• Abstract:
  The report documents the long-term performance and cost effectiveness of four rehabilitation ; treatments in a mostly homogenous environment. The underlying subbase and subgrade soils, traffic ; volume, existing pavement structure and ambient conditions are similar in all sections. The Vermont ; Agency of Transportation specified the construction of a standard overlay, cold recycled pavement, and ; reclaimed stabilized base along US Route 7 in the towns of Dorset, Mt. Tabor and Danby in 1996 and ; 1997. Each of these treatments is intended to address various pavement distresses. ; Testing and surveillance measures included annual pavement surveys prior to and following ; construction along with the collection of IRI reading by Pavement Management with the use of a road ; profiler. Sixteen 100’ test sections were established throughout the length of the project. Associated ; pavement surveys included the documentation of cracking and rutting. Cracking was further analyzed ; for total cracking, fatigue cracking and transverse cracking. Thirteen years following construction, only ; three of the six pavement composites display measurable amounts of fatigue and transverse cracking ; including the standard overlay, 3-inch CIR with 1½-inch overlay and 4-inch CIR with 1½-inch overlay. ; Two of the more comprehensive treatments, 4-inch CIR and 8-inch RSB with 3¼-inch bituminous ; overlay, displayed the greatest amount of rutting as a function of preconstruction conditions. Through ; the metrics developed in the study, the treatments with the thicker bituminous overlays outperformed ; the thinner overlays.
