Abstract

The invention discloses a high-viscosity fog seal material for pre-maintenance of a drainage asphalt pavement. The high-viscosity fog seal material is composed of a component A and a component B in amass ratio of 7: 3, wherein the component A is composed of matrix asphalt and an SBS modifier in mass ratio of (60-65): (5-7), and the component B is composed of cyclohexane, kerosene, expanded vermiculite and hexadecyl trimethyl ammonium bromidein mass ratio of (2-5): 20: (2-3): (3-5). The invention also discloses a preparation method for the high-viscosity fog seal material used for pre-maintenance of the drainage asphalt pavement. The preparation method comprises the following steps: preparing the component A; preparing the component B; and slowly and uniformly mixing the component A and the component B. The high-viscosity fog seal material for the pre-maintenance of the drainage asphalt pavement has the beneficial effects that the prepared high-viscosity fog seal material can prevent and treat flying diseases without abating the skid resistance and the water permeability of the drainage asphalt pavement; operation is simple and convenient; and cost is saved.

Description

technical field [0001] The invention belongs to the research field of highway building materials, and in particular relates to a high-viscosity fog sealing layer material for drainage asphalt pavement pre-maintenance and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the traffic conditions of expressways present the characteristics of heavy load, high flow and obvious channelization, and the quality requirements for asphalt pavement are getting higher and higher. As an open-graded asphalt mixture with interconnected voids, permeable asphalt mixture has been widely used at home and abroad for its remarkable water permeability, good anti-skid performance and the function of reducing road surface temperature. At present, China has promulgated two specifications related to road performance requirements of permeable pavement, namely "Code for Design of Asphalt Pavement" (JTGD50-2006) and "Technical Specification for...
