Abstract

The invention relates to emulsified asphalt and a preparation method thereof. The emulsified asphalt comprises the following components in percentage by mass: 45%-65% of asphalt, 1%-12% of a modifier,0.4%-3.5% of an emulsifier, 0.1%-0.5% of a separant, 0-4% of hydrochloric acid or phosphoric acid, 0-1% of a stabilizer and the balance of water. The preparation method comprises the following steps:adding the separant, the cellulose and the emulsifier into water to prepare liquid soap, heating the liquid soap and the asphalt, adding the modifier, and carrying out high-speed shearing and grinding on the liquid soap and the asphalt through a colloid mill after the modifier is completely dissolved to obtain the emulsified asphalt. The material has the advantages that the construction efficiency is improved, the integrity of an adhesive layer material is guaranteed, the pavement performance is improved, the storage stability is excellent, special equipment does not need to be purchased additionally, and popularization is easy.

Description

Technical field [0001] The invention belongs to the field of transportation engineering, and specifically relates to an emulsified asphalt with fast demulsification speed, high strength, non-stick wheels and a preparation method thereof. Background technique [0002] According to the definition in the technical specifications for highway asphalt pavement construction, "sticky layer" is a thin layer of asphalt material spread to strengthen the bond between the asphalt layer and the asphalt layer, and between the asphalt layer and the cement concrete pavement. The adhesive layer has the function of sealing gaps in the asphalt pavement structure and ensuring effective bonding between the upper and lower layers, which is of great significance for ensuring the common stress of the pavement structure and extending the service life of the asphalt pavement. However, at the present stage, the most widely used adhesive layer material for highways in my country is still ordinary emulsified ...
