• Abstract:
  In the 60’s, 70’s, and 80’s, many Illinois local road agencies successfully used “conventional” asphalt ; emulsions for In-Place Recycling to produce Emulsion-Aggregate-Mixtures (EAMs). In more recent years, these ; emulsions have not been widely used for Cold-In-Place Recycling construction. A major constraint to the continued ; utilization of EAMs was the long “drying time” (loss of moisture following mixing and prior to compaction) associated ; with the process. ; The use of “foamed-asphalt” and improved emulsion compositions (called “engineered emulsions”) has ; alleviated (some suggest eliminated) some of the concerns that have limited the use of emulsions for Cold-In-Place ; Recycling. ; The project objective is to evaluate and contribute to the facilitation and implementation of currently available ; CIR&FDRwAP (ColdIn-Place Recycling and Full-Depth Recycling with Asphalt Products) technology. ; An “information/data” survey was conducted, ten selected CI&FDIRwAP projects were documented and ; evaluated, mixture properties (modulus, strength, fatigue) were established, thickness design options were evaluated, ; mixture design approaches were evaluated, and construction aspects considered. ; The mixture design procedures currently used by SemMaterials for Engineered Emulsions and the Wirtgen ; procedure (or procedures similar to the Wirtgen procedure) for foamed asphalt mixtures are recommended for interim ; use. ; Typical successfully used specifications for Full-Depth Recycling and Cold-in-Place-Recycling are presented. ; It is recommended that a “Working Group” be established to refine/further adapt the mixture design ; procedures and construction specifications for Illinois Local Roads and Streets utilization. ; Project information/findings/results support the recommendation that the CIR&FDRwAP process be ; considered a “standard procedure.” It currently is incorporated into a project as an “experimental feature.”
