초록

A thin-bonded CRCO (Continuously Reinforced Concrete Overlay) on a JCO (Jointed Concrete Overlay) was constructed at Seo Hae Ahn Express Highway in Korea. This project includes two experimental sections: 1) a JCO with saw-cut joints over existing transverse joints, and 2) a CRCO, which employs transverse and longitudinal steel reinforcing rods, that is placed on top of an existing JCO. After milling 5 cm off the top of the JCO, an overlay thickness of 10 cm remains. Several VWSGs (Vibrating Wire Strain Gauges) were installed to evaluate curling, delamination behavior, and crack propagation of the thin-bonded CRCO. This paper describes the early behavior of this overlay and compares the current and new rehabilitation methods available in Korea. © 2009 ASCE.
