N.R.B. EXPERIMENTAL PROJECT: SEALING OF SHOULDERS

A CONTROLLED EXPERIMENT IS TO BE CONDUCTED BY THE NATIONAL ROADS BOARD TO EVALUATE THE COSTS AND BENEFITS OF SEALED SHOULDERS. THE POINTS MADE IN FAVOR OF SEALING HIGHWAY SHOULDERS ARE IMPROVEMENT OF SAFETY AND SERVICE BY: REMOVAL OF THE RUT THAT TENDS TO FORM ON METALLED SHOULDERS AT THE EDGE OF THE SEALED TRAFFIC LANE, REDUCTION OF ACCIDENTS CAUSED BY FLYING STONES, WANDERING VEHICLES SKIDDING ON THE SHOULDER, AND BY ENCOURAGING VEHICLES TO RUN CLOSER TO THE LEFT. MAINTENANCE COSTS SHOULD BE REDUCED BY ELIMINATION OF EDGE OF SEAL BREAKS, REDUCTION OF SHOULDER DRESSING AND GRADING AND REDUCTION OF NEED TO CLEAR WATER TABLES OF SILT AND SHOULDER EROSION DEBRIS.
