Major investment analysis for multimodal projects in urban corridors - phase I report
(1994-12)
Recent legislative and regulatory actions require major investment analyses of transportation projects prior to construction. These analyses must respect the intermodal consequences of proposed actions. The most commonly ...
Fatigue assessment of bridge members based on in-service stresses - final report (FHWA-OK-97-06) 2196
(1997-7)
This report summarizes research activities which are described in detail in interim reports entitled "Field Tests, Analyses, and Laboratory Tests" [Zwerneman et al., 1996], and "Data Acquisition System for Strain Measurements" ...
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 ...
Statistical models for identification of problematic bridge sites and estimation of approach settlements (FHWA-OK-94-02) 2188
(1995-5)
Bridge approach settlement is caused by the differential movements of the bridge abutment and the approach pavement. The resulting unsafe riding surface not only requires frequent and costly maintenance but also leads to ...
Fatigue Assessment of Bridge Members Based on In-Service Stresses interim report no. 1 August 1996 (FHWA-OK-95-07) 2196
(1996-8)
Construction problems involving poor welding practice occurred during widening of the U.S. 69 bridge over the South Canadian River. As a result of these problems, cc>ncerns developed regarding the remaining fatigue life ...
Silane penetrating waterproofing sealers (FHWA-OK-96-09)
(1996-11)
The Oklahoma Department of Transportation has been applying silane penetrating water sealers since the late 1970' s to prevent the intrusion of chloride contaminated water in bridge decks. This contaminated moisture causes ...

(1997-7)
This publication consists of a listing of experimental products that are being, or have been, evaluated by The Oklahoma Department of Transportation, or other transportation agencies. The listing is continuously updated ...
FEABAS A user friendly software for prediction of bridge approach settlement (FHWA-OK-95-03) 2188
(1995-5)
Bridge approach settlement is a major problem in highway design as well as maintenance. It creates an unsafe and uncomfortable riding surface. This report presents the details of a software that was developed at the ...
Resilient moduli of raw and stabilized aggregate bases and evaluation of layer coefficients for AASHTO flexible pavement design volume I (FHWA-OK-98-05) 2199
(1998-8)
A comprehensive study involving laboratory testing of resilient moduli (MR) of aggregate materials, determination of layer coefficients, and their application in AASHTO flexible pavement design was conducted. Three coarse ...
Evaluation of structural steel coatings using laboratory methodology - final report (OK-98-04) 2292
(1998-4)
Five structural steel coating systems (Wasser, Carboline, Valspar, Watson and Superior) were selected for evaluation and sent to Corrosion Control Consultants & Labs, Incorporated (CCCL) to be tested. In addition to the ...
