What are the types of Rubberized Asphalt projects that Grey County is involved in?
A. The dry system where the rubber is incorporated in the mix as an aggregate. The Cold In-Place Asphalt process where the rubber crumb is laid on the road and mixed with the existing ground up asphalt. The wet system, where the rubber crumb is incorporated into the asphalt cement. This has been done with on site mixing and terminal mixing. The combination wet and dry system where the two systems are combined and used at the same time. This combination system seems to be showing very promising results as we are incorporating the two systems into one and are receiving the combined benefits of both systems into the one mix The dry system where we mix Vestenamer with the rubber crumb to cross link the rubber crumb with the asphalt cement.
