These 60 mil thick membranes are composed of rubberized asphalt laminated to a waterproof polyethylene film. Early projects the ar that phoenix used consisted of crumb rubber or ground up used tires mixed with liquid asphalt binder. Ge 2 1 2 x 1 9 x 2 18 8 1 4 26 9. That number is expected to grow more and more states are starting to see the benefits of rubber in asphalt and recently have been taking on the old technology and mastering the process.

Adding 4 inches to the existing roadway elevation may not be practical. A higher in place cost is one of the main disadvantages of sheets. The disadvantage of rubber modified asphalt is associated with the preparation process during heated storage. The cost of the material itself is likely to be greater on a square foot.

Rubber from scrap tires or other sources is grinded and blended with asphalt cement to beneficially modify the properties of asphalt forming rubber modified asphalt binder asphalt rubber binder or used as a aggregate substitute in an asphalt concrete paving mixture. In the last decade a number of states and federal agencies have run tests on its durability. This study examined the swelling principle of desulfurized rubber asphalt dra. Another waterproofing material is rubberized asphalt.
