A New Approach for Upgrading Gravel Roads to a Low Volume Sealed Standard Based on the Use of the Dynamic Cone Penetrometer
Abstract
This presentation summary outlines the successful design of light pavement structures in the Southern African region. These are simple and cost-effective, though this design often results in the need to rip and re-compact or to import a single layer of appropriate material. They do offer the possibility of economically upgrading a significantly greater length of road than conventional pavement design techniques without significantly different risk. These structures allow the designer to use local knowledge and experience, in developing appropriate layer strength diagrams for different traffic classes and environmental conditions, to optimize pavement layer thicknesses and material strengths.
