Ji-Wan Jang, Iwao Iwasaki Develops a method for field tests using electrochemical measurements so that the effectiveness of chemical additives selected from the laboratory tests may be evaluated in the field. Ji-Wan Jang, Iwao Iwasaki Evaluates the effect of chemical additives, designed to inhibit the corrosive effect of salt on rebars, on Portland Cement Concrete. Mary Stroup-Gardiner, Brian Wiekle, Andrew Drescher, David E. Newcomb Evaluates the use of roofing waste generated by manufacturers and from reconstruction projects. David E. Newcomb Identifies one or more suitable test methods for evaluating the viscoelastic characters of asphalt concrete. Henry Gillis, John Zollars Evaluates wear characteristics of five types of cutting edges, both Motor Patrol and Snowplow, used in gravel road maintenance.
Procedure requires soil identification, traffic counts and rational judgement.
Includes information on the use of U.S. Forest Service Aggregate Surface Design Guide and on compaction, drainage frost action, geosynthetic use and lime stabilization, as well as sample problems based on Soil Factor and U.S. Forest Service design methods. Curt Turgeon Investigates one method to improve cold temperature performance of asphalt concrete pavements by modifying the asphalt binder with ground reclaimed automobile and truck tire rubber. Evaluates crack counting, resilient modulus, inplace air voids, rutting, roughness, recovered penetration and cost considerations.
