Abstract
A petroleum distillate-free or essentially petroleum distillate-free prime coat material for application to absorptive surfaces, such as untreated road or street surfaces, which is designed to penetrate, bond, and stabilize such existing surfaces and to promote adhesion between such surfaces and construction courses that follow. This type of material is also often used as a dust palliative. For this purpose, the material is applied to an untreated surface to control dust.
Claims20
An essentially petroleum distillate-free prime coat emulsion, comprising 0 to about 40% asphalt cement, about 5% to about 45% tall oil, tall oil fractions, or mixtures thereof, the tall oil, fractions, or mixtures thereof being present in sufficient quantity that it comprises at least 20%, by weight, of the combined weight of the asphalt cement and tall oil, fractions or mixtures, about 40% to about 65% water, and about 0.2% to about 3% of a strong base, the tall oil, fractions, or mixtures thereof and the strong base functioning as an emulsifier or emulsifying agent.
An essentially petroleum distillate-free prime coat emulsion, comprising about 10% to about 40% asphalt cement, about 3% to about 30% tall oil, tall oil fractions, or mixtures thereof, the tall oil, fractions, or mixtures thereof being present in sufficient quantity that it comprises at least 20%, by weight, of the combined weight of the asphalt cement and tall oil, fractions or mixtures, about 40% to about 65% water, and about 0.2% to about 3% of a strong base, the tall oil, fractions, or mixtures thereof and the strong base functioning as an emulsifier or emulsifying agent.
An essentially petroleum distillate-free prime coat emulsion, comprising about 30% to about 50% tall oil, tall oil fractions or mixtures thereof, about 50% to about 70% water, and about 0.1% to about 5% of a strong base, the tall oil, fractions or mixtures there of and the strong base functioning as an emulsifier or emulsifying agent.
An essentially petroleum distillate-free prime coat emulsion, comprising about 5% to about 25% tall oil, tall oil fractions or mixtures thereof, about 15% to about 35% of essentially petroleum distillate-free petroleum distillation residue, the tall oil, fractions, or mixtures thereof being present in sufficient quantity that it comprises at least 20%, by weight, of the combined weight of the tall oil, fractions or mixtures and the essentially petroleum distillate-free petroleum distillation residue, about 50% to about 70% water, and about 0.1% to about 2% of a strong base, the tall oil, fractions, or mixtures thereof and the strong base functioning as an emulsifier or emulsifying agent.
