PERFORMANCE OF PCC PAVEMENTS IN CALIFORNIA

A rating system based on present serviceability index (PSI) was used to rate and periodically rerate some 130 individual concrete saving projects of various ages. Indications are that many of the pavements will last 30 years or longer, but a few will fail in less than 20 years. Average ratings of new pavements, based on 20 projects, was about 4.3 PSI, which was disappointingly low. Discussed in the report are various features affecting pavement performance, such as joints, cracks, and surface texture. An end result type specification for weakened plane joints, which has been successfully implemented on several projects, is included.
