As Good as New: Indiana DOT Debuts Recycling Method on Rural Trucking Corridor

When the Indiana Department of Transportation (INDOT) recognized the need to replace and widen an 8.6-mile stretch of S.R. 101 in rural Allen County, in order to address damage from years of heavy truck and traffic and to accommodate horse-and-buggy traffic from the local Amish population, they opted for a full-depth reclamation (FDR) method, using recycled material from the existing asphalt at a reduced cost. A recycling process that had not been attempted before in the state was utilized - cold central plant recycling (CCPR), which consists of a mixture of reclaimed asphalt pavement (RAP), millings from existing stockpiles or asphalt pavements, asphalt emulsion, water and other additives. The details of the construction process in terms of road closures, as well as mix design, are presented in this article.
