A SURVEY OF ROADS CONSTRUCTED WITH LEAN CONCRETE BASES- SECOND REPORT
DETAILS ARE GIVEN OF INSPECTIONS OF 33 ROADS IN ENGLAND AND WALES WHERE LEAN CONCRETE BASES HAVE BEEN USED. THE DEFECTS OBSERVED COMPRISED TRANSVERSE CRACKS, BELIEVED TO BE CAUSED INITIALLY BY THERMAL AND POSSIBLY MOISTURE MOVEMENT AND DEFECTS SUCH AS DEFORMATION AND CRAZING WHICH MAY BE ATTRIBUTED TO THE ACTION OF TRAFFIC. REPAIRS AND RESURFACINGS WERE ALSO RECORDED. IN GENERAL THE FREQUENCY OF TRANSVERSE CRACKS HAS INCREASED AND ALSO THE INCIDENCE OF OTHER DEFECTS SUCH AS DEFORMATION AND CRAZING. PROBLEMS ASSOCIATED WITH THIS SURVEY ARE DISCUSSED AND PROPOSALS FOR FUTURE WORK OUTLINED. /RRL/
