ENVIRONMENTAL FACTOR DETERMINATION FROM IN-PLACE TEMPERATURE AND MOISTURE MEASUREMENTS UNDER ARIZONA PAVEMENTS
Arizona at present uses the AASHTO Interim Guide equations to determine thickness of structural layers (flexible and rigid) in the highway prism. Inputs to these equations are based on past experience and have been empirically developed. In the future Arizona intends to adopt a systems approach to design of both flexible and rigid pavements. As such several inputs including traffic, environment, construction, structural and maintenance will be needed. The long term (3-5 years) objective of this study is to quantify the environmental inputs and relate them to highway performance. The purpose of this phase of the study was to develop, test and install the sensors and instrumentation to implement a program to monitor moisture and temperature changes in and under the highway.
