PROJECT PLANS AND SPECIFICATIONS
BIDDER'S INQUIRY SUBMITTAL FORM
Plan Sheet / Specification Reference= 10-1.22 RUBBERIZED EMULSION AGGREGATE SLURRY
Q-1. Why does the specification call for the patented/proprietary material REAS by Pertochem Marketing Inc? There are other manufacturers that can produce a non-proprietary rubberized polymer modified emulsion (RPME). Why is Caltrans eliminating potential bidders of non-proprietary products from this project by specifying sole-sourced REAS. Caltrans has already bid one job for a generic rubberized slurry seal in D-7. It is not clear whether other materials can be used. It is not Caltrans normal policy to require patented materials when there are other equal materials that can be used. Why is Caltrans showing favoritism toward Petrochem Marketing Inc.. This REAS specification has not been reviewed and approved by the appropriate Slurry Seal and Mircosurfacing PPTG Task Group. This also is not per the Caltrans specification development process. This is an unfair bidding process.
Q-2. REAS has never been bid and used with a type III aggregate. How is the contractor supposed to bid and guarantee the product when it has never been used by the department. It is our understanding that Caltrans has only put out one project to bid with the generic rubberized slurry and it was a type II aggregate, which has some history in city and county use.
