The impact of highway construction on a fresh water stream - a demonstration project
(1988-12)Oklahoma Department of Transportation (ODOT) commenced a demonstration study in 1976 to determine the impact of highway construction on a fresh water stream. A creek near a highway construction site along US-69 at Limestone ... -
The Need for Air Entrainment in High Performance Concrete (FHWA-OK-03-05 2145)
(2003-7)The use of high performance concrete (HPC) in exterior structures has increased in recent years. Its increased strength and durability make HPC very appealing to the prestressed concrete industry, particularly in bridge ... -
The Study of Vehicle Classification Equipment with Solutions to Improve Accuracy in Oklahoma
(Oklahoma City, OK : Oklahoma Department of Transportation, 2014., 2014-12)The accuracy of vehicle counting and classification data is vital for appropriate future highway and road design, including determining pavement characteristics, eliminating traffic jams, and improving safety. Organizations ... -
The use of heat pipes to prevent ice formation on highway bridge decks
(1973)Sufficient heat can be transported from the surrounding ground to a bridge deck by heat pipes to both reduce the number of freeze-thaw cycles and to reduce the time during which the surface is below freezing. In a computer ... -
Thin asphalt overlays in Division VI (OK-96-11) 2285
(1996-10)Field Division VI has typically applied "chip seals'' to distressed low traffic roadways. Chip seals, however, have little effect on problems such as cracking, corrugating, and rutting. One or more of these problems existed ... -
Trinity Cable Safety System (FHWA-OK 07(01) 2130)
(2007-1)CableSafety System (CASSª).is being tested'by the Oklahoma Department of Transportation (ODOT) along I- 35 in McClain County. CASSª will be compare with two other system approve by ODOT. Using C-shaped posts and tensioned ... -
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, ... -

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 ... -
