PennDot Testing Soy For Use On Roads

PennDot's local office is testing a liquid soy product to be used as a sealant for roadways in the region. The soy product is not yet ready for use but looks promising according to PennDot Engineer Mike McCart. The liquid soy is being tested as a sealant that prevents deterioration of roadways much the same way staining decks improves the life of the wood. McCart said there is no timetable as to when the soy would be available for use on state and local roadways because a key part of the testing is making sure the sealant will last the test of time.
