Abstract:

This report presents the findings of a field study in Maine, constructed during summer 2012 using

two different joint technologies and an infrared heater. MaineDOT has previously used an infrared

heater and notch-wedge apparatus to improve longitudinal joint density on a trial basis. The goal of

infrared joint heaters is to increase the temperature of the existing HMA material being paved

against, in turn reducing the viscosity of the material and allowing the material to be compacted by

the rollers. In contrast, the notch-wedge apparatus is designed to construct a precompacted, tapered

mat edge with an adjustable vertical “notch” at the top and bottom of the lift.
