Continuously Reinforced Concrete Overlay on Trunk Road A3 at Horndean
Concrete overlays have been extensively used in the USA and Belgium to extend the lives of existing roads, a number of overlays being constructed of continuously reinforced concrete (CRC). This report describes the design, construction and early performance of a CRC overlay on the A3 road at Horndean in Hampshire, England, involving 110mm and 130mm thick sections and 7.05kg/sq. m steel reinforcement. Transverse cracking and longitudinal/reflective cracking occurred. A 5m length was replaced as a trial of repair techniques; many cracks were sealed by 'banding'. Regular inspection procedures are described.
