CONNECTICUT LONG-TERM PAVEMENT PERFORMANCE STUDY - FINAL REPORT

Up to ten years of monitoring for pavement distress, roughness and skid resistance was performed at 87 in-service pavements in Connecticut between 1984 and 1993. This report analyzes and summarizes the effects of pavement type, age, pavement and base thickness, traffic volume, environment, and crack sealing on the service life of flexible pavements as measured strictly by cracking. Roughness data measured with response-type roughness vehicles although presented are not analyzed, due to excessive variations from year-to-year. A summarization of skid resistance is included. A stepwise regression analysis showed surface age to be the most significant variable affecting the development of cracking. Other variables having significance include surface drainage, pavement category or structure type and thickness. It was also found that due to the subjectivity of the pavement distress rating procedure, some of the raters proved to be a significant variable in the analysis of the crack development.
