Energy Harvesting on Highway Bridges (FHWA-OK-11-01 2224)
(2011-1)
A concept for harvesting energy from the traffic-induced loadings on a highway bridge using piezoelectric
materials to generate electricity was explored through the prototype stage. A total of sixteen lead-zirconate
titanate ...
Expected life of Silane water repellant treatments on bridge decks (FHWA-OK-12-08)
(2012-12)
This report covers techniques used to evaluate the presence of silane coatings on bridge decks in the lab and in the field. After these techniques are established they are then used to determine the effective service life ...
IMPLEMENTATION OF PESTICIDE APPLICATOR CERTIFICATION SCHOOLS AND CONTINUING EDUCATION WORKSHOPS (FHWA-OK-16-10 2156)
(2016-12)
The Oklahoma Department of Transportation’s (ODOT) herbicide applicator training program consists of initial pesticide applicator training schools, independent certification testing, sprayer calibration workshops and ongoing ...
EVALUATION OF THE ENHANCED INTEGRATED CLIMATIC MODEL FOR SPECIFICATION OF SUBGRADE SOILS IN OKLAHOMA
(2014-1)
The main objective of this study was to collect and evaluate climatic and soil data pertaining to Oklahoma for the climatic model (EICM) in the mechanistic-empirical design guide for pavements. The EICM climatic input files ...
Field performance monitoring and modeling of instrumented pavement on I-35 in McClain county - phase I
(2013-6)
Flexible pavements comprise about 93 percent of paved roads in the United States. Although flexible pavements are widely used for reasons such as cost, constructability and consistent performance, they are often subject ...
SELECTION OF LONG LASTING REHABILITATION TREATMENT USING LIFE CYCLE COST ANALYSIS AND PRESENT SERVICEABILITY RATING
(2015-10)
A wide range of variables influence the selection strategy for rehabilitation and maintenance of pavements. The focus of this study is to conduct a project-level evaluation of high traffic volume asphalt-surfaced pavements ...
EFFICACY OF ROAD BOND AND CONDOR AS SOIL STABILIZERS (FHWA-OK-13-06 2242)
(2013-8)
The Oklahoma Department of Transportation (ODOT) uses lime-based stabilizers including quick lime, hydrated lime, Class C fly ash (CFA) and cement kiln dust (CKD) to increase bearing capacity of fine-grained subgrade soils ...
PORTABLE WEIGH-IN-MOTION FOR PAVEMENT DESIGN - PHASES 1 AND 2
(2014-9)
Keeping Oklahoma's roadways, highways, and bridges in good condition is necessary to our state’s safety and to avoid expenditures in billions of dollars each year for road repairs and replacement. According to a study done ...
