Description:	Technical memorandum Preface: The Waterways Experiment Station was authorized to conduct laboratory tests to investigate the possibilities of increasing the fluidity of asphalt mixtures and thus reduce the quantity of asphalt used in revetments by letter from the Mississippi River Commission dated 3 November 1947, subject: "Experiments with Asphalt Revetment." A comprehensive program covering all phases of the use of asphalt for river bank protection, prepared as a "Plan of Test," was approved in part by the Mississippi River Commission in November 1948. The study of "Mass Placement of Sand Asphalt" under the "Underwater Protection" phase of the Plan of Test was an approved item. Preliminary results of a few of the laboratory tests and the results of a limited program of dumping hot sand asphalt through a metal chute int0 a sump were presented in "Interim Report on Investigation of Sand-Asphalt Revetment" dated 1 July 1948. This report presents the results of all laboratory tests and therefore supersedes the interim report as far as laboratory testing is concerned.. The results of the program of dumping hot sand aspha1t mixtures in the sump were inconclusive and are not repeated in this report. The investigation was conducted by the Flexible Pavement Branch, Soils Division, Waterways Experiment Station. Experimental field work on the Mississippi River was accomplished by personnel of the floating asphalt plant of the New Orleans District. The Office of the President, Mississippi River Commission provided general over-all guidance and. assisted in planning the tests and conducting field experiments on the Mississippi River. Mr. R. M. McCrone of the Mississippi River Commission devoted considerable time to and was of material assistance in the investigation. Mr. W. K. Boyd, former chief of the Flexible Pavement Branch, was active both in the planning and conduct of the investigation. Engineers of the Waterways Experiment Station actively connected with the study were: Messrs. W. J. Turnbull, C. R. Foster, J. M. Griffith, 0. B. Ray, and E. C. Meredith. This report was prepared by Mr. Meredith.
