VALIDATION AND REFINEMENT OF CHEMICAL STABILIZATION PROCEDURES FOR PAVEMENT SUBGRADE SOILS IN OKLAHOMA – VOLUME I FINAL REPORT (FHWA-OK-11-02 2207)
(2011-7)
Additions of byproduct chemicals, such as fly ash or cement kiln dust, have been shown to increase the unconfined compression strength (UCS) of soils. To be considered effective, the soil must exhibit a strength increase ...
EVALUATION OF PERFORMANCE OF ASPHALT PAVEMENTS CONSTRUCTED USING INTELLIGENT COMPACTION TECHNIQUES
(2014-10)
The long-term performance of asphalt pavements depends on the quality of the subgrade and asphalt layers. Intelligent compaction methods continuously monitor the modulus/stiffness of subgrade and asphalt layers during ...
