Claims21
A binder additive, comprising:
- a volatile solvent additive comprising diesel fuel;
- a base asphalt softener additive comprising maltenes;
- and
- a hydrocarbon absorber additive comprising gilsonite, the hydrocarbon absorber additive being configured to absorb at least some volatile hydrocarbon fractions of the volatile solvent additive.
1 more element
An asphalt concrete, comprising:
- aggregate;
- and
- a binder additive comprising base asphalt and at least one additive, the at least one additive configured to volatile hydrocarbon fractions and controllably release the volatile hydrocarbon fractions.
A method for preparing and using asphalt concrete, the method comprising:
- adding a binder to an aggregate to form a mix;
- allowing the mix to be stockpiled for a time period within a range from one hour to one year;
- within a temperature range from 20° F. and 120° F., compacting the mix into an asphalt concrete formation;
- and
- allowing the asphalt concrete formation to cure and harden.
2 more elements
