Biorestor contains polymers to protect AC binder from oxidation

Today's refineries have become very good at extracting value from the crude oil it refines. Where asphalt cement was the lowest price product produced 30 years ago by the refinery it has now reached price levels comparable to the fuels they produce. The value of the asphalt cement alone has gone from $150 per liquid ton in 2000 to $700 per ton in 2008. That brings the cost of the asphalt cement in 1 square yard 1 1/2" thick from $0.75 in 2000 to $3.50 in 2007. These costs have leveled off but understand asphalt pavement costs are directly related to crude oil.

Today's asphalt cements show a significant loss of value in viscosity and penetration as soon as they are mixed and before they are loaded to be delivered to the project site. Over 50% of the penetration value has been lost in this mixing process. This hardening effect of the asphalt cement affects the flexibility of the road system and end resulting performance. New Federal Highway design specifies asphalt cement performance requirements for highway work that requires the addition of polymers which will help with high traffic demands and longer performance.

Biorestor adds agricultural oils and polymers to the asphalt cement in the top 1/2" of the pavement where the tire meets the road so to speak. Here is where the oxidation process starts. Water and UV begins the process that result in loss of flexibility resulting in surface ravel and cracking.
