NEW CRCP SHOULDERS BEEF UP OLD I-STATE

Texas is replacing old asphalt shoulders along its roads with continuously reinforced concrete pavement (CRCP). The shoulders will be tied to the CRC mainline pavements, thus preventing surface runoff draining through the joint between the pavement and its shoulder, as is now the case. It is expected that the CRCP shoulders will decrease road maintenance efforts and costs, and strengthen and extend the life of the old CRC pavements. This article discusses one of the latest such projects, a $6.4 million, 16.9-mile job near Gordon, 70 miles west of Forth Worth. The 16-month job started in late 1988 and was completed ahead of schedule this fall (1989). Only the 10-ft-wide outer shoulders were replaced by a 4-in.-thick asphalt base and 8 in. of CRCP tied to the 20-year-old mainline slabs. A total of 223,000 sq yd of CRCP was placed. The five-step procedure is outlined, with information provided on the construction equipment that was utilized.
