1. Scrub Seal Emulsions with Rejuvenators

2. Activities of the Spray Group to Date
Developed materials spec and design practice for PMRE
Included one table for all products
Some issues with test parameters so the materials specs have been put on hold
Andrew Hanz and Codrin Daranga have taken the lead on this effort
How to best move forward with the materials spec

3. Purpose of Materials Spec
Make certain that scrub seal spec is effective and properly rejuvenates the cracked asphalt mix
Some products that have been used do not effectively rejuvenate the asphalt mix
The spec needs to be designed to ensure successful applications
The spec should be based on the used of the most successful products used to date

4. What other products should be considered?
Types
Elastic polymers
Non elastic polymers
Bio Based products
Others
Path forward to complete the process
Further testing
