Abstract

The invention discloses an anti-freezing asphalt concrete composite, and relates to the technical field of roads. The anti-freezing asphalt concrete composite is prepared from, by weight, 20-25 partsof crushed crude pearlite, 10-15 parts of coal ash, 50-65 parts of asphalt, 30-35 parts of building stones, 30-35 parts of stone sand, 8-17 parts of organic silicon resin, 8-17 parts of polyurethane,0.3-0.5 part of PVC heat stabilizer and 1-3 parts of polyimide. When the anti-freezing asphalt concrete composite is adopted for road pavement, the anti-freezing capability of a road surface is enhanced, and the phenomenon that the road surface is damaged by freezing is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of roads, and in particular relates to an antifreeze asphalt concrete composition 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. The asphalt structural layer of asphalt pavement itself belongs to the category of flexible pavement, but in addition to flexible materials, the base layer can also use rigid cement concrete or semi-rigid hydraulic materials. [0003] In our country, the application of asphalt pavement is very extensive, but most of the current asphalt pavements have a problem, especially in winter, when en...
