Characteristics of Polymer Modified Reclaimed Bitumen and Aggregate as a Sustainable Pavement Material

Infrastructure development in a country depends on the development of road network. In a developing country like India construction of pavements forms the integral part of infrastructure development. The most common material used for the construction of pavements is hot mix asphalt (HMA). The demand for this material is very high and at the same time due to maintenance of pavements lot of used paving material is wasted. This paper deals with the characteristics of reusing the reclaimed materials as construction materials in the construction of pavements. Experimental investigations were conducted to study the properties of aggregate and bitumen that are reclaimed. The test results on the reclaimed material were conducted and it was found to be suitable to be reused for the pavement construction. Systematic proportioning of the reclaimed material with the virgin material was investigated and the results show that the reclaimed materials performed equally well as the virgin material. The cost analysis for using these recycled materials is also calculated, in order to highlight the advantage of using the recycled material.
