DESIGN OF FULL-DEPTH ASPHALT PAVEMENTS WITH IN-DEPTH STRENGTH

DISENO DE PAVIMENTOS ASFALTICOS DE ESPESOR PLENO (COMPLETO) Y DE RESISTENCIA PROFUNDA

The author emphasizes the operational, structural, economic and constructional advantages of full-depth asphalt pavements: they prevent water from accumulating on the subgrade forming pockets that impair the strength of the pavement. They eliminate the need for underground drainage. They reduce the need for highly-selected granular materials. Construction time decreases. Delays due to bad weather such as rain, low temperature and wind are reduced to a minimum. They allow stage construction for it is possible to use the road before the laying of the wearing course thus enabling observations to be made and obtaining an earlier return from the investment. As full-depth asphalt pavements are thinner than other structures they cause less damage to services in streets. Details are given of the Asphalt Institute design method for determining the overall thickness of the bituminous mixture as a function of traffic analysis and subgrade strength measured with the CBR test, plate bearing test or hveem stabilometer. The design method provides for stage construction and offers two design procedures depending on whether the thickness of the surfacing or construction time is determined in the first phase of the project.
