Resilient Moduli of Treated Clays from Repeated Load Triaxial Test
Transportation Research Record: Journal of the Transportation Research Board, 2003Three chemical stabilization methods—sulfate resistant cement (Type V), low-calcium fly-ash (Class F) mixed with sulfate resistant cement (Type V), and ground granulated blast furnace slag—were used in a series of repeated load triaxial tests on clayey soil to assess the effectiveness of these three stabilizers in enhancing ...

Evaluation of Geogrid Benefits Using Monotonic and Repeated Load Triaxial Tests
Analysis of Asphalt Pavement Materials and Systems, 2007A series of monotonic and repeated load resilient modulus triaxial tests were conducted on unreinforced and geogrid reinforced crushed limestone samples to evaluate the effects of the stiffness, location, and number of geogrid layer/s on the strength properties and stress strain response parameters of those samples.

Geotechnical Testing Journal, 2003
Abstract Drained repeated load triaxial compression tests were conducted to investigate the resilient and permanent stress-strain behavior of two granular materials reinforced by a geogrid. In order to obtain more accurate measurement of recoverable deformation, an on-sample measuring method was utilized.

Repeated Load Triaxial Testing of Recycled Concrete Aggregate for Pavement Base Construction
Geotechnical and Geological Engineering, 2012This paper presents the results and analysis of Repeated Load Triaxial Testing (RLTT) conducted on three basecourse products; two crushed concrete, or Recycled Concrete Aggregate (RCA) materials, and a local Virgin Aggregate (VA). The objective of this testing program was to study the impact of applied stress states on resilient modulus and permanent ...

A Repeated Loading Triaxial Test Study on Resilient Modulus of Graded Crushed Stone
Advanced Materials Research, 2012To investigate the effect of confining stress, deviation stress, moisture content and gradation type on resilient modulus of graded crushed stones, three types of graded crushed stone with three moisture content levels(optimum moisture content and ±2% of the optimum moisture content, respectively ) were used, and repeated loading triaxial (RLT) tests ...

Plastic Deformation Potentials of Sandy Clay from Repeated Load Triaxial Test
Geotechnical Engineering for Transportation Projects, 2004Design and analysis of flexible pavement systems depend on soil layer characterization, traffic loads and number of passes. Currently, AASHTO uses resilient characteristics of subsoils to characterize and determine the structural support of each layer and then designs the layer thickness. Resilient properties are used in the characterization since they

A technique for measuring radial deformation during repeated load triaxial testing
Canadian Geotechnical Journal, 1978A system of non-contacting displacement transducers has been used to record radial deformation in repeated load triaxial tests. Operating principle, system capabilities, and installation technique are discussed. Results of tests on clay and silt subgrade materials are presented and Poisson's ratio is calculated directly from test data.

Characterization of Unbound Granular Materials Using Repeated Load CBR and Triaxial Testing
Paving Materials and Pavement Analysis, 2010Because repeated load triaxial testing is cumbersome and not readily available, especially in developing countries, characterization of unbound granular road base and subbase materials is still done using empirical methods such as California Bearing Ratio (CBR) testing.

Transportation Research Record: Journal of the Transportation Research Board, 1998
Determination of both axial and radial specimen strains in a repeated load triaxial test is essential for properly characterizing the directional dependency of resilient granular material behavior. Radial deformation measurement is not yet included in the standard AASHTO test procedure.
