RIGID PAVEMENTS AND EXAMINATION OF THE REPORT OF THE TECHNICAL COMMITTEE ON CONCRETE ROADS

THE GENERAL REPORT FOR THE SESSION ON RIGID PAVEMENTS WAS PRESENTED BY DR. H. SCHNECKE OF GERMANY WHO HAD REVIEWED REPORTS FROM 13 COUNTRIES. SUBJECTS COVERED IN HRIS PRESENTATION INCLUDED: STABILZATION OF BASE COURSES, THICKNESSES OF CONCRETE SLABS, MEASUREMENT OF CONCRETE STRENGTH, STEEL REINFORCEMENT, CONSTRUCTION JOINTS, USE OF SLIP FORM PAVERS, USE OF PRESTRESSED CONCRETE, REPAIR OF CONCRETE PAVEMENTS, USE OF AIR ENTRAINING AGENTS, CONSTRUCTION AND MAINTENANCE COSTS, AND RIDING QUALITY. MR. DAVID OF GREAT BRITAIN PRESENTED THE RESULTS OF EXPERIMENTAL USE OF THE SLIP FORM PAVER. MR. SHARP, ALSO OF GREAT BRITAIN, DISCUSSED DESIGN OF REINFORCED AND UNREINFORCED CONCRETE ROADS, DISADVANTAGES OF THE USE OF EXPANSION JOINTS, INVESTIGATION OF MINIMUM MAINTENANCE ROADS, AND FINALLY, SKID RESISTANT SURFACES. DR. ITOH OF JAPAN POINTED OUT SIX WAYS IN WHICH ROAD CONSTRUCTION IN JAPAN DIFFERS FROM OTHER COUNTRIES: DESIGN APPROACHES, HIGHER STANDARDS FOR CONCRETE STRENGTH, MORE EMPHASIS ON WORKABILITY, CRACK PREVENTION BY JOINT CUTTING, CONSTRUCTION MACHINERY, AND TEMPERATURE OF CONCRETE SLABS. MR. DELLA LIBERA OF ITALY DISCUSSED DURABILITY OF CONCRETE AND INVESTIGATIONS OF IMPROVEMENTS THROUGH VARIOUS CHEMICAL ADMIXTURES. OTHER SPEAKERS INCLUDED DR. MINETTI OF GERMANY, M. REVERDY OF FRANCE, AND MR. ESCARIO OF SPAIN WHO PRESENTED THE ASPECTS OF CONCRETE PAVEMENTS MOST IMPORTANT TO THEIR COUNTRIES. DR. KIRKHAM OF GREAT BRITAIN PRESENTED THE CONCRETE ROADS COMMITTEE REPORT WHICH INCLUDED: (1) A LIST OF EXPERIMENTAL WORK ON PRESTRESSED CONCRETE AND AN ASSESSMENT OF PRESTRESSING SYSTEMS; (2) PROBLEMS OF CONSTRUCTION; (3) CONCRETE SURFACES AND RIDING QUALITY; (4) USE OF PENALTY CLAUSES IN SPECIFICATIONS; AND (5) USE OF THE SLIP FORM PAVER AND ASSOCIATED PROBLEMS. ADDITIONAL REMARKS ON PRESTRESSED CONCRETE WERE CONTRIBUTED BY DR. NAGAMORI OF JAPAN.
