The product is a soy derivative and has been marketed todrastically reduce the infiltration of air and water into pavement. The company further claims that the oils increase theflexibility of aged, brittle pavement, deterring reflective cracking. The product contains approximately 15% polymers, whichthe company claims increase the resistance to raveling, rutting, and cracking. This research project will evaluate RePlay\ue2\u20ac\u2122seffectiveness at reducing permeability without unacceptably reducing durability or skid resistance
