INTERIM REPORT: MOISTURE MOVEMENT AND MOISTURE EQUILIBRIA IN PAVEMENT SYSTEMS

The primary purpose of IHR-604 is to develop a satisfactory and realistic procedure for determining moisture movement and moisture equilibria in pavement systems and to develop procedures for utilizing this information in pavement design. The specific objectives of this interim report were to fulfill the requirements of Phase I (Development of Working Moisture Model), as follows: 1. Part 1.1 - Develop, based on environmental factors, a theoretical model for predicting moisture movement and moisture equilibria in pavement systems. 2. Part 1.2 - Validate the moisture model and if necessary refine the moisture model by means of controlled laboratory studies. 3. Part 1.3 - Prepare the interim report concerning the development of the moisture model and its validation by using laboratory data and available field data. It is expected that the findings from this research project will be helpful to those who must make decisions relating to moisture problems in pavement systems. The moisture model can be used to determine how various design modifications influence the moisture regime in a pavement system. It is anticipated that the model and related field and laboratory studies will lead to a less empirical approach for incorporating moisture effects into pavement design, construction, behavior, and performance. /FHWA/
