Segregation leads to premature failure in roads and lowers the lifespan of a road significantly.

Unnecessary costs, burden on traffic and resources are the results.Studies on segregation are not new but the urgency for implementation of tools measuring and preventing segregation has won worldwide on dynamic. What are the best studies done? Can they be used and adjusted to different states and countries, independent on geographical specific requirements?

This a list of studies done by well-known research and street authorities and their results:

• Texas A&M Transportation Institute Research Project on thermal segregation for over ten years
• Special Specification 3234 and implementation by the State of Texas for measuring segregation
• Research program study and video about segregation and paving quality from the U.S. Transportation Research Board.
• SHRP2 solution sheet Infrared and Radar Technology Test Temperature and Density of Asphalt Pavement Area

Each state and country might have slightly different requirements but the basic data needed is the same. Measuring, locating, and analyzing almost 100% cold spots in asphalt material that leads to early failure of pavement.

Pave-IR and its functionality has been tested and approved by multiple independent institutes like TTI Texas Institute of Transportation, NCAT National Center for Asphalt Technology, State of Texas, State of Minnesota and many more as a valuable tool measuring segregation.

What is the takeaway?

The footwork about measuring segregation and evaluating its benefits has been done over and over. Implementing a paving quality tool like PAVE-IR has the advantage of relying on available test results by well-established research institutes and authority recommendations.

That can save time and money for other road authorities for implementation. It also re-assures contractors that they are using an effective tool for measuring and monitoring segregation, and improving their paving processes.
