Abstract

The invention discloses high-adhesion modified asphalt and a preparation method thereof, and belongs to the technical field of road engineering materials. The raw materials of the high-adhesion modified asphalt comprises 500 parts of base asphalt, 300-400 parts of an additive and 10-20 parts of composite reinforcing fibers, and the composite reinforcing fibers are prepared by compounding basalt fibers and polyester fibers and then being coated with base asphalt thin films. When preparing the high-adhesion modified asphalt, the composite reinforcing fibers are added, so that the adhesion, high-temperature stability, fatigue durability of asphalt pavements are greatly improved, and the asphalt has the properties of low-temperature crack prevention and reflection crack prevention. The tensile, shear, compressive and impact strength are effectively improved, and the thermal stability and low temperature resistance of the asphalt are improved.

Description

technical field

[0001] The invention relates to the technical field of road engineering materials, in particular to a high-viscosity modified asphalt and a preparation method thereof. Background technique

[0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction.

[0003] With the development of China's highway transportation, my country's highway construction is entering a period of rapid development. New conditions such as high speed, heavy load and bearing complex stress have put forward higher requirements for high-grade road surfaces. The traditional densely graded asphalt concrete pavement is prone to problems such as slipping, water drift, sp...
