Sampling Disturbance Effects in Normally Consolidated Clays
Publisher: American Society of Civil Engineers
Abstract: The effects of sampling disturbance are investigated by performing single element triaxial tests in which specimens of normally consolidated resedimented Boston blue clay are disturbed according to the “perfect sampling ...
Fractional Viscoelastic Modeling of Antirutting Response of Bituminous Binders
Publisher: American Society of Civil Engineers
Abstract: A three-parameter fractional model, composed by a springpot in series with a dapshpot, was employed to describe the rheological behaviour of a set of polymer-modified bituminous binders obtained by combining a single-base ...
One-Dimensional Compression Behavior of a Soil with High Organic Matter Content
Publisher: American Society of Civil Engineers
Abstract: This paper addresses the one-dimensional compression behavior of a highly organic sapric soil in both its natural intact and reconstituted states, based on the results of constant rate of strain and incremental loading ...
Factors Affecting the Initial Stiffness of Cohesive Soils
Publisher: American Society of Civil Engineers
Abstract: The paper presents the results of an extensive laboratory program conducted to establish the factors affecting the initial stiffness (Young’s modulus) of cohesive soils in undrained triaxial compression. The testing program, ...
Laboratory Simulation of Field Sampling: Comparison With Ideal Sampling and Field Data
Publisher: American Society of Civil Engineers
Abstract: Tube sampling disturbance effects are investigated in this paper based on the results of constant rate of strain consolidation tests and unconsolidated undrained triaxial compression tests conducted on resedimented Boston ...
Small-Strain Nonlinearity of Normally Consolidated Clay
Publisher: American Society of Civil Engineers
Abstract: This paper addresses the small-strain undrained shear behavior of clays based on an extensive testing program conducted on normally consolidated resedimented Boston blue clay (RBBC). The uniformity and reproducibility in ...
Fractional Viscoelastic Modeling of Antirutting Response of Bituminous Binders
Publisher: American Society of Civil Engineers
Abstract: A three-parameter fractional model, composed by a springpot in series with a dapshpot, was employed to describe the rheological behaviour of a set of polymer-modified bituminous binders obtained by combining a single-base ...
Liquefaction Mitigation Using Bentonite Suspensions
Publisher: American Society of Civil Engineers
Abstract: Ottawa sand specimens premixed with 0, 3, and 5% bentonite by dry mass of sand were tested under undrained static and cyclic loading to investigate the effects of bentonite on the static and cyclic shear strength of the ...
Determination of Crumb Rubber Content of Asphalt Rubber Binders
Publisher: American Society of Civil Engineers
Abstract: The study focused on two new laboratory procedures developed for the determination of crumb rubber content of asphalt rubber binders. The first methodology was on the basis of the comparative analysis of cobalt and antimony ...
