Abstract
The present invention relates to a basalt fiber reinforced asphalt concrete, which includes: an asphalt material with a penetration grade between 40-300 at room temperature, selected from one of an asphalt mortar, an oil-soluble asphalt, an emulsified asphalt, and a modified asphalt; an aggregate having a first volume percentage between 50-80%; a basalt fiber reinforcement with a second volume percentage between 0.1-0.9%; and a chemical admixture for asphalt concrete used to adjust the properties of the basalt fiber reinforced asphalt concrete.
Claims6
A basalt fiber reinforced asphalt concrete, comprising:
- an asphalt material with a penetration grade between 40-300 at room temperature, selected from one of an asphalt mortar, an oil-soluble asphalt, an emulsified asphalt, and a modified asphalt;
- an aggregate having a first volume percentage between 50-80%;
- a basalt fiber reinforcement having a length between 3-6 mm and a second volume percentage between 0.5% and 0.9% and configured to provide a restraint force to the basalt fiber reinforced asphalt concrete for reducing crack width and restraining crack propagation;
- and
- a chemical admixture for asphalt concrete used to adjust the properties of the basalt fiber reinforced asphalt concrete,
- wherein the basalt fiber reinforced asphalt concrete has a CT Index value between 1,000 and 3,850 in an IDEAL-CT test.
