Chip seal is one of the most common and cost-effective maintenance treatment approaches to improve the life-time of pavements. Recently, the research team developed a rubberized chip seal where natural aggregate is replaced with crumb rubber obtained from recycled tires. During this study, chip seal specimens with crumb rubber and mineral aggregate were designed and constructed according to three different common methods including McLeod, Kearby, and modified Kearby.
The macrotexture of the laboratory specimens was investigated using the sand patch and image processing methods to show how each reflects on the skid resistance. The values of the mean texture depth …
