Reducing Pavement Costs (+ Subgrade Stabilization) KYSPR 11-419

Grants and Contracts Details


OBJECTIVES. The objectives of this project are as follows: 1. Review the current state of practice for sub grade modification of various agencies, including potential cost savings and stmctural perfomlance. 2. Evaluate, cost, constmctability, and strength of various subgrade stabilization techniques, including chemical modification, undercut with aggregate replacement, and aggregate base with geogrids. 3. Review current pavement design process to identify potential areas to refine designs to reduce overall pavement cost. 4. Develop project selection guidelines and specifications for sub grade stabilization, based on project type, and potential cost benefit.
