Abstract
Embodiments of the present disclosure are generally related to asphalt compositions, and particularly to enhanced asphalt compositions and methods and systems for manufacturing the same. The enhanced asphalt compositions include both a silane additive and a calcium composition. The silane additive includes benzyl alcohol and at least one organosilane. The enhanced asphalt compositions of the present invention have improved anti-stripping properties, but the quantities of calcium composition and silane additive required are less than the quantities necessary to prepare previously known asphalt compositions with improved anti-stripping properties.
Claims20
A method for manufacturing an enhanced asphalt composition, comprising:
- providing an asphalt composition container;
- adding an aggregate to the asphalt composition container, the aggregate comprising between about 0.1 wt % and 0.8 wt % of a calcium composition;
- adding a binder to the asphalt composition container, the binder comprising between about 0.01 wt % and about 0.15 wt % of a silane additive;
- and
- mixing the aggregate and the binder together under heat for a predetermined length of time to form the enhanced asphalt composition,
- wherein the silane additive comprises benzyl alcohol and at least one organosilane, and
- wherein the calcium composition comprises at least one compound selected from the group consisting of calcium hydroxide, calcium oxide, an anhydrous calcium silicate, and anhydrous calcium sulfate.
An enhanced asphalt composition, comprising:
- an aggregate, comprising between about 0.1 wt % and 0.8 wt % of a calcium composition;
- and
- a binder, comprising between about 0.01 wt % and about 0.15 wt % of a silane additive,
- wherein the silane additive comprises benzyl alcohol and at least one organosilane, and
- wherein the calcium composition comprises at least one compound selected from the group consisting of calcium hydroxide, calcium oxide, an anhydrous calcium silicate, and anhydrous calcium sulfate.
An enhanced asphalt manufacturing system, comprising:
- an asphalt receptacle;
- at least one heating element, configured to heat the asphalt receptacle and contents inside the asphalt receptacle;
- an enhanced asphalt composition disposed inside the asphalt receptacle, the enhanced asphalt composition comprising:
- an aggregate, comprising between about 0.1 wt % and about 0.75 wt % of a calcium composition;
- and
- a binder, comprising between about 0.01 wt % and about 0.15 wt % of a silane additive;
- and
- a dispensing applicator, operatively interconnected with the asphalt receptacle and configured to convey the enhanced asphalt composition from the asphalt receptacle to a work surface,
- wherein the silane additive comprises benzyl alcohol and at least one organosilane, and
- wherein the calcium composition comprises at least one compound selected from the group consisting of calcium hydroxide, calcium oxide, an anhydrous calcium silicate, and anhydrous calcium sulfate.
