Between 1986 and 1987, the Illinois Department of Transportation constructed a section of 10-in. continuously reinforced concrete pavement (CRCP) containing recycled concrete aggregate on I-57 near Effingham, Illinois. Functional and structural data, including falling weight deflectometer tests, visual distress surveys, surface profiles, and skid numbers were collected periodically throughout the service life of the pavement. Falling weight deflectometer results indicated that the pavement section exhibited excellent load carrying, with an average load transfer efficiency greater than 90% across the transverse cracks. The prominent distress was longitudinal cracking, which appeared over the reinforcement bars in all lanes. This abnormal cracking pattern had been noted for many years and had been attributed to problems with the original tube feeding process. The section developed a significant amount of localized distresses and patches over its last 5 years as a result of further deterioration of the longitudinal cracking. A petrographic examination concluded that no deleterious alkali-silica reaction had occurred in the pavement and that the air void system had been normal. The mean transverse crack spacing was approximately 1.5 ft, which was significantly shorter than normal CRCP and was attributed to the greater drying shrinkage potential of recycled concrete aggregate. Functionally, the pavement showed good skid resistance and fair-to-good ride quality. The overall performance of this CRCP section exceeded the performance of roughly 50% of the 10-in. CRCP within Illinois in terms of age and 25% in terms of traffic. In June 2010, this CRCP section was overlaid with 3.5 in. of asphalt concrete.
