LAYING AND COMPACTING ASPHALT TECHNIQUES IMPROVED
******
RECENT IMPROVEMENTS IN LAYING AND COMPACTING ASPHALT BY THE PUBLIC WORKS DEPARTMENT HAVE PRODUCED BETTER ROAD SURFACES IN A NUMBER OF AREAS IN HONG KONG.
LAST YEAR A SKILLED ROAD SURFACING SUPERVISOR WAS RECRUITED TO INSTRUCT AND TRAIN HONG KONG OPERATIVES, A SPOKESMAN FOR THE DEPARTMENT SAID TODAY (MONDAY).
+A TEAM OF ROAD OPERATIVES, WHICH WAS THEN TRAINED, WAS INSTRUMENTAL LAST YEAR IN INTRODUCING IMPROVED ASPHALT LAYING TECHNIQUES.
+OWING TO BETTER WORKMANSHIP, CO-ORDINATION, MECHANICAL PLANT OPERATION, AND SITE SUPERVISION, THE SURFACES PAVED BY THIS PWD TEAM HAVE BEEN FOUND TO BE SUPERIOR TO THOSE LAID UNDER FORMER ROAD RESURFACING PROGRAMMES,+
THE SPOKESMAN ADDED IT WAS QUITE OBVIOUS THE TRAINED TEAM WAS ABLE TO ACHIEVE, BY THEIR METHODS, IMPROVEMENTS IN THE RIDING QUALITY (UNIFORMLY EVEN SURFACE) + OF THE ROADS, ROAD LIFE, AND COMPACTION OF RESURFACING MATERIALS.
ALSO, A GREATER AREA WAS RESURFACED IN KOWLOON →→ ABOUT 120,000 SQUARE METRES IN 1978 COMPARED WITH 59,000 SQUARE METRES IN 1977.
+AMONG OTHER TECHNICAL IMPROVEMENTS NOTICED IN THE ROADS HAVE BEEN BETTER FORMING OF CENTRE JOINTS, 'EDGE SEAL ING', AND MAINTENANCE OF PROPER LAYER THICKNESSES, THE SPOKESMAN COMMENTED.
THERE ARE ABOUT 750 KILOMETRES OF FLEXIBLE CONSTRUCTION+ ROADS IN THE TERRITORY THOSE FINISHED WITH BITUMINOUS METALS, PUT NOT IN CONCRETE.
