Abstract

The invention provides a cold-mixing and cold-paving asphalt additive and a preparation method of an asphalt mixture, which are used for solving the limitation of the cold-mixing and cold-paving asphalt mixture on the construction temperature in the prior art. The cold-mixing and cold-paving asphalt mixture disclosed by the invention meets the technical requirements that the initial strength is greater than 3.0 KN and the track dynamic stability is greater than 1000 times/mm, and meets the requirements of immediately opening traffic conditions and later road use after construction; the averageresidual stability is up to 90% or above, and the requirement for water damage resistance is met; and production construction can be carried out around the clock (no ice is formed at the temperatureof 40 DEG C below zero to 20 DEG C below zero). The method can be applied to each layer of a pavement structure.

Description

technical field [0001] The invention belongs to the technical field of road engineering materials, and in particular relates to a cold-mixed and cold-paved asphalt additive and a preparation method of asphalt mixture. 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] A large number of asphalt is used as the pavement material for highway pavement or bridge deck, but because asphalt is a thermoplastic material, the asphalt pavement material is usually used in the construction process by hot mixing, and the production process of this hot mixing method is complicated and often requires large equipment , and consume...
