Demonstrating Field Use of the Plastic Mold Device on Full-Depth Reclamation Projects in Mississippi

Abstract

This paper documents the use of the 4 x 8 in. plastic mold (PM) device on two full-depth reclamation (FDR) field projects where cement-stabilized material containing large aggregates were used. PM device specimens were assessed to understand project variability as well as investigate potential in-field curing protocols for early-age roadway trafficability. Additionally, PM device specimens were compared with cores to quantify early-age mechanical properties and relationships. The density of PM device specimens and cores were, on average, within 2% of one another. In some cases, on-site curing protocols produced strengths that were not statistically different from cores. Ultimately, the PM device was successfully implemented and capable of producing reliable and repeatable results that captured project variability.
