Utilization of old asphalt road waste for high bending strength concrete flooring tile product to reduce environment impact

Abstract

The objective of this research is to develop the concrete flooring tile product from old asphalt road waste. The 6 ratios of Portland cement type1: coarse sand: old asphalt road waste: water reducer type A: tap water were designed including: 1: 5: 0: 0.02: 0.4, 1: 4.5: 0.5: 0.02: 0.4, 1: 4: 1: 0.02: 0.4, 1: 3.5: 1.5: 0.02: 0.4, 1: 3: 2: 0.02: 0.4, and 1: 2.5: 2.5: 0.02: 0.4 by weight. The concrete flooring tile casted with the compressive machine. The property tests followed the TIS.378 - 1988 (concrete flooring tiles). According to the result, it was found that the 1: 2.5: 2.5: 0.02: 0.4 was the proper ratio of the concrete flooring tile. The increasing of old asphalt road waste in concrete flooring tile effected to decrease the water absorption and thermal conductivity properties. In term of the density and bending strength properties, there were not many differences. The developed concrete flooring tile product from old asphalt road waste can use as same as the common concrete flooring tile product in market.
