Asphaltic concrete overlays on surface-treated pavements with lateritic gravel bases
AbstractThe design and performance of asphaltic concrete overlays for surface-treated pavements with lateritic gravel bases and subbases using the results of Benkelman beam deflection measurements are discussed. It is found that failure to consider pavement distress factors, local materials and environmental conditions in design are inadequate and early signs of distress are exhibited. It is concluded that the high percentage of unpredictable generated traffic is an important contributing factor to performance. An assessment of stress interaction between the existing surface-treated pavement with granular bases and subbases and the asphaltic concrete overlay needs to be considered in the design process. An appropriate approach would be to consider the overlay design as a new asphaltic concrete-surfaced pavement with granular base and subbase.
