(1968-4)All data collected at the first 30 field test sites during the period June 1966-August 1967 are presented. Procedures for data collection, reduction, and display are described and discussed but no evaluation or correlation ... -
Subgrade moisture variations interim report VI Evaluation of collected data 1966-1967
(1968-5)Data collected at field test sites 1-30 during the period June, 1966 - August, 1967 are evaluated, relating measured subgrade moisture changes to soil, climate, and pavement conditions. Relevant data were coded on IBM cards ... -
Subgrade moisture variations interim report VII Subgrade temperature measurement
(1969-6)Measured moisture conditions at several existing field research sites could not be related to precipitation, and were thought to be temperature-dependent. Accordingly, subsurface thermistor probes were installed at six ... -
Subgrade moisture variations interim report VIII Evaluation of collected data 1966-1969
(1970-6)A prime objective of this research is to related measured moisture changes to soil, climate, and pavement behavior in Oklahoma. Previous interim reports have described operational methodology, procedures for collection and ... -
Technical stuides on asphalt report no. 1 - spectral analyses of hot recycling agents (83-02-2)
(1983-5)This report contains standardized baseline dat a for a series of Hot Recycling Agents and AC-3 asphalt. The hot recycling agents are identified by their RA number (RA-6, RA-25, RA-100 and RA-275) where the RA number is ... -
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 ... -
Terminal end joints in continuously reinforced concrete pavement interim report (FHWA-OK-92-__)
(1992-10)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 ... -
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, ... -
