OIL TREATMENT FOR DUST CONTROL IN SASKATCHEWAN

THE HIGH PROPORTION OF UNPAVED ROADS IN SASKATCHEWAN DEMANDED AN ECONOMICAL, ADEQUATE SURFACE TREATMENT TO CONTROL DUST AND PROVIDE THE ROAD USER WITH IMPROVED RIDING QUALITY. OIL TREATMENT HAS BEEN USED FOR SEVERAL YEARS IN THIS RELATIVELY ARID AREA WHERE PRECIPITATION IS LESS THAN 20 INCHES OF RAIN. OIL TREATMENT IS DEFINED AS A VERY THIN ROAD-MIXED, BITUMINOUS SURFACING APPLIED TO AN OIL PRIMED GRAVEL SURFACED SUBGRADE. SLOW-CURING LIQUID ASPHALTS /SC-1 OR SC-2/ ARE GENERALLY USED IN CONSTRUCTING THIS ONE-INCH THICK SURFACE. THESE OIL-TREATMENT PAVEMENTS HAVE AN AVERAGE LIFE OF 3 TO 5 YEARS AND TRAFFIC VOLUMES OF 100 TO 400 VEHICLES PER DAY. THE TOTAL PAVEMENT CONSTRUCTION COST IS APPROXIMATELY 3000 DOLLARS PER MILE WITH ANNUAL MAINTENANCE COSTS RANGING FROM 100 TO 1500 DOLLARS PER MILE. SUCCESS OF THE OIL TREATMENT DEPENDS UPON THE METHOD OF CONSTRUCTION AND ON PROMPT MAINTENANCE. THE CONSTRUCTION AND MAINTENANCE PROCEDURES ARE DESCRIBED. /CGRA/
