Characterization of aquatic use attainment in Oklahoma /
(1984)
This research describes the application of an aquatic use assessment methodology referred to as use attainability analysis (UAA). The EPA has issued guidelines governing the process of Water Quality Standards' review and ...
A LABORATORY INVESTIGATION AND MODELING OF DYNAMIC MODULUS OF ASPHALT MIXES FOR PAVEMENT APPLICATIONS
(2011)
Traditionally, stiffness of hot mix asphalt (HMA) has been used as a measure of the pavement's ability to carry vehicular traffic loads without undergoing excessive deformation. Early deterioration of pavements due to ...
Evaluation of toxic metals in natural fish populations in Oklahoma.
(1981)
The level of toxic metals was low in the water samples but were much higher in the sediment samples. There were no significant correlations beween the levels of toxic metals in the water to the levels in the sediment.
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 ...
Characterization of Rutting in Asphalt Pavements using Laboratory Testing
(2019)
In asphalt pavements, rutting is one of the main concerns at high in-service temperature, which can occur either through plastic flow or shear in structural layers. Rutting depends on several factors, such as asphalt binder ...
A mathematical model and integrated simulation for urban flood and land use analysis /
(1983)
A mathematical model for estimating potential urban flood damages was developed. Model parameters and variables were determined and verified by statistical analyses. HEC-1 and HEC-2 programs were used to simulate the ...
SEISMIC AND QUASI-STATIC LATERAL LOAD BEHAVIOR OF PILE GROUPS IN IMPROVED SOFT CLAY: CENTRIFUGE AND NUMERICAL MODELING
(2015-12-18)
In the design of pile foundations subjected to lateral loading, one of the objectives is to restrict the lateral displacements. Improving the soil surrounding the pile foundation is an innovative and cost-efficient solution ...
DEVELOPMENT OF A PROTOTYPE IN-SITU FATIGUE SENSOR FOR STRUCTURAL HEALTH MONITORING OF HIGHWAY BRIDGES
(2010)
Fatigue damage to bridges has been identified as a threat to bridge safety. Fatigue cracks usually occur at stresses lower than the anticipated design stress levels. Unlike yielding or corrosion, fatigue cracks are seldom ...
