An evaluation of the field and laboratory properties of lateritic gravels

This paper summarises the details of an accelerated loading trial, using the Accelerated Loading Facility (ALF), of five test sections composed of two types of lateritic gravel and constructed to two construction standards. A laboratory repeat load triaxial testing program was also conducted to complement the field evaluation. The trial was conducted under contract to the Louisiana Transport Research Centre on behalf of the US Army Corps of Engineers Waterways Experiment Station (WES). Two of the experiments were conducted in order to examine the performance of the pavements after they had been exposed to a sub-tropical summer season for about six months in an effort to determine if there had been any moisture penetration into the pavements during this period and, if so, what effect this had on performance. As a result of the trial, the Corps have revised their classification scheme which appears to be a viable scheme based on current information which is quite limited for airfield applications.
