SYNTHETIC RESIN TEST AREAS ALONG STATE HIGHWAY NO.4

MENTION IS MADE OF THE FACT THAT SYNTHETIC RESIN WEARING COURSES IN THE NETHERLANDS ARE IN MOST CASES SLURRIES, I.E. MIXTURES OF SYNTHETIC RESIN BINDERS AND FINE MINERAL AGGREGATES. AFTER APPLICATION, THE SLURRY IS SPREAD WITH SAND OR CRUSHED MATERIAL, USUALLY GRADED 1/3 OR 3/5 MM. IN PRACTICE THE PARTICLES SPREAD AND SOMETIMES APPEAR TO BE EXPELLED FROM THE SURFACE IN THE COURSE OF TIME. IN ORDER TO STUDY THIS PROBLEM FOR COMPARING VARIOUS SLURRIES A LARGE NUMBER OF TEST AREAS WERE CONSTRUCTED IN 1969 ALONG A MOTORWAY. PERIODICAL SKIDDING RESISTANCE AND TEXTURE DEPTH MEASUREMENTS WERE CARRIED OUT TOGETHER WITH VISUAL EXAMINATION OF THE TEST AREAS. IT IS CONCLUDED THAT LOSS OF SKIDDING RESISTANCE IS OFTEN DUE TO POLISHING OF THE AGGREGATE, WHEREAS EXPULSION OF THE GRITTED MATERIAL CAN BE CAUSED BY MISTAKES DURING APPLICATION. THE PERFORMANCE OF SLURRIES SPREAD WITH QUARTZ SAND WAS POOR. GOOD RESULTS WERE OBTAINED WITH CALCINED BAUXITE AND CORUNDUM USED AS GRITTING MATERIALS. /TRRL/
