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 ...
Field evaluation of drainable bases in Oklahoma (FHWA-OK-96-04) 2181
(1996-5)
The Oklahoma Department of Transportation (ODOT) Research and Development Division (R&D) installed field data acquisition systems in 1992 on five test pavement sections with a view to evaluate the performance of the drainable ...
Mix design using asphalt millings (FHWA-OK-00-04) 2148
(2000-8)
A field demonstration project was undertaken by the Research & Development Division, Oklahoma Department of Transportation (ODOT), to investigate the performance of an asphalt overlay constructed using recycled asphalt ...
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 ...
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 ...
FEABAS A user friendly software for prediction of bridge approach settlement (FHWA-OK-95-03) 2188
(1995-5)
Bridge approach settlement is a major problem in highway design as well as maintenance. It creates an unsafe and uncomfortable riding surface. This report presents the details of a software that was developed at the ...
Resilient moduli of raw and stabilized aggregate bases and evaluation of layer coefficients for AASHTO flexible pavement design volume I (FHWA-OK-98-05) 2199
