[0043]

[0044] The preparation method of asphalt pavement heat reflective coating of the present invention, it comprises the steps:

[0045] (1), adding nano-titanium dioxide into the first water-based epoxy resin and stirring to obtain the first mixture;

[0046] (2), adding nano silicon dioxide into the first mixture and stirring to obtain the second mixture;

[0047] (3), adding iron oxide red, dispersant and matting agent into the second mixture in turn and stirring to obtain the third mixture;

[0048] (4), the second water-based epoxy resin is added to the third mixture and stirred to obtain a water-based epoxy resin coating;

[0049] (5) Brush the water-based epoxy resin paint on the surface of the asphalt pavement to obtain a coating. Within 10 minutes after the brushing is completed, spread the anti-slip agent on the surface of the coating and shape it.

Abstract

The invention discloses an asphalt pavement heat-reflecting coating and a preparation method thereof. The asphalt pavement heat-reflecting coating includes first water-borne epoxy resin, second water-borne epoxy resin, nanometer titania, nanosilicon dioxide, iron oxide red, a flatting agent, a dispersant and an anti-skid agent. Compared with traditional asphalt pavement heat-reflecting coatings, the asphalt pavement heat-reflecting coating has higher strength, adhesive capacity and durability, thus the asphalt pavement heat-reflecting coating can be applied to asphalt pavements of urban road intersections to resist the impact effect of the vehicle load, the pavement temperature in summer can be effectively lowered, track diseases are reduced, and thus the service lives of the asphalt pavements are prolonged; and by controlling the coating thicknesses with different asphalt pavement gradation types to reduce decreasement of the coating on an original pavement pore structure, meanwhile,a microcosmic anti-skid structure is provided by spreading the anti-skid agent, the anti-skid performance is good, and thus the traffic safety is ensured.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to an asphalt pavement heat reflective coating and a preparation method thereof, and more particularly relates to an asphalt pavement solar heat reflective coating used at urban road intersections and a preparation method thereof. Background technique [0002] Rutting, moving, and wrapping are typical diseases of asphalt pavement in the intersection area, and the root cause is that the shear strength of asphalt concrete cannot adapt to the special working conditions of the asphalt pavement in the intersection area. In the intersection area, the vehicle behavior and road load characteristics are significantly different from the general road surface: heavily channelized traffic, frequent braking and starting, slow vehicle speed, and long parking time. This special working condition makes the asphalt pavement in the intersection area bear extremely heavy traffic lo...
