Proof Rolling in Road Construction After the contractor finishes, we carry out proof rolling to check the strength and uniformity of the section. During this process, we observe key issues such as: - Rutting or tire marks - Cracks - Heaving - Segregation - Roller dram lines - Surface smoothness Once proof rolling is done, we also conduct a visual inspection to make sure the entire section is stable and ready for the next layer. | Injineer Shaaticadde
