EVALUATION OF FIBER REINFORCED POLYMER (FRP) STRENGTHENING FOR DETERIORATED BRIDGE BENT CAPS
(2018-08-13)Deterioration of aging highway bridges has been a serious concern in the U. S. A. Almost 39% percent of all bridges in the country have passed their 50-year design life, and approximately 9% of these bridges are structurally ... -
EVALUATION OF FIRE-AFFECTED CONCRETE STRUCTURES BY NON-DESTRUCTIVE TESTING METHODS
(2019-12-06)Fire hazard on concrete structures has been a significant concern around the world. After a fire hazard, the crucial part is the evaluation of the fire-affected concrete for strengthening or demolition. For evaluation of ... -
Evaluation of Geotechnical Parameters of Soil Using Electrical Resistivity Imaging
(2021-12-20)Electric resistivity imaging (ERI) is an effective non-destructive and rapid measuring way of obtaining continuous soil subsurface resistivity profiles. An ERI technique can be used to identify moisture variations and soil ... -
Evaluation Of Lightweight Geofoam For Mitigating Bridge Approach Slab Settlements
(Civil & Environmental Engineering, 2014-12)The bump at the end of a bridge infrastructure is one of the frequent problems found in Texas and other states. Transportation agencies spend millions of dollars annually to repair the bump problem. The major cause of the ... -
EVALUATION OF MODEL UNCERTAINTIES IN LRFD CALIBRATION PROCESS OF DRILLED SHAFT AXIAL DESIGN
(2019-08-12)The Federal Highway Administration (FHWA) released a policy in 2000 that required all new federally funded bridges to be designed using the AASHTO LRFD specifications by October 2007. The transition from ASD to LRFD posed ... -
Evaluation Of Physico-mechanical Properties Of Clayey Soils Using Electrical Resistivity Imaging Technique
(Civil & Environmental Engineering, 2014-07-14)Resistivity imaging (RI) is a promising approach to obtaining continuous profile of soil subsurface. This method offers simple technique to identify moisture variation and heterogeneity of the investigated area. However, ... -
Evaluation of Plant Root on the Performance of Evapotranspiration (ET) Cover System
(2017-12-07)The performance of an evapotranspiration (ET) cover for a landfill exceeds that of a conventional landfill final cover. Its low percolation and high evapotranspiration rely on the properties of unsaturated soils, the energy ... -
EVALUATION OF RECYCLED PLASTIC PINS AS SHEAR KEYS IN MSE WALL BASE
(2021-05-06)Mechanically Stabilized Earth (MSE) walls have been widely used as retaining structures due to their flexible nature, a better tolerance against differential settlement, and many other factors. However, external stability ... -
EVALUATION OF STRUCTURAL CAPACITY OF EPOXY-COATED CONCRETE PIPES AND ITS INTERACTION WITH SOIL
(2016-08-18)Rehabilitation of concrete structures by using synthetic resins such as epoxy is increasing worldwide. Understanding the structural behavior of the resultant composite structure and the interaction between the coating and ... -
Evaluation of Surface Asphalt Mixes containing Recycled Asphalt Materials in North-East Texas using Accelerated Pavement Testing
(2021-12-20)Reclaimed asphalt pavement (RAP) and Reclaimed Asphalt Shingles (RAS) has proved to be an effective alternative to virgin materials in HMA production. Despite that recycling asphalt creates a cycle that optimizes the use ... -
Evaluation Of Surface Transportation Funding Alternatives Using Criteria System Established Through A Delphi Survey Of Texas Transportation Experts
(Civil & Environmental Engineering, 2014-03-12)For more than a decade, transportation officials have been concerned that, at current levels, the fuel tax, the primary funding source of surface transportation in the United States, would not provide enough revenue to ... -
Evaluation of the Structural Performance of Bridge MSE Retaining Walls
(2019-12-06)Mechanically Stabilized Earth (MSE) walls have been used extensively since the first MSE wall constructed in California in the early 70’s. MSE walls proved that they are reliable, cost-effective, aesthetically pleasing, ... -
