The Indiana State Highway Commission uses subjective sufficiency ratings to determine highway needs. The research was initiated for the purpose of improving upon this and it had two specific objectives. (1) To set up a method of describing pavement performance in terms of measurements using the roadmeter, Dynaflect and skid tester and (2) To set up guidelines for a methodology for an on-going evaluation of pavement performance. In-service pavements including flexible, overlay, jointed reinforced concrete and continuously reinforced concrete pavements were evaluated. Ninety-four test sections, each 1 kilometer long, were evaluated for the pavement serviceability studies. Forty-six test sections were selected for deflection and skid studies. Present serviceability index (PSI) models were developed which relate PSR with roadmeter ratings alone, and with roadmeter measurements in combination with cracking, patching and other factors related to the pavement. Deflection studies have indicated that edge deflections should be used for overlay design. Various models were developed which permit estimation of spring deflections using fall deflections. Recommendations have been made for developing a pavement evaluation system. The system will work at two levels, (1) total network and (2) individual project level.
