Analysis and Comparison of Cement Selection in Ultra-High-Performance Concrete
(2022)Ultra-high-performance concrete (UHPC) is a relatively new material that is growing in popularity and usage over recent years. The greatly increased strength and durability of UHPC compared to conventional ACI concrete ... -
Analysis of composite concrete steel column using new steel section
(2021-05-07)Conventional concrete encased steel composite columns are typically constructed by embedded “W” steel section or other sections identified in the American Institute of Steel Construction “AISC”, positioned in the center ... -
Application of basalt fiber reinforced polymer rebar for prestressed concrete beams
(2022-08)All steel reinforced concrete infrastructure that is facing a chemical environment and corrosion will have their service life greatly reduced. With time it will lead to a premature and an inevitable failure of the steel ... -
Comparative Study of Surface Preparation And Bond Angle Combinations For Bridge Repair Using Ultra-High Performance Concrete Alternative
(2018-12)Ultra-high performance concrete (UHPC) is a type of concrete with advanced mechanical properties compared to normal strength concrete and that can be used for connections and repairs in bridges. Most UHPC used in the field ... -
DEVELOPMENT AND IMPLEMENTATION OF A MECHANISTIC AND EMPIRICAL DESIGN GUIDE (MEPDG) FOR RIGID PAVEMENTS — PHASE 2
(2014-10)The work investigates the impact of curing methods and their impact on subsequent curling in both the laboratory and the field in different drying environments. Results are also presented for a field instrumentation of a ... -

(2012-11)This reports completes a sensitivity analysis of the MEPDG based on Oklahoma pavements, provides a literature review of base material best practices, increases the Oklahoma weather data available for the MEPDG, investigates ... -
Evaluation of continuously reinforced concrete pavement
(1976-5)This report compares the performance of continuously reinforced concrete pavement with and with transverse steel. The construction of a CRCP project without transverse steel was done at the insistence of the Division FHWA ... -
Expected life of silane water repellent treatments on bridge decks phase 2 / M. Tyler Ley, Mehdi Khanzadeh Moradllo.
(Oklahoma City, OK : Oklahoma Department of Transportation, 2015., 2015-10)This report outlines the investigation of the service life of silane sealers on Oklahoma bridge decks as well as laboratory investigation of a silane sealer and a two part sealer that uses both silane and epoxy. The ... -
Fly ash concrete final report - a study of the reaction products using x-ray diffraction and SEM (82-01-2)
(1984-8)The setting and strength gaining process of P.C. concrete containing Class c high calcium fly ash were related to the reaction products which were identified using X-ray diffraction and scanning electron microscopy ( ... -
Measuring Air Void Characteristics of Oklahoma Air- Entrained Concrete using the Air Void Analyzer (AVA) / Analyzing AVA Sources of Error (FHWA-OK-08-03 2128)
(2009-1)The conventional method for measuring the size distribution of air voids in concrete (ASTM C457) requires a technician with highly-specialized training and can only be performed on hardened concrete. Waiting several days ... -
Performance of Fiber-Reinforced Eco-Friendly Concrete for Bridge Structures
(2016-08-12)Concrete is the leading building material in the world due to its readily available materials, strength, durability, and relatively low cost. With cities growing at a more rapid pace, the demand for concrete is increasing. ... -
PERFORMANCE OF ULTRA-THIN WHITETOPPING (UTW) IN OKLAHOMA
