Implementation of Slag Stabilized Blended Calcium Sulfate (BCS) in a Pavement Structure

摘要

This research project was the field implementation follow up to laboratory research conducted at LTRC. The research met a need and benefited District 61 staff by allowing an alternative to the removal and replacement of the old, non-standard blended calcium sulfate (BCS) found on site. The researchers used the previous research to draft, finalize, approve, and implement specifications to allow for the stabilization of BCS with ground granulated blast furnace slag grade 120 (slag) on the shoulders of US 61 just south of LA 22 in Sorrento, LA. Two specifications were used. The first addressed the inplace stabilization of BCS with slag. The second specification addressed a market-driven implementation of the research, specifically the applicability of Honeywells fines material treated with slag in a pugmill for use as base material.
