Investigation of the Design and Control of Asphalt Paving Mixtures: Volume 1

Date: May 1948
Creator: Waterways Experiment Station (U.S.)
Description: "This report presents the results of laboratory and field tests conducted by the Corps of Engineers to develop a method for the design and construction control of asphalt paving mixtures. The investigation consisted of: (a) the selection of a test apparatus and the performance of laboratory studies to develop techniques and procedures; (b) the construction of a test section and the performance of traffic tests with 15,000 and 37,000-lb single and 60,000-lb dual wheel loads to obtain design criteria; and (c) additional laboratory work to adjust the test procedures to the design criteria" (p. 1).
