• In addition to our preservation program, the state also has a maintenance-driven resurfacing program which covers approximately $70M annually.
Treatments Used To Date • Mill and Overlay HMA/PMA • Ultra-Thin Bonded HMA/PMA • Microsurfacing • Rubberized Chip Seal Stress-Absorbing Membrane Interlayer (SAMI) • Asphalt-Rubber Gap-Graded Mix • Thin Friction Wearing Course (Mahoney Mix) • High Friction Surface Treatment
Ultra-Thin Bonded PMA (picture – 2016, treatment – 2014) I-91 in Hartford/Windsor, CT
Treatments Used To Date • Rubberized Chip Seal • Fog Seal • Surface, Partial Depth, and Full Depth Patching • Crack Sealing and Filling • Micro-milling • Diamond Grinding
Rubberized Chip Seal (2011/2016) Route 89 in Mansfield, CT
Challenge Encountered • Change in Contracting Method ▫ Delivering preservation projects through vendor in place contract ▫ Developed contract documents with all treatments proposed ▫ Inspection and oversite through maintenance staff as opposed to construction staff ▫ Training held to help get everyone on board and up to speed ▫ More involvement from Pavement Unit staff from project selection to construction completion
Program Achievement • Broader Use of True Pavement Preservation Treatments for 2018 ▫ Ultra-Thin Bonded PMA Fog Seal ▫ Rubberized Chip Seal ▫ Crack Sealing
Ultra-Thin Bonded PMA (2016) Shoulders – Fog & Sand Seal I-84 in Cheshire, CT

• Lack of variety in preservation treatment types for 2017 is mainly due to challenges associated with changes to the contracting method. We anticipate the inclusion of additional, true preservation treatments for 2018 and future use.
