Interface Shear Strength in Lightweight Concrete Bridge Girders
… to develop composite action, adequate horizontal shear resistance must be provided at the interface. As lightweight concrete is increasingly being used in bridge designs, it is important to understand the horizontal shear behavior of lightweight concrete. The current AASHTO LRFD Specification …

Effects of Freezing Temperature on Interface Shear Strength of Landfill Geosynthetic Liner
… few decades. The present work emphasizes the shear strength of geocomposite clay liner (GCL) and geomembrane interface in landfills. Using direct shear tests, shear stress was measured as a function of normal load to determine the values of interface frictional angle and adhesion of the …

Laboratory Investigation of the Effects of Temperature and Moisture on Interface Shear Strength of Textured Geomembrane and Geosynthetic Clay Liner
… the effects of temperature and moisture on the shear strength of textured geomembrane (T-GM) and geosynthetic clay liner (GCL) interface. Several landfill slope failures involving geosynthetics have occurred within the past three decades. Interface shear strength of T-GM/GCL is well documented …

Comparative Assessment of Single & Double Interface Shear Strength Properties: A Case Study of a Landfill Project in the Western Cape Province, South Africa
… they have presented several new potential interfaces for shear failure, particularly on side-slopes and basins of conventional hole-in-ground type MSW landfills. In the laboratory, interface shear strength properties of either soil-geosynthetic or geosynthetic-geosynthetic are determined …

Comparison of shear strength properties of textured polyethylene geomembrane interfaces in landfill liner systems
The interface shear strength between geomembranes and geosynthetics is a critical factor governing the stability of slopes that incorporate geosynthetics. In order to better characterise the shear properties of geomembranes, a wide-range of shear strength friction measurements were conducted. This …

Enhancement of Shaft Capacity of Cast-in-Place Piles Using a Hook System
… the effect of passive inclusion on pile-soil interface shear strength behaviour, employing a modified direct shear test apparatus. The interface strength obtained for pile-soil specimens was found to significantly increase when passive inclusions were implemented. Residual friction angle for …

An experimental and analytic study of earth loads on rigid retaining walls
… lateral earth pressure theory and a vertical shear force theory. The compaction-induced lateral earth pressure theory was revised from a previous theory. The revisions improved the accuracy with which the theory models the hysteretic stress behavior of the backfill during compaction. The …

An Investigation into the Effects of Asperities on Geomembrane/Geotextile Interface Shear Characteristics
… system, which consists of multiple geosynthetics interfaces, the geomembrane/geotextile (GMB/GTX) interface is known to have relatively low shear strength. In an effort to mitigate sliding failure occurrence at the GMB/GTX interface, asperities have been incorporated into GMB manufacturing to …

Effect of grading and grain size on the friction characteristics of a sand/geotextile inteface
… It particularly focuses on the soil/geotextile interface behaviour. Geotextile reinforcements transfer a majority of the shear stress from the soil to the reinforcement and vice versa by friction. This interfacing ability manifested by the soil/geotextile frictional contact is very important in …

Development of a testing approach for tack coat application rate at pavement layer interfaces
… addition to difficulties in compaction, lack of interface bonding can lead to serious pavement deterioration including slippage cracking, de-bonding, and early fatigue cracking, all of which eventually reduce the pavement service life. Several experimental programs and numerical research have …

Evaluation of bonded concrete overlays on asphalt pavements
… Concrete samples were tested for compressive strength, split-tension strength, and coefficient of thermal expansion. Asphalt samples were characterized by their bulk specific gravity, Hamburg wheel testing device, and indirect tensile strength. The shear strength and bond failure mechanism …
