Abstract
A fuel-resistant liquid asphalt binder including a composition of fatty amine derivatives for improving the flowability and workability of a bituminous asphalt mix. The fuel-resistant liquid asphalt binder may include 0.4 wt % to 0.7 wt % of a composition of fatty amine derivatives, 2 wt % to 5 wt % styrene-butadiene-styrene, and 2 wt % to 5 wt % high acetate content ethyl vinyl acetate. The fuel-resistant liquid asphalt binder may be mixed with an aggregate to form a bituminous asphalt mix at temperatures ranging from 330° F. to 280° F.

A fuel-resistant liquid asphalt binder comprising:
- a liquid asphalt binder base having a concentration in the range of 89.3 wt % to 95.6 wt %;
- styrene-butadiene-styrene having a concentration in the range of 2 wt % to 5 wt %;
- high acetate content ethyl vinyl acetate having a concentration in the range of 2 wt % to 5 wt %;
- and
- a composition of fatty amine derivatives having a concentration in the range of 0.4 wt % to 0.7 wt %.
A bituminous asphalt mix comprising:
- a fuel-resistant liquid asphalt binder comprising:
- a liquid asphalt binder base having a concentration in the range of 89.3 wt % to 95.6 wt %;
- styrene-butadiene-styrene having a concentration in the range of 2 wt % to 5 wt %;
- high acetate content ethyl vinyl acetate having a concentration in the range of 2 wt % to 5 wt %;
- and
- a composition of fatty amine derivatives having a concentration in the range of 0.4 wt % to 0.7 wt %.
- air voids;
- and
- an aggregate.
A method of making a fuel-resistant liquid asphalt binder, the method comprising:
- mixing a liquid asphalt binder base and styrene-butadiene-styrene in a high shear mixer, thereby forming a first mixture;
- adding at least one cross-linking agent to the first mixture;
- curing the first mixture;
- mixing the first mixture with high acetate content ethyl vinyl acetate in a high shear mixer;
- thereby forming a second mixture;
- and
- mixing a composition of fatty amine derivatives with the second mixture, thereby forming the fuel-resistant liquid asphalt binder;
- wherein the liquid asphalt binder base has a concentration in the range of 89.3 wt % to 95.6 wt % in the fuel-resistant liquid asphalt binder;
- the styrene-butadiene-styrene has a concentration in the range of 2 wt % to 5 wt % in the fuel-resistant liquid asphalt binder;
- the high acetate content ethyl vinyl acetate has a concentration in the range of 2 wt % to 5 wt % in the fuel-resistant liquid asphalt binder;
- and the composition of fatty amine derivatives has a concentration in the range of 0.4 wt % to 0.7 wt % in the fuel-resistant liquid asphalt binder.
