Collision Avoidance System at Intersections (FHWA-OK-09-06 2216)
(2009-12)The number of collisions at urban and rural intersections has been on the rise in spite of technological innovations and advancements for vehicle safety. It has been reported that nearly a third of all reported crashes ... -
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. ... -
Tube Suction Test for Evaluating Durability of Cementitiously Stabilized Soils (FHWA-OK-11-05 2215)
(2011-6)In a comprehensive laboratory study, different tests namely, unconfined compressive strength (UCS) at the end of freeze-thaw/wet-dry (F-T/W-D) cycles, resilient modulus (Mr) at the end of F-T/W-D cycles, vacuum saturation, ... -
Use of the dynamic cone penetrometer to verify and correlate with soil subgrade and aggregate base CBR values for the purposes of design of low volume traffic asphalt concete roadways
(March, 199)The use of the Dynamic Cone Penetrometer (DCP) has increased dramatically over the past several years. The primary reason for the increased use stems from improvements to the device and the development of correlation equations ... -
VALIDATION AND REFINEMENT OF CHEMICAL STABILIZATION PROCEDURES FOR PAVEMENT SUBGRADE SOILS IN OKLAHOMA – VOLUME II (FHWA-OK-11-02(2))
(2011-10)For projects involving a chemically stabilized layer as a part of the structural design of the pavement, it is typical to conduct a mix design to assess the additive content needed to achieve a certain unconfined compressive ...
