Abstract
One of the main failures of hot mix asphalt (HMA) is fatigue cracking, which occurs due to weaknesses in the bitumen or bitumen-aggregate adhesion properties at medium temperatures. Moisture is a critical factor that can influence the fatigue performance of HMA, and this becomes even more significant when the pavement surface is exposed to contaminants such as dust or soot from vehicle exhaust. In this research, the effect of runoff with different pH levels on the performance of HMA at medium temperatures has been evaluated. Twelve types of HMA were prepared using two types of aggregate (granite and limestone), two types of bitumen (PG 64-16 and PG 58-22), and a water contamination-absorbing additive called zeolite at 2% by weight of bitumen. These mixtures were exposed to environmental conditions with pH levels of 5, 6, 7, 8, and 9. Mechanical tests, including dynamic shear rheometer on bitumen and semi-circular bending on HMA, were conducted. Additionally, the surface free energy components of bitumen and aggregate were measured using Wilhelmy plate and universal sorption device methods, respectively. The results indicate that moisture conditions, especially acidic conditions, increase the debonding energy, which reduces bitumen-aggregate adhesion and, consequently, increases the likelihood of fatigue cracking. Acidic and alkaline environmental conditions increase the bitumen's stiffness, phase angle, and fatigue parameter, thereby elevating the probability of fatigue cracking. Moreover, these conditions increase the fracture energy and toughness of the mixture, which reduces its ability to absorb stress and resist crack growth. Zeolite improves the non-polar component of bitumen, positively affecting the cohesion and adhesion resistance of the mixture. According to statistical analysis, the use of 1% and 2% zeolite significantly increases the bitumen's fatigue parameter, fracture energy, and fracture toughness of the asphalt mixture.
