Claims25
A method for making a rubberized chemical emulsion comprising the steps of:
- adjusting the temperature of an anionic material to less than 212.degree. F., wherein the anionic material comprises;
- 35% to 75%, by weight, asphalt, 0.5% to 1,5%, by weight, fatty acid, water, and a base;
- adding rubber and an aliphatic polycarboxylic acid solution to the anionic material, wherein the weight of the rubber is equal to from 1% to 10% of the weight of the anionic material, and wherein the weight of the aliphatic polycarboxylic acid solution is equal to from 0.0% to 1.8% of the weight of the anionic material.
A chemical emulsion made by a process comprising the steps of:
- adjusting the temperature of an anionic material to less than 212.degree. F., wherein the anionic material comprises;
- 35% to 75%, by weight, asphalt, 0.5% to 1,5%, by weight, fatty acid, water, and a base;
- adding rubber and an aliphatic polycarboxylic acid solution to the anionic material, wherein the weight of the rubber is equal to from 1% to 10% of the weight of the anionic material, and wherein the weight of the aliphatic polycarboxylic acid solution is equal to from 0.0% to 1.8% of the weight of the anionic material.
A method for sealing bituminous surfaces comprising the steps of:
- making a rubberized chemical emulsion comprising the steps of;
- adjusting the temperature of an anionic material to less than 212.degree. F., wherein the anionic material comprises;
- 35% to 75%, by weight, asphalt, 0.5% to 1,5%, by weight, fatty acid, water, and a base;
- adding rubber and an aliphatic polycarboxylic acid solution to the anionic material, wherein the weight of the rubber is equal to from 1% to 10% of the weight of the anionic material, and wherein the weight of the aliphatic polycarboxylic acid solution is equal to from 0.0% to 1.8% of the weight of the anionic material;
- and
- applying the chemical emulsion over a bituminous surface.
