Ultrapave - final report (OK-97-10) 2293
(1997-11)Premature rutting is a common problem with asphalt concrete pavements, particularly when they are subjected to frequent heavy-axle loading. Producers of asphalt modifiers claim that polymers reduce rutting and other ... -
UNDERSTANDING A + B BIDDING PATTERNS AND POLICY IMPLICATIONS FOR ODOT PROJECT LETTINGS
(2014-10)A key challenge for Departments of Transportation around the country is to keep the cost of construction low while ensuring that projects will be completed in a timely manner. Those goals can often be conflicting. The ... -
Understanding A+B bidding patterns and policy implications for ODOT project lettings
(Oklahoma City, OK : Oklahoma Department of Transportation, 2014., 2014-10)We first surveyed all Transportation Agencies on their rules of implementation of A+B and incentive/disincentive designs. A complete survey of A+B and I/D letting practice is presented. Policy details such as application, ... -
Understanding A+B bidding patterns and policy implications for ODOT project lettings [Research highlighter]
(Oklahoma City, OK : Oklahoma Department of Transportation, 2016., 2016-12)Departments of Transportation (DOTs) are challenged with keeping the cost of construction low and ensuring timely project completion. A+B bidding is an innovative contracting design that allows contractors to propose an ... -
Use of an H20 meter for determination of concrete moisture content in the field
(1994-10)The ability to accurately determine concrete bridge deck moisture content could increase the probability of satisfactory performance of water repellent treatment materials through choosing favorable conditions for material ... -
Use of asphalt millings in subbase applications
(April, 199)Asphalt Concrete (AC) pavements, after a certain period of their service life, exhibit various types of deterioration and damage. To remedy these problems and to increase road safety, they are often overlaid with a new ... -
USE OF HIGH PERFORMANCE CONCRETE IN OKLAHOMA BRIDGE DECKS
(2006-7)An investigation was performed to develop four different high performance concrete (HPC) mixtures for the Oklahoma Department of Transportation’s (ODOT’s) 2004 Innovative Bridge Research and Construction (IBRC) project ... -
USE OF MSE TECHNOLOGY TO STABILIZE HIGHWAY EMBANKMENTS AND SLOPES IN OKLAHOMA (FHWA-OK-11-04 2214)
(2011-3)Departments of transportation across the U.S. are faced with the persistent problem of landslides and slope failures along roads and highways. Repairs and maintenance work associated with these failures cost these agencies ... -
THE USE OF RESISTIVITY TESTING FOR QUALITY CONTROL OF CONCRETE MIXTURES (FHWA-OK-20-03)
(2020-08)This study proposes a new quality control and compliance method for concrete mixture design using standard surface resistivity testing. This method helps in determining key mixture parameters such as fly ash content and ... -
Use of the dynamic cone penetrometer to verify and correlate with soil subgrade and aggregate base CBR values for the purposes of design of low volume traffic asphalt concete roadways
(March, 199)The use of the Dynamic Cone Penetrometer (DCP) has increased dramatically over the past several years. The primary reason for the increased use stems from improvements to the device and the development of correlation equations ... -
UTILIZING PAVEMENT FRICTION AND TEXTURE DATA FOR THE REDUCTION OF TRAFFIC CRASHES AND DELAYS (FHWA-OK-21-01)
(2021-03)This project presented an integral process to include skid performance of different preventive treatments and their safety benefits into the life cycle cost analysis (LCCA) of pavements. Extensive data sets from several ... -
VALIDATION AND REFINEMENT OF CHEMICAL STABILIZATION PROCEDURES FOR PAVEMENT SUBGRADE SOILS IN OKLAHOMA – VOLUME II (FHWA-OK-11-02(2))
(2011-10)For projects involving a chemically stabilized layer as a part of the structural design of the pavement, it is typical to conduct a mix design to assess the additive content needed to achieve a certain unconfined compressive ... -
