Fiber compound regenerative asphalt concrete

Abstract

The invention provides fiber compound regenerative asphalt concrete, which is prepared from the following ingredients (by weight): 30 parts of 0-5mm regenerative asphalt concrete RAP, 25 parts of 5-10 mm regenerative asphalt concrete RAP, 28 parts of 10-30 mm regenerative asphalt concrete RAP, 15 parts of 10-30 mm new aggregate, 2 parts of mineral powder, 1.5 parts of cement, 4 parts of emulsified asphalt, 1 part of a regenerant and 1.2 parts of glass fiber. The glass fiber of 6 mm long is added to improve material performance of a cold recycled mixture. The glass fiber is obviously better than other fibers. The special fiber has obviously more excellent dispersion effect in the cold recycled mixture than other fibers, and the regenerative mixture is smooth to discharge. The fiber compound regenerative asphalt concrete provided by the invention has obviously more excellent material performance than the code requirements. Tension strength, namely cleavage strength, of the mixture is raised. Material anti-cracking ability is more excellent, reflection crack resistance is stronger, the material is more compact, moisture damage resistance is stronger, and durability is better.

Description

technical field [0001] The invention belongs to the field of building materials. More specifically, the present invention relates to a fiber composite recycled asphalt concrete. Background technique [0002] At present, the material composition of emulsified asphalt plant mixed cold recycled mixture is mainly RAP material, emulsified asphalt, cement and water. The performance of the mixture material is limited, and it has not played a good role. Contents of the invention [0003] In order to solve the above problems, the present invention provides a fiber composite recycled asphalt concrete, which is prepared from the following components by weight: [0004] 30 parts of 0-5mm recycled asphalt concrete RAP, 25 parts of 5-10mm recycled asphalt concrete RAP, 28 parts of 10-30mm recycled asphalt concrete RAP, 15 parts of 10-30mm new aggregate, 2 parts of mineral powder, 1.5 parts of cement, 4 parts of emulsified asphalt, And 1 part of regeneration agent, and 1.2 parts of gla...
