DEVELOPMENT OF FLEXIBLE PAVEMENT DATABASE FOR LOCAL CALIBRATION OF MEPDG (FHWA-OK-11-06(1) 2209)
(2011-6)
The new mechanistic-empirical pavement design guide (MEPDG), based on the National Cooperative Highway Research Program (NCHRP) study 1-37A, replaces the widely used but more empirical 1993 AASHTO Guide for Design of ...
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 ...
Field Performance Monitoring and Modeling of Instrumented Pavement on I-35 in McClain County
(Oklahoma City, OK : Oklahoma Department of Transportation, 2014., 2015-04)
Phase 1 of this project was conducted to better understand the cause of pavement failure under actual traffic loading and environmental conditions. A 1,000-ft. long experimental pavement section was constructed on I-35 in ...
RECOMMENDED FATIGUE TEST FOR OKLAHOMA DEPARTMENT OF TRANSPORTATION (FHWA-OK-16-05 2243)
(2017-10)
The primary objective of this study was to evaluate different fatigue test methods and to recommend the most suitable one to Oklahoma Department of Transportation (ODOT). In order to achieve this objective, six commonly ...
Creep Compliance and Percent Recovery of Oklahoma Certified Binders Using the Multiple Stress Creep Recovery (MSCR) Method
(Oklahoma City, OK : Oklahoma Department of Transportation, 2015., 2015-04)
A laboratory study was conducted to develop guidelines for the Multiple Stress Creep Recovery (MSCR) test method for local conditions prevailing in Oklahoma. The study consisted of commonly used binders in Oklahoma, namely ...
Tube Suction Test for Evaluating Durability of Cementitiously Stabilized Soils (FHWA-OK-11-05 2215)
(2011-6)
In a comprehensive laboratory study, different tests namely, unconfined compressive strength (UCS) at the end of freeze-thaw/wet-dry (F-T/W-D) cycles, resilient modulus (Mr) at the end of F-T/W-D cycles, vacuum saturation, ...
Fatigue Performance of Asphalt Pavements Containing RAS and RAP
(Oklahoma City, OK : Oklahoma Department of Transportation, 2015., 2015-01)
Rising oil and gas prices spurs development of methods and technologies for reducing fuel consumption and increased use of recycled materials. With increased environmental awareness, using reclaimed asphalt pavement (RAP) ...
DEVELOP DRAFT CHIP SEAL COVER AGGREGATE SPECIFICATION BASED ON AGGREGATE IMAGING SYSTEM (AIMS) ANGULARITY, SHAPE, AND TEXTURE TEST RESULTS
(2014-1)
The objective of the study is to improve Oklahoma Department of Transportation (ODOT) chip seal design and performance through introducing new criteria for the selection of cover aggregate and binder. The study evaluates ...
DEVELOPMENT OF ODOT GUIDELINES FOR THE USE OF GEOGRIDS IN AGGREGATE BASES (FHWA-OK-12-04 2220)
(2012-3)
A primary objective of the current study was to help ODOT expand its selection of approved geogrid products for base reinforcement applications by producing measured ata on selected geogrids and a dense-graded base aggregate ...
