Abstract

The invention relates to a high-viscosity modified asphalt for water-permeable pavement, comprising: a first component, the first component is asphalt; a second component, the second component is filled particles with a porous structure; The third component, the third component is a colorless cementing material; the second component and the third component are uniformly mixed and then dispersed into the first component. The technical scheme of the invention modifies the asphalt through the permeable concrete and the colorless cementing material, which can increase the water permeability of the asphalt.

Description

technical field [0001] The invention relates to an asphalt material, in particular to a high-viscosity modified asphalt for water-permeable pavement and a preparation method thereof. Background technique [0002] Bitumen is a viscous, black and highly viscous liquid or semisolid found in most crude oils and some natural sediments. Bitumen can also be obtained by refining, mostly as a carefully refined residue from the breakdown of selected crude oils. [0003] Asphalt binder is a key material for pavement, roofing and waterproofing applications. The main use of asphalt in my country is in road construction. The most common type of flexible pavement pavement in my country is hot mix asphalt. [0004] Due to its physical properties, asphalt generally cannot be used directly and needs to be modified. Modified asphalt is the addition of external additives (modifiers) such as rubber, resin, high molecular polymer, ground rubber powder or other fillers, or taking measures such a...
