摘要: Between 1986 and 1987, the Illinois Department of Transportation constructed a section 10-in. continuously reinforced concrete pavement (CRCP) containing recycled aggregate on I-57 near Effingham, Illinois. Functional structural data, including falling weight deflectometer tests, visual distress surveys, surface profiles, skid numbers were collected periodically throughout service life pavement. Falling results indicated that exhibited excellent load carrying, with an average transfer efficiency greater than 90% across transverse cracks. The prominent was longitudinal cracking, which appeared over reinforcement bars in all lanes. This abnormal cracking pattern had been noted for many years attributed to problems original tube feeding process. developed significant amount localized distresses patches its last 5 as result further deterioration longi...
