Review on Trend Evaluation between Marshall Stability and I.T.S. Values for D.B.M. using various Binders with Waste Plastic

Abstract: The pavement designer must be concerned about the most important effects of the road pavement, among them cracking, rutting, displacement fatigue, and distortion. The Marshall stability test is used to measure the strength under compressive load of the bituminous mix simulating rounded wheel shape, while the indirect tensile strength test is used for estimating the tensile property of the mix. It is known that incorporating waste plastic judiciously leads to improvement in mix properties e.g. Stability and Moisture Susceptibility. However, it need to be seen that it might not have a negative impact on the DBM mix's tensile properties. There is need to get insights as whether the I.T.S. values shall also be optimum at the binder content which provides maximum Stability. There have been many research studies conducted on Marshall stability and Indirect Tensile Strength tests separately, as well as a few number conducted in simultaneously. However, no single research has been performed in combination for DBM incorporating waste plastic utilizing various Grade binder. Hence a study may be undertaken to look at the trend evaluation between these two parameters. This research shall assess the trend between Marshall stability and Indirect Tensile Strength values for DBM Grade-II using VG-30 and VG-40 grade binder with or without waste plastic and clarify whether it is appropriate for the mix design. The pavement designer will benefit significantly from this study's wealth of knowledge in order to perform both tests
