EVALUATION AND FIELD VERIFICATION OF STRENGTH AND STRUCTURAL IMPROVEMENT OF CHEMICALLY STABILIZED SUBGRADE SOIL (FHWA-OK-08-01 2195)
(20018-7)Often subgrade soils exhibit properties, particularly strength and/or volume change properties that limit their performance as a support element for pavements. Typical problems include shrink-swell, settlement, collapse, ... -
EVALUATION OF A FIXED ANTI-ICING TRACKING SYSTEM FOR SNOW REMOVAL AND ICE CONTROL (FHWA-OK 03(04) 2120)
(2003-4)The Fixed Anti-icing Tracking System is a stand alone, anti-icing liquid chemical spray system normally mounted on preselected highway bridges. These systems are designed to help prevent a strong bond of snow and/or ice ... -
Evaluation of a Pyrament bridge deck overlay (FHWA-OK-96-12)
(1996-12)The Oklahoma Department of Transportation (ODOT) has been using high density Portland cement (HDPC) overlays for more than twenty years to minimize spalls and delaminations in concrete. Since HDPC overlays were introduced, ... -
Evaluation of an experimental protective coating for bridge steel (88-03)
(1989-10)This report describes the application of an experimental metal sealer to bridge beams which are coated with lead-based paint. Regulations developed by the Environmental Protection Agency (EPA) , prohibit the introduction ... -
Evaluation of asphalt binders construction report (FHWA-OK-96-__) 2197
(1996-5)In August, 1995, The Oklahoma Department of Transportation- (ODOT) completed construction on ODOT Project Number NH-186(190). Briefly, this project consisted of milling and resurfacing a 10.9 km (6.8 mi) long section of ... -
Evaluation of bituminous mixes in pavement structures - final report
(1977-6)A summary of the research methodology, results, conclusions and recommendations of a five-year study of bituminous mixtures used in Oklahoma flexible highway pavements is presented in this terminal report. The research ... -
Evaluation of bituminous mixes in pavement structures interim report I - Analysis of mixes containing siliceous aggregates
(Jun-73)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 ... -
Evaluation of bituminous mixes in pavement structures interim report II - Characteristics of rutting on high quality bituminous highway pavements
(Dec-72)Rutting on high quality flexible pavement due to traffic action and is a functional as well as a structural type of failure. That is, it interferes with the quality of ride expected from such a surface and can be determintal ... -
Evaluation of bituminous mixes in pavement structures interim report III - A preliminary study of the use of the stiffness concept in minimizing
(Mar-76)Transverse cracking in flexible highway pavements is considered to be a serious and extensive problem by the asphalt paving technologist. There is a wide adreement that these cracks are caused primarily by the thermal ... -
Evaluation of bituminous mixes in pavement structures interim report IV - Development of surface deformations at statehighway 51 pavement test sites
(Jul-76)The development of rutting and other deformations in the pavement surface of two sites on a new section of State Highway 51 was monitored for a two year period. Transverse profile tracings, core samples, surface nuclear ... -
Evaluation of bituminous mixes in pavement structures interim report V - A study of transverse cracking in Oklahoma flexible highway pavements
(1977-1)Field and laboratory studies were made to investigate the nature and extent of transverse cracks on Oklahoma flexible pavements and to determine the possible causes of this form of distress. Only the influence and contribution ... -
Evaluation of Bonded Overlay and Dowel Bar Retrofit on I-40 (FHWA-OK-02-02 2404)
(2001-8)In October, 1998, The Oklahoma Department of Transportation (ODOT) constructed a 1,000 foot long, experimental section of fiber-reinforced PCC overlay over an existing jointed concrete roadway. The ODOT Research and ... -
Evaluation of bonded overlay and dowel bar retrofit on I-40 construction report (FHWA-OK-99-__) 2404
(1999-5)The Oklahoma Department of Transportation (OOOT) has completed a rehabilitation project on a 1,000 foot-long section of existing jointed PCC pavement. ThC section is located in the westbound traffic lanes of 1-40, in ... -
Evaluation of causes of excessive settlements of pavements behind bridge abutments and their remedies - phase I progress report no. 1 (84-12-2)
(1986-1)Bridge approach settlement problem is quite extensive in the U.S.A. This problem has been investigated since early 1960s, but no satisfactory solution has been achieved. A comprehensive literature search has been carried ... -
Evaluation of causes of excessive settlements of pavements behind bridge abutments and their remedies Phase II (FHWA-OK-89-06) 2148
