Trafficability of Soils: A Summary of Trafficability Studies Through 1955

Date: December 1956
Creator: Waterways Experiment Station (U.S.)
Description: Summary of trafficability studies conducted by the Waterways Experiment Station. It includes information about phase I tests related to "Soil Classification and Trafficability Data" as a sub-project of "Trafficability of Soils as Related to the Mobility of Military Vehicles" (published 1947-1955). It also includes initial results of phase II, "Soils Trafficability Predictions."

Trafficability of Soils: Eighteenth Supplement, Development of Revised Mobility Index Formula for Self-Propelled Wheeled Vehicles in Fine-Grained Soils

Trafficability of Soils: Eighteenth Supplement, Development of Revised Mobility Index Formula for Self-Propelled Wheeled Vehicles in Fine-Grained Soils

Date: March 1968
Creator: Kennedy, James Garland & Rush, Edgar S.
Description: The main purposes of this study were to (a) obtain adequate test data to determine experimentally the vehicle cone index (VCI) for 50 passes for vehicles mounted with nonconventional tires and (b) use results of the field tests to develop a revised mobility index (MI) formula for self-propelled wheeled vehicles.

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

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).

Effects of Alterations to Low Gradient Reaches of Utah Streams

Effects of Alterations to Low Gradient Reaches of Utah Streams

Date: April 1980
Creator: Wydoski, Richard S.
Description: This report describes an investigation of the effects of stream channelization on fish and macro-invertebrates in low gradient reaches of Blacksmith Fork River and the Logan River in the floodplain of Cache Valley in northern Utah. Channelization adversely affected both fish and macro-invertebrate populations and biomass, with the severity of impact directly related to the amount and duration of disturbance of the physical habitat.
