Cold mix asphalt aggregate paving material
View Patent ↗The present disclosure generally relates to formulations for, and methods of making and using, an asphalt aggregate paving material without heating the material.
1. A cold mix asphalt aggregate paving material comprising:
more than one aggregate;
an emulsion; and
water at 2-4% greater than aggregate surface saturation.
2. The cold mix asphalt aggregate paving material of claim 1 , wherein said more than one aggregate and said emulsion are combined to form an emulsion-coated aggregate blend.
3. The cold mix asphalt aggregate paving material of claim 1 , wherein said emulsion is a polymer-modified cationic slow setting emulsified asphalt with a solvent-free rejuvenator.
4. The cold mix asphalt aggregate paving material of claim 1 , wherein said emulsion is greater than 1% by weight of the more than one aggregate.
5. The cold mix asphalt aggregate paving material of claim 1 , wherein said emulsion is less than 8% by weight of the more than one aggregate.
6. The cold mix asphalt aggregate paving material of claim 1 , wherein of said more than one aggregate, 100% passes through a 19.0-mm sieve, 98-100% passes through a 12.7-mm sieve, 85-100% passes through a 9.51-mm sieve, 50-70% passes through a 4.76-mm sieve, 28-40% passes through a 0.595-mm sieve, 2-15% passes through a 0.297-mm sieve, and 0-5% passes through a 0.074-mm sieve.
