ABSTRACT:
A method of preventing asphalt and tar from sticking to paving equipment comprises diluting a concentrate with about four to about 50 parts water to one part concentrate and spraying, rolling or brushing the diluted concentrate on the equipment, coating the dilution on equipment prior to its coming into contact with tar or asphalt. The concentrate comprises a fatty acid amide or mixture of fatty acid amides, a fatty acid neutralized with an excess of an alkyl- or alkanol- or mixed-type amine or ammonia, and an optional solvent or solvents. The chief advantages of the instant invention are that the dilutions are viscous, and so prevent the diluted material from running off of the equipment prior to contact with tar or asphalt, and that the diluted material leaves a lubricious film on the surface even after all the water in the diluted film has evaporated.
