Abstract:

Many miles of pavements in Texas arc constructed with aggregate bases. These pavements are typically comprised of a thin asphalt surface over a flexible or aggregate base layer. The base layer is, therefore, usually the primary structural layer. Thermal-and moisture-related effects can cause cracks and general distress within these layers, resulting in a general reduction in the serviceability and load-carrying capacity of the pavement. The cracks that may emanate from the flexible base will reflect through the hot mix asphalt surface and further compromise load-carrying capacity of the pavement. The complex and diverse environment within Texas provides a challenge to the proper design, construction, and maintenance of aggregate bases. This project identifies a simple and easy-to-use dielectric value measurement test as an aggregate is subjected to capillary soak as a primary tool for design and construction of acceptable bases.
