It has been claimed that polymerized asphalt emulsion has outstanding characteristics of elasticity, adhesion, and cohesion which allows its use in seal coats in high speed, high volume roads, such as interstate highways. Another use would be on a lower classification road with sharp turns which prevent the use or greatly shortens the life of a regular chip seal. Styrelf is a styrene-butadiene (vulcanized) binder which was added to the base asphalt. Installations varied from an interstate highway with 12,710 average daily traffic (ADT) and 25% trucks to a rural state highway with 1,570 ADT and 15% trucks. Riffe Petroleum Company's product was used in a single installation. It had an ADT of 4,050 with 10% trucks. Owen-Corning Fiberglass Corporation's product was used in a single installation. It had an ADT of 410 with 12% trucks. Polymerized asphalt emulsion that doesn't have the high early adhesion is an inferior product, since the need for adhesion is greatest when the surface is new and tender.
