of mechanical properties of a plastic cell filled concrete when partially replaced with recycled aggregate (RA). In the first stage, optimum RA was determined and was achieved as 30%. During the second stage, optimum RA was used for the preparation of plastic cell filled concrete of M20 grade. Mechanical properties like flexural strength, compressive strength, beam compression, hardness and durability properties were studies for cubes, beams and cylinders. The test results outperformed for M20 grade mix concrete prepared with partial RA and plastic cell.
