The objective of this research study is to develop an addendum to NAPA’s QIP-128 publication
titled “Best Practices for Emulsion Tack Coats” that will address the tracking of tack coats. The
addendum will identify and report on the latest technologies, methods, and/or practices that
can be employed to address tracking of tack coat materials.
Specification Updates
SC-M 404 – Addition of the Auto Rice Controller to the equipment list for field labs.
SC-M 406 – Changing Organosilane LASA materials from 0.15 to 0.10 min dosage.

Description:
The NCAT Pavement Test Track has been used by state DOTs to execute innovative, relevant, and implementable research for over 20 years. Thinlays have played an important part in the Track research program since the 2003 (2nd 3-year) research cycle. The role of thinlays was expanded in 2012 in support of off-Track pavement preservation research. Since that time, thinlays have been placed on the Track, on off-Track southern (low and high traffic) pavement preservation sections, and on northern (low and high traffic) pavement preservation sections in support of the NCAT+MnROAD Pavement Research Partnership. Properly designed and well built thinlays have proven themselves to be both rut and crack resistant, and have provided a riding surface with a safe level of surface friction.
