Kerry Werner with the City of Eugene will present Strengthening
Road Subgrades with Cement Slurry Paste. In the pursuit of speed,
sustainability, strength and safety; the City of Eugene developed a new
technique for strengthening road base and subgrade material by blending cement
paste with poor soils to form a strong subgrade without using traditional
powder cement or remove and replace method.
This presentation will describe the design, concept verification, specifications,
construction and testing of the In-place Cement Treated Base process for
reconstruction of Shasta Loop & Firland Street using a cement slurry paste.
