Application of microsurfacing in repairing pavement surface rutting
Rutting that causes roughness on the surface of pavements is one of the pavements distresses that occurs mainly as a result of excessive loading on roads. The accumulation of water in rutted areas at rainy conditions results in reduced skid resistance, creating accident-risk conditions. One of the rapid and cost-effective practices in filling ruts is applying microsurfacing mixes in the rutted areas. In this research, a coarse size microsurfacing mix was designed and tested using a load wheel, a cohesiometer and wet track abrasion tests. The bitumen binders varied from 6.3% to 10% of the retained bitumen and various amounts of latex, ranging from 3 to 5%, were applied. Based on the above testing results, the optimum condition consisted of the addition of 5% SBR latex to emulsion mix containing 8.2% residual bitumen. With this formulation, the mix showed almost 50% increase in both abrasion and wheel load rutting resistance.
