Improved Drainage and Frost Action Criteria for New Jersey Pavement Design. Volume 2. Experimental Subsurface Drainage Applications

摘要

This Volume II report of a three volume series in conjunction with guides, supplements and technical notes, describes a concerted effort to resolve the problems of internal (subsurface) road drainage. The objective of the research was to formulate the design methods and the construction and maintenance procedures for such a drainage system. In this report the results of test track evaluations of reduced scale pavement sections having underdrainage elements are summarized. The field experience of constructing two experimental internally drained highway sections is also given. A long-term monitoring program has been instituted for these trial installations; the monitoring plan and baseline measurements are provided. Finally, from the results of the model tests, field trials and previously reported laboratory investigations, construction requirements for the proposed highway underdrainage system are discussed.
