Abstract:

In this study, critical mechanical properties of structural lightweight concrete were determined and utilized in the evaluation of a design of concrete pavements. Also presented are the critical mechanical properties resulting from unrestrained and restrained volume changes. Particular attention is given to compressive, direct tensile, and indirect tensile (split cylinder) strength at various ages of the concrete. The critical properties determined in this study indicate that concrete pavements can be designed with lightweight concrete and that expected performance in regard to the effects of warping stresses and pavement deflection will be better when lightweight concretes are used. However, the effects of restrained volume change of lightweight concrete on pavement performance can be detrimental if improper curing, or curing for too short a time, occurs. The need for further research into the effects of curing on lightweight concrete pavement performance is emphasized.
