Final Report of the Working Party on the Slippage of Rolled-Asphalt Wearing Course
A slippage failure is associated with the presence of a plane of weakness at or near the bottom of the wearing course. The present report confirms the important part played by the stiffness of the road structure in the development of such a plane; it recommends that the stiffness should be improved by making every effort to protect the subgrade during construction from the effects of moisture and from undue disturbance by construction traffic and by ensuring the structural adequacy of the unbound granular materials in the pavement. The rolling of the asphalt wearing course at too high a temperature is another factor that increases the risk of developing a plane of weakness, and a range of temperatures during laying is recommended. Whenever possible, wearing courses should not be laid on basecourses at temperatures close to freezing point. (Copyright (c) Crown Copyright 1979.)
