Validation of Portable Handheld X-Ray Fluorescence (PHXRF) on Stabilized Subgrade Projects for Construction Quality Control and Geotechnical Forensic Investigations
(2016-05-13)
Problematic subgrade soils are often strengthened through pozzolanic reactions and/or cementing using various types of chemical stabilizers, such as lime, cement kiln dust, and fly ash. The amount of stabilizer needed for ...
THE USE OF RESISTIVITY TESTING FOR QUALITY CONTROL OF CONCRETE MIXTURES (FHWA-OK-20-03)
(2020-08)
This study proposes a new quality control and compliance method for concrete mixture design using standard
surface resistivity testing. This method helps in determining key mixture parameters such as fly ash content
and ...
