Terminal end joints in continuously reinforced concrete pavement (FHWA-OK-91-01)
(1991-3)During the past 20 years, the Oklahoma Department of Transportation (ODOT) has constructed over 450 lane miles of Continuously Reinforced Concrete Pavement (CRCP) on its interstate and U.S. highway system. Throughout that ... -
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 ... -
Evaluation of retroreflective sheetings for use on traffic control devices at construction work sites (FHWA-OK-91-06) 2177
(1991-6)The overall objective of this project was to evaluate the relative adequacy of the engineering grade, super-engineering grade, and high-intensity grade sheetings when used on traffic control devices at construction work ... -
Freeze-thaw durability of concrete made with marginal aggregate (FHWA-OK-91-04) 2137
(1991-6)Much of the crushed limestone aggregate produced in the Oklahoma region is susceptible to freeze-thaw action and can result in popouts and D-cracking in concrete. Four series of tests involving over 120 batches of concrete ... -
Evaluation of coatings applied over corroded structural steel surfaces (FHWA-OK-91-05) 2722
(1991-6)Results are presented for accelerated corrosion tests of five coating systems evaluated for use over corroded structural steel surfaces. This was the second series of such tests in a testing program initiated in 1988. The ... -
Assessment of resilient modulus testing methods and their application to design of pavements (FHWA-OK-91-08)
(1991-6)Resilient modulus (RM) is an important property of subgrade soils that accounts for repetitive loads due to vehicular traffic. Since AASHTO recommended its use in pavement design in 1986, various transportation agencies ... -
Expert systems applications for ODOT (FHWA-OK-91-09)
(1991-7)Expert systems are "intelligent" computer programs which have the capabilities of reasoning, learning, and simulating human sensory capabilities. Solutions to many problems in transportation engineering which are not well ... -
Depressed transverse cracks in asphalt pavements in Oklahoma (FHWA-OK-92-1) 2166
(1991-7)Transverse cracking of asphalt pavements is a costly pavement distress occurring in states that experience cold/freezing temperatures during the winter months. The cracks are caused by low temperature-induced tensile ... -
