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.
