SURFACE TREATMENTS FOR ASPHALTIC CONCRETE FOR HIGH SPEED TRAFFIC

The most generally used traffic surfacing in Australia and New Zealand is the bituminous seal coat or chip seal. Increased use of hot laid asphaltic concrete mixes as part of a heavy duty structural pavement or as a shape correction treatment has brought with it problems of high speed skid resistance under wet conditions, even when new. The accepted alternative treatments for such conditions are: A chip seal; embedment of select chips in the hot-mix surface during construction; and use of a open textured asphaltic paving mix. Experience in use of chip seals and permeable friction course surfacings is discussed with particular reference to design, construction, and subsequent performance as measured by wet skid resistance (including speed/friction gradient) and surface texture change. Recommendations are made on method of choice of treatment for most effective construction and service. /Author/
