Performance Monitoring of Boone County Expo Pavement Sections, (Continuation - Phase III) TR-671

项目名称：	Performance Monitoring of Boone County Expo Pavement Sections, (Continuation - Phase III) TR-671
摘要：	The primary goals of this project are to conduct performance monitoring of the test sections and assess environment impacts on the test sections for a 3-year period. Specific objectives are to assess the following: a. seasonal changes (within a year and over time) in foundation layer support conditions (strength and stiffness); b. seasonal changes (within a year and over time) in subbase layer permeability; c. seasonal temperature changes in foundation layers; d. seasonal changes in the in-ground stresses under loading; e. surface layer distresses over time; f. moisture changes in subbase and subgrade layers seasonally and over time; g. micro-mechanical changes in stabilized subgrade over time; h. seasonal water table changes; i. loss of support/erosion; and j. weather information monitoring. It is envisioned that the initial performance monitoring program will be setup for 3 years and then transition to less frequent testing for extended periods.
