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 ...
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 ...
Analysis of Aggregates and Binders Used for the ODOT Chip Seal Program (FHWA-OK-10-03 2221)
(2010-11)
This project compared the results of laboratory characterization of chip seal aggregate samples for Oklahoma DOT Divisions 1,2,3,5 and 6 with performance data from the Pavement Management System (PMS) database. Binder ...
DRYING SHRINKAGE PROBLEMS IN HIGH PI SUBGRADE SOILS
(2014-1)
The main objective of this study was to investigate the longitudinal cracking in pavements due to drying shrinkage of high PI subgrade soils. The study involved laboartory soil testing and modeling. The shrinkage cracks ...
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) ...
