Laboratory and model prediction of rutting in asphalt concrete.
(2003)
Rutting is one of the major distresses of flexible pavement. It is defined as the formation of longitudinal depressions under the wheel paths caused by the progressive movement of materials under traffic loading in the ...
Static and dynamic behavior of multiphase porous media: Governing equations and finite element implementation.
(2001)
The mechanical behavior of porous media such as geomaterials is largely governed by the interactions of the solid skeleton (or grains) with the fluids existing in the pores. These interactions occur through the interfaces ...
Effect of additives on surface free energy characteristics of aggregates and binders in hot mix asphalt.
(2007)
U.S. spends approximately $20 billion/year on asphalt pavements with disproportionately high maintenance costs of $9.3 billion/year. Better performance of asphalt pavements is crucial to reducing these maintenance costs. ...
The poromechanics of naturally fractured rock formations: A finite element approach.
(2003)
The mathematical models have been cast into finite element form and verified against analytical solutions for one-dimensional consolidation and an inclined wellbore in a fully saturated single-porosity formation subjected ...
FORMATION, CHARACTERIZATION AND APPLICATION OF TRIGLYCERIDE MICROEMULSIONS USING EXTENDED SURFACTANTS
(2009)
Triglycerides are among the most challenging oils to microemulsify due to their unique structure of a bulky polar ester head and three long hydrocarbon chains. Among the published work on triglyceride microemulsions, the ...
High performance concrete in Oklahoma designed for precast/prestressed bridge beams.
(2003)
It was learned that all cements and aggregates in the test group appear suitable for producing HPC, but some cements and aggregates are better in precast/prestressed concrete applications. Cement selection is crucial to ...
Testing and modeling of unsaturated interfaces.
(2005)
A conventional fully automated direct shear test device was modified to achieve the objectives of this study. The newly developed device, called the Unsaturated Interface Direct Shear Apparatus (UIDSA), was equipped for ...
Characterizing components of uncertainty in hydrologic modeling using an ensemble approach.
(2003)
In hydrologic modeling, uncertainties are known to reside in model inputs, i.e., rainfall estimates, model parameters, observations of streamflow, and in some cases in the model structure itself. Estimation of the total ...
Pressuremeter and cone penetrometer testing in a calibration chamber with unsaturated Minco Silt.
(2005)
The focus of this study is to investigate the influence of matric suction (&psgr; ) on PMT and CPT results by conducting miniature pressuremeter (MPMT) and miniature cone penetrometer (MCPT) testing in a calibration chamber ...
