Abstract

The invention discloses a dust-suppression and haze-reduction asphalt modifier. The modifier is a composite material and comprises a dust-suppression component and an anti-stripping component, wherein the dust-suppression component comprises one or more of calcium chloride, ferric chloride, aluminium chloride, calcium oxalate and potassium oxalate, and the anti-stripping component comprises one or more of calcium lignosulphonate, sodium lignosulphonate and petroleum resin. The invention further discloses a preparation method of the dust-suppression and haze-reduction asphalt modifier. The method comprises steps as follows: weighing out the dust-suppression component and the anti-stripping component in a certain proportion; loading the dust-suppression component and the anti-stripping component into mixing equipment for mixing. The dust-suppression and haze-reduction asphalt modifier can be directly used as one component of a road material and is added to matrix asphalt for preparation of dust-suppression and haze-reduction asphalt, then the dust-suppression and haze-reduction asphalt is used as a cementing material for paving of a road, dust suppression and haze reduction effects are realized, and other properties of the asphalt road are not affected.

Description

technical field [0001] The invention belongs to the technical field of asphalt roads and environmental engineering, and relates to an asphalt modifier and a preparation method thereof, in particular to an asphalt modifier for dust suppression and haze reduction and a preparation method thereof. Background technique [0002] In recent years, fog and haze have occurred frequently in my country's Beijing-Tianjin-Hebei region and North China. Many cities will encounter large-scale persistent fog and haze in autumn and winter, which will seriously affect people's normal travel and daily life. The problem of air pollution has attracted widespread attention at home and abroad. Studies have shown that some harmful and toxic substances in the atmosphere can cause irreversible damage to human physiological functions and seriously affect people's physical and mental health. Therefore, it is necessary to control smog to protect the environment. imminent. In some large urban environment...
