(2020-11-17)Design and material selection of bituminous mixtures (asphalt concrete) have a decisive role in mixture and pavement performance. Traditionally, the design of the mixtures has focused on the volumetric fractions of components. ...
-
(2012-10-08)Rutting is one of the major distresses in asphalt pavements and it increases road roughness and traps water, which leads to wet-weather accidents due to the loss of tire-pavement friction and hydroplaning. The fundamental ...

Approximate solution for a rolling contact problem over a relatively general viscoelastic half-space (Texas A&M University. Libraries, 1977)An approximate method is developed to predict the coefficient of friction and normal load for the problem of a rigid circular cylinder moving across a relatively general viscoelastic half-space with constant velocity. The ...

(2015-05-01)Oxidative aging is known to be one of the main contributors to reducing the service life of asphalt pavements. Asphalt concrete becomes stiffer and more brittle when it reacts with oxygen. The aged asphalt pavement is more ...
-
(Texas A&M University. Libraries, 1976)Viscous and elastic rheological properties of three very dilute polymer solutions (100 to 500 parts per million) of a polyacrylamide in distilled water have been determined. By using the Weissenberg Rheogoniometer, both ...
-
(Texas A&M University. Libraries, 1988)It has been proved by many researchers that existing fatigue failure criteria based on constant amplitude loading tests underpredict the fatigue life of asphalt concrete pavements. Unrealistic loading conditions in laboratory ...
-
(2012-07-16)This thesis employs a finite element (FE) method for numerically simulating the mechanical response of constituents in a fiber-reinforced polymer (FRP) composite to indentation. Indentation refers to a procedure that ...
-
(2009-05-15)Nature encourages diversity in life forms (morphologies). The study of morphogenesis deals with understanding those processes that arise during the embryonic development of an organism. These processes control the organized ...
-
(2013-04-30)The mechanical behavior of asphalt binders is nonlinear. The binders exhibit shear thinning/thickening behavior in steady shear tests and non-proportational behavior in other standard viscoelastic tests such as creep-recovery ...
-
(2010-01-14)Fiber Metal Laminates (FML) are hybrid composites with alternate layers of orthotropic fiber reinforced polymers (FRP) and isotropic metal alloys. FML can exhibit a nonlinear thermo-viscoelastic behavior under the influence ...
-
(2010-07-14)The present research seeks to study the decrease in diffusivity rate as relative humidity (RH) decreases and modeling drying shrinkage of hardened cement paste as a poroviscoelastic respose. Thin cement paste strips of 0.4 ...
-
(2019-11-30)In this dissertation, the concept of seismically resilient bridge columns with polyurethane (PU)-enhanced damage-resistant (DR) joints and replaceable energy dissipating (ED) links is proposed. The proposed system introduces ...
-
(2012-07-16)We consider the application of high-order spectral/hp finite element technology to the numerical solution of boundary-value problems arising in the fields of fluid and solid mechanics. For many problems in these areas, ...
-
(2012-10-19)Time- and rate-dependent materials such as polymers, bituminous materials, and soft materials clearly display all four fundamental responses (i.e. viscoelasticity, viscoplasticity, viscodamage, and healing) where contribution ...
-
(Texas A&M University. Libraries, 1986)In recent years, there has been an increase in the use of flexible plastic pipes as buried conduits even though much of the soil-pipe behavior has not been fully understood. Present design approaches either involve the use ...
-
(Texas A&M University. Libraries, 1981)To obtain deformation properties of submarine sediment a device which imposes a simple shear state of strain was designed. A thorough literature review was conducted to evaluate the merits of previously developed simple ...
-
(Texas A&M University. Libraries, 1993)Almost all engineering materials exhibit creep and relaxation behavior. The observed magnitude depends on temperature, stress level and loading duration. Some polymers are further influenced by moisture contents as well. ...
