APPLIED APPROACH SLAB SETTLEMENT RESEARCH, DESIGN/CONSTRUCTION (FHWA-OK-13-09 2227)
(2013-8)
Approach embankment settlement is a pervasive problem in Oklahoma and many other states. The bump and/or abrupt slope change poses a danger to traffic and can cause increased dynamic loads on the bridge. Frequent and costly ...
EFFICACY OF ROAD BOND AND CONDOR AS SOIL STABILIZERS (FHWA-OK-13-06 2242)
(2013-8)
The Oklahoma Department of Transportation (ODOT) uses lime-based stabilizers including quick lime, hydrated lime, Class C fly ash (CFA) and cement kiln dust (CKD) to increase bearing capacity of fine-grained subgrade soils ...
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, ...
Overturning Forces at Bridge Abutments and the Interaction of Horizontal Forces from Adjacent Roadways (FHWA-OK-17-03)
(Jan-18)
ODOT is experiencing a number of problems related to the interactions between bridge abutments and adjacent roadways. These problems include expansion joints closing, roller support bearings tilting, and beams pushing ...
Mix design using asphalt millings (FHWA-OK-00-04) 2148
(2000-8)
A field demonstration project was undertaken by the Research & Development Division, Oklahoma Department of Transportation (ODOT), to investigate the performance of an asphalt overlay constructed using recycled asphalt ...
