Study of Clay Shale Slopes Along the Panama Canal, Report 3: Engineering Analyses of Slides and Strength Properties of Clay Shales Along the Gaillard Cut

"The results of the engineering studies and analyses which provide guidance on shear strength parameters applicable to the stability evaluation of existing slopes along the Gaillard Cut, the effects of future modifications, and evaluation of newly excavated slopes in clay shales are summarized in this report" (abstract). This report includes the appendices containing enginering data, characteristics of materials, analysis of past slides, active slopes, and hydrographic survey data.

Nondestructive Vibratory Testing of Airport Pavements: Volume 1, Experimental Test Results and Development of Evaluation Methodology and Procedure (open access)

Nondestructive Vibratory Testing of Airport Pavements: Volume 1, Experimental Test Results and Development of Evaluation Methodology and Procedure

From abstract: Conventional direct sampling methods of airport pavement evaluation interfere with aircraft operations; therefore, an evaluation procedure based on nondestructive vibratory testing was developed.

Physical Hydraulic Models: Assessment of Predictive Capabilities; Report 1: Hydrodynamics of the Delaware River Estuary Model (open access)

Physical Hydraulic Models: Assessment of Predictive Capabilities; Report 1: Hydrodynamics of the Delaware River Estuary Model

Partial abstract: The purpose of this study is to define the reliability with which results of tests conducted in a physical model of the Delaware River Estuary can be used to predict the effects of modifications to the estuary. The Delaware River model at the Waterways Experiment Station was used to conduct tests to predict the effects of the navigation channel enlargement between Philadelphia and Trenton, and the results of the tests are compared with subsequent prototype data to determine the accuracy of the model predictions.

Investigation of Nonmetallic Waterstops Report 9: Final Report of Effect of Exposure (open access)

Investigation of Nonmetallic Waterstops Report 9: Final Report of Effect of Exposure

Final report describing the results of experiments to test samples of rubber, synthetic rubber, and polyvinylchloride (PVC) to determine their suitability for use in nonmetallic waterstops. During the tests, each of the samples was exposed to various conditions and environments before evaluation. This report discusses longer exposures of materials, to follow the previous report in the series discussing an evaluation of the same tests.
