Abstract

The invention belongs to the technical field of emulsified asphalt and relates to a bio-based non-viscous wheel tack coat and a preparation method thereof. The method comprises the preparation steps of mixing hard asphalt with biomass heavy oil under the shear conditions of 120-130 DEG C and 3,000-5,000r / min according to ratio for 20-30min to obtain biological asphalt; shearing the biological asphalt, epoxy resin and nano silicon dioxide at 110-120 DEG C evenly to obtain modified biological asphalt; and preparing the bio-based non-viscous wheel tack coat from the modified biological asphalt at 130-140 DEG C and an emulsifier solution at 50-60 DEG C through a colloid mill according to the ratio. Compared with the prior art, the tack coat prepared through the method is high in emulsifying speed, non-viscous to a wheel, and not easy to fall off, enough interlayer bonding strength can be provided, the interlayer disease generated by interlayer shear force of an asphalt pavement is effectively improved, and the bio-based non-viscous wheel tack coat is low in cost and has important application value and economic benefit.

Description

technical field

[0001] The invention belongs to the technical field of emulsified asphalt, in particular to a bio-based non-stick wheel tack oil and a preparation method thereof. Background technique

[0002] The sticky layer is a thin layer of asphalt material that is sprinkled to strengthen the bonding effect between the layers in the asphalt pavement structure. Its function is to make the layers of the asphalt pavement, the new asphalt layer and the old asphalt pavement approximately bonded into a whole. When the asphalt pavement is repeatedly acted by the vertical and horizontal loads caused by the vehicle load, the bonding material can resist various stresses generated inside the pavement structure, especially the shear force between layers, which can ensure that the asphalt There will be no damage such as slippage between the pavement layers, thereby ensuring the excellent road performance of the asphalt pavement and prolonging its service life.
