Abstract:A federal aid resurfacing project on CT State Route 2 in Colchester, Lebanon and Bozrah was modified to include Superpave mix designs. Six 3.2 km sections, four Superpave and two ConnDOT Class 1 62.5-mm overlays, were placed between May and September 1997. Two of the Superpave mixes and one Class 1 mix utilized 20% RAP obtained by milling the existing surface layer from Route 2. This is Connecticut's first large-scale Superpave project, as well as the first HMA project in the state where Quality Control was the Contractor's responsibility. This document reports on the construction phase of ConnDOT's research study. FHWA's Mobile Asphalt Laboratory was on-site to perform mix design verification and simulated quality assurance as part of FHWA Demonstration #90. This project is also part of FHWA's LTPP SPS 9A study for "Verification of SHRP Asphalt Specification and Mix Design." 305-m sections within each of the six pavements will continue to be monitored, sampled and tested for at least the next four years.
