Investigating the Effect of Using Waste Ultra-high-molecular-weight Polyethylene on the Fatigue Life of Asphalt Mixture

Abstract

One of the effective parameters in the occurrence of fatigue cracking distress is the asphalt binder properties used, which must be controlled by appropriate asphalt binder or additives. In this study, the effect of using Ultra-High-Molecular-Weight Polyethylene (UHMWPE) was investigated on the fatigue cracking potential of asphalt mixtures. Two types of aggregates, asphalt binder performance grade (PG) 64-16, and UHMWPE additive in two percent of the asphalt binder were used in this study, which were tested at two temperatures and five different stress levels. Marshall mix design and indirect tensile fatigue test (ITFT) were used to determine the optimum content of the asphalt binder and the fatigue life of asphalt mixtures, respectively. The results of this study indicated that the application of polymer additives increased the fatigue life of the asphalt mixtures. The fatigue life of specimens made with granite aggregates was longer than those made with limestone aggregates, and the increased life due to the use of UHMWPE was longer in samples made with granite aggregates. As expected, increasing in temperature and stress levels reduced the fatigue life of the asphalt mixtures. This decrease was much lower in samples made of asphalt binder modified with polymeric materials than in control samples.

Behavior of the Dynamic Modulus and Fatigue in Asphalt Mixtures with Blast Oxygen Furnace Slag and Blast Furnace Dust

“…The cylinders were divided into four groups, each group of two cylinders being subjected to test with distinct loads; in the range of 250 kPa to 350 kPa, respectively. The time until failure for each briquette tested was determined by the number of applications of load that caused the sample to break [31]. The stress in the center of the briquette was calculated with Eq.…”

“…To obtain the fatigue laws for the prediction of the fatigue life, Eq. (4), by Wöhler [30][31][32], was used.…”

A Comparison on Physical and Rheological Properties of Three Different Waste Plastic-Modified Bitumen

“…One is the substantial savings in terms of reduced costs, and the second is the cutting down of waste deposited in landfills. Thus, utilising waste plastic in asphalt modification must focus on enhancing the properties of pavement construction [9][10][11][12][13][14][15].…”

“…Thus, efficient recycling is the main solution to manage this waste issue, which is important in industrial engineering and scientific research. According to earlier studies [13][14][15][16][17][18], recycling is a crucial method that has several advantages, including saving natural resources, protecting the environment, and being cost effective. Consequently, it is important to consider the recycling industry as a vital industry in the current era.…”
