The pavement engineering community has recently been introduced to a number of nontraditional products intended for uses as surface sealers for bituminous pavements. Many new products use agricultural-based components and little is known regarding their effect on bituminous pavement performance. Several nontraditional and “bio-based” fog sealants were applied to bituminous shoulder sections less than two years old. A field evaluation was performed over a three-year period, and included documenting installation, application rates, equipment types, locations, and sampling of the product. Annual field reviews were performed, including tests of pavement marking reflectivity, friction, cracking, appearance, and permeability. Application rates varied from 0.015 to 0.10 gallons per square yard according to the product used. It was found that during the evaluation period, the applications provided various levels of waterproofing, and some test sections experienced less thermal cracking than the control. Nontraditional product applications did not adversely affect the long-term visibility of pavement markings or the overall pavement performance. Laboratory testing of pavement cores showed similar high- and low-temperature performance relative to the control.
