The most economical way of repairing superficial defects in concrete roads is to patch with fresh cement mortar but this currently involves closing the area of the highway concerned for at least four days to allow the new mortar to harden sufficiently to carry traffic. The report describes the laying and early performance of various cement-mortar patches used to repair concrete roads, carriageway of the A.59 Trunk Road at Longton, Lancashire. The patches were opened to heavy traffic of about 18,000 vehicles per day from four to thirty-six hours after laying. Ordinary Portland, rapid-hardening, and high-alumina cements were used to produce the mortars. All the patches laid were in good condition after twelve months' trafficking. (Author)
