Claims13
An asphalt cement emulsion comprising:
- i) droplets of rubber-modified asphalt cement, characterized in that:
- a) the droplets have a diameter of less than 20 microns;
- b) the rubber-modified asphalt cement is pre-treated with one or more emulsifiers comprising an amine compound;
- and
- c) rubber in the rubber-modified asphalt cement has an average size of less than 1 micron;
- ii) water;
- and
- iii) clay,
- wherein the asphalt cement emulsion undergoes a change in viscosity of less than 10% over a temperature range of 40-140° F.
