Summary:
After six years of service, the asphalt-rubber concrete 1) modified ConnDOT Class 2) mix on Route 79, in Madison, has
performed better than the standard Class 2 control mix.  This determination is made on the basis of longitudinal cracking,
which is the only distress of significance to develop during the period.  The skid resistance is somewhat lower on the
asphalt-rubber mix than the control, but the friction level has remained adequate at this location.  In situations where low
skid numbers traditionally occur due to poor geometry and high traffic volume, the asphalt-rubber mix might result in
less than desirable friction levels.
