Laboratory Characterization of Foamed WMA Containing RAP
Rahman, Mohammad (2019-08-01)For more than two decades, the asphalt paving industry has been using Reclaimed Asphalt Pavement (RAP) and various types of Warm Mix Asphalt (WMA) technologies in the production of asphalt mixes to reduce impact on the ... -
LABORATORY DEVELOPMENT AND MOLECULAR-SCALE SIMULATION OF SENSOR-ENABLED GEOGRIDS
Yazdani, Hessam (2015-12-18)Structural health monitoring (SHM) and performance assessment are increasingly integrated to modern civil engineering projects in order to prevent and mitigate their catastrophic premature failures. Significant advancements ... -
Lateral deformation of bridge embankments supported on soft soils
Bounds, Tommy (2020-12)Excessive bridge embankment deformation, namely in the lateral direction, continues to damage bridges leading to costly repairs or early replacement. The lateral deformation of bridge embankments is often overlooked in ... -
Mix design using asphalt millings (FHWA-OK-00-04) 2148
Issa, Rita; Zaman, Musharraf; Miller, Gerald (2000-8)A field demonstration project was undertaken by the Research & Development Division, Oklahoma Department of Transportation (ODOT), to investigate the performance of an asphalt overlay constructed using recycled asphalt ... -
Moisture-Induced Damage Characterization of Asphalt Mixes: A Chemical, Thermodynamic and Mechanistic Approach
Ali, Syed Ashik (2021-05)Moisture-induced damage is one of the major distresses which leads to the deterioration of mechanical properties of asphalt mixes and failure of asphalt pavements. Evaluation of the moisture-induced damage potential is a ... -
Overturning Forces at Bridge Abutments and the Interaction of Horizontal Forces from Adjacent Roadways (FHWA-OK-17-03)
Muraleetharan, K.K.; Miller, Gerald; Floyd, Royce; Zhang, Bo; Taghavi, Amirata; Bounds, Tommy; Bright, Zachary (Jan-18)ODOT is experiencing a number of problems related to the interactions between bridge abutments and adjacent roadways. These problems include expansion joints closing, roller support bearings tilting, and beams pushing ... -
Quantifying the Impact of Experimental Factors on the Measurement of Dynamic Capillary Effects in Unsaturated Porous Media
Hou, Lili (2014-12-12)Multiphase flow is an important phenomenon in many natural and engineering systems; for example, oil recovery and water movement in the unsaturated zone are two common multiphase flow systems. The capillary pressure-saturation ... -
RHEOLOGICAL PROPERTIES OF POLYMER AND RAP MODIFIED ASPHALT BINDERS USING MULTIPLE STRESS CREEP AND RECOVERY METHOD
Ali, Syed Ashik (2016-12)In recent years, asphalt modifications have become increasingly popular in asphalt pavement construction. Also, in view of technical, environmental and economic benefits, the pavement industry is in favor of using high ... -
Seismic Analysis of Single and Grouped Helical Piles in Dense Sand with Soil-Structure Interaction
