These systems do not account for the pavement’s deterioration rates. For instance, two pavement sections rated fair this year may or may not have similar ratings next year. A balanced and comprehensive system for rating pavement condition should be based on the pavement’s conditions, distresses, and deterioration rates. In a research study sponsored by FHWA, dual systems of rating pavement condition were developed on the basis of the pavement’s functional and structural aspects and rates of deterioration. These rating systems account for current and future pavement conditions and distresses. Therefore, the systems provide more accurate information to decision makers about management of the pavement network while being simple enough for communication with legislators and the general public. The functional rating is based on ride quality (international roughness index) and safety (skid resistance and rutting) and is expressed by the remaining functional period (RFP). The structural rating is based on cracking, faulting, and rutting and is expressed by the remaining structural period (RSP). The RFP is defined by the shortest time in years between now and the year when one of the conditions reaches its threshold value. Similarly, the RSP is the shortest period in years between now and when a threshold is reached. The main advantage of the RFP and RSP is that both are proportional to the elapsed time. Their values decrease by 1 year for each calendar year.
