Synopsis

Rutting is caused due to continuous traffic loading which is a type of common pavement distress. The presence of moisture reduced rut resistance of bituminous mixture as they alter the bond strength of aggregate with bitumen. The minerals present in the moisture also enhances the moisture damage of the flexible pavement. Therefore, this study inquires to judge the effects of liquid in the empty out attitude of bituminous factual, ultimate coarse tiring coat used in India. The rut test was performed using the wheel rut tester after moisture conditioning. The moisture induced stress tester is used to condition the samples. A considerable reduction of rut resistance in the moisture conditioned samples was observed compared to control mix.
