Programming rehabilitation for rural highways was difficult under the existing rehabilitation policies. To minimize the required maintenance effort on these highways, and maximize the available rehabilitation dollars, IDOT initiated a single pass, thin lift bituminous concrete overlay policy. The new rehabilitation strategy, Surface Maintenance at the Right Time (SMART), was designed for rural highways with low levels of traffic, which otherwise probably would not be rehabilitated under the current rehabilitation policy. Pavements chosen for rehabilitation under SMART ideally would have age-related distresses, with few indications of structural failure. Project rehabilitation consists of pavement patching, milling, and reflective crack control treatments where necessary, followed by a 30- to 40-mm (1.25- to 1.50-in.) bituminous concrete overlay. The SMART program has been very successful. Performance is high; rehabilitations are expected to last 7 to 10 years. Through proper project selection and construction, this program is a cost-effective method for reducing the number of highway kilometers needing rehabilitation.
