wearing or surface course Explanation: WEARING COURSE (now referred to as SURFACE COURSE) The WEARING COURSE is the top layer of the ROAD PAVEMENT and as such is (usually, but not always) designed to be impervious to the ingress of water, have an even, (N.B. "even" NOT smooth) RUNNING SURFACE, be durable, and have a high resistance to skidding, and be chosen so as not to deform under the weight of traffic appropriate to the road. also: Wearing Course This layer provides a measure of skid resistance to the surface of the road and is able to be 'capped' or replaced when it has worn out. The term 'skid resistance' is used to describe the hardness of the aggregate used in the design mix of the material and its resistance to polishing. The wearing course also provides a weather proof seal to the underlying layers and can withstand the direct traffic loading. Materials most used are bituminous as follows: Hot rolled asphalt 10 or 14mm close graded 10 or 14mm open graded Dense tar surfacing 6mm medium graded 3mm fine graded 6mm dense 10 and 20mm pervious Friction courses Pervious (open porous asphalt) HTH Cristina |
