Understanding A+B bidding patterns and policy implications for ODOT project lettings [Research highlighter]
(Oklahoma City, OK : Oklahoma Department of Transportation, 2016., 2016-12)
Departments of Transportation (DOTs) are challenged with keeping the cost of construction low and ensuring timely project completion. A+B bidding is an innovative contracting design that allows contractors to propose an ...
DRYING SHRINKAGE PROBLEMS IN HIGH PI SUBGRADE SOILS
(2014-1)
The main objective of this study was to investigate the longitudinal cracking in pavements due to drying shrinkage of high PI subgrade soils. The study involved laboartory soil testing and modeling. The shrinkage cracks ...
Vegetative Rehabilitation of Highway Cut Slopes in Eastern Oklahoma (FHWA-OK-11-09 2188)
(2011-9)
Areas of moderate to severe erosion are occurring on highway rights of way in eastern Oklahoma. The silt from this erosion is filling ditch bottoms causing drainage problems ranging from slight to severe. Current vegetative ...
LONG TERM PAVEMENT PERFORMANCE MONITORING OF SIX LTPP SPS-10 SECTIONS IN OKLAHOMA WITH 3D LASER IMAGING (FHWA-OK-19-05 2115)
(2019-12)
Under the LTPP Specific Pavement Study 10 (SPS-10) experiment initiative, the Oklahoma Department of Transportation (ODOT) constructed five warm mix asphalt (WMA) testing sections and one hot mix asphalt (HMA) control ...
Stability and Permeability of Proposed Aggregate Bases in Oklahoma (FHWA-OK-09-05 2196)
(2010-5)
Aggregate base is an important component of a pavement structure. It supports the asphalt concrete (AC) layer and reduces the wheel load-induced stresses on the underlying layers. It also functions as a drainage layer. ...
QC/QA TESTING DIFFERENCES BETWEEN HOT MIX ASPHALT (HMA) AND WARM MIX ASPHALT (WMA) (FHWA-OK-13-02 2218)
(2013-1)
WMA represents a group of technologies which allow a reduction in temperatures at which asphalt mixtures are produced and placed on the road. ODOT Materials Division has conducted preliminary inquiries into QC/QA testing ...
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 ...
