Abstract:The primary objective of this evaluation is to determine the effectiveness of the Joint Maker and Precompaction
Screed, both developed by TransTech Systems, Inc., in achieving higher and more uniform density across the mat of
a rehabilitated Hot Mix Asphalt pavement by increasing the density in the problem areas. The problem areas consist
of the rutted areas and the longitudinal joint edges. TransTech Systems, Inc. has developed these two attachments
for the benefit of doing a single rehabilitation overlay without requiring preparatory work to the problem areas. The
major advantage would be derived from not having to cold mill or preliminarily level the existing rutted areas prior
to the surface overlay. This would ultimately reduce project costs.
