Abstract:Performance of Hot Mix Asphalt (HMA) longitudinal joints have been an
item of increasing scrutiny in Connecticut. The traditional butt joint
has typically been the method used in Connecticut. These joints have
been reportedly opening up creating a longitudinal crack at the joint
thus contributing significantly to the premature failure of the wearing
surface. It has been widely speculated that alternative longitudinal
joint construction methods could be employed to reduce the rate at
which joints fail. Here, the Notched Wedge Joint is investigated along
with the traditionally used butt joint for comparison purposes. Two
resurfacing projects were constructed in Connecticut during the 2006
paving season that utilized the notched wedge joint construction
method. These projects were investigated as to their nuclear density
and volumetric density from cut cores along the longitudinal joints.
Also investigated during the 2006 construction season were several
resurfacing projects which utilized the traditional butt joint.
