TEST METHODS FOR USE OF RECYCLED ASPHALT PAVEMENT IN ASPHALT MIXES (FHWA-OK-12-01 2223)
(2012-2)Usage of recycled asphalt pavement (RAP) in the construction of new pavements has increased in recent years due to the movement to conserve energy and raw materials, and reuse waste materials. To assess the effectiveness ... -
The construction of a pyrament bridge deck overlay (FHWA-OK-91-04)
(1991-5)The Oklahoma Department of Transportation (ODOT) has been using .High Density Portland Cement (HDPC) overlays on reconstruction of bridge decks smce 1977. At the time of introduction, the HDPC (Iov;a method) was considered ... -
The development of a portable steel reinforcing bar detection device for concrete bridge decks - second quarterly report
(1977-4)During the last quarter a variety of steel reinforcing bar (rebar) detection schemes were studied so that an optimum sensing device could be selected. It was found that magnetic techniques were superior to infrared, ... -
The Effects of Soil Suction on Shallow Slope Stability / Gerald A. Miller, Amy B. Cerato, Arash Hassanikhah, Maryam Varsei, Roy Doumet, Celine Bourasset, Rifat Bulut
(Oklahoma City, OK : Oklahoma Department of Transportation, 2015., 2015-12)Research work described in this report was undertaken to improve understanding of desiccation cracking and shallow slope failures in clayey slopes subjected to seasonal variations in weather. Research involved field and ... -
The evaluation of non-woven fabrics - petromat and mirafi (FHWA-OK-82-6) 2278
(1982-5)The objective of this report is to study non-woven Thermoplastic fiber fabrics and their effects in eliminating and diminishing reflective cracking in asphalt concrete overlays. Two fabrics, namely Petromat and Mirafi 140, ... -
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 ... -
