RUTTING--HOW SERIOUS IS THE PROBLEM? HIGHWAY SUBCOMMITTEE ON CONSTRUCTION OF THE STANDING COMMITTEE ON HIGHWAYS

To assess the degree of pavement rutting, AASHTO sent a questionnaire to all 50 U.S. states, U.S. territories and Canada. Responses from 48 states, one territory, and four Canadian provinces show that rutting is a significant problem and that the various agencies cite multiple causes for rutting and have implemented changes in their asphalt pavement policies to decrease premature rutting. Some preventive measures cited include designing highway pavements in accordance with the types of loads they will have to carry, using quality aggregates, and monitoring construction projects to make certain of adherence to quality aggregate and asphalt specifications. Specific percentages and measurements are also given.
