Prototype reinforced soil embankment for reconstruction of US 62 slope failure in Chickasha, OK
(Oklahoma City, OK : Oklahoma Department of Transportation, 2014., 2015-01)
One of the main concerns in internal stability of reinforced soil structures constructed with fine-grained or marginal quality soils is the change in shear strength of the soil-reinforcement interface when the soil gravimetric ...
Analysis of Aggregates and Binders Used for the ODOT Chip Seal Program (FHWA-OK-10-03 2221)
(2010-11)
This project compared the results of laboratory characterization of chip seal aggregate samples for Oklahoma DOT Divisions 1,2,3,5 and 6 with performance data from the Pavement Management System (PMS) database. Binder ...

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 ...
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 ...
