Problems solved by technology

[0004] Most of the existing colored asphalt binders are in liquid state, and special vehicles are required to transport liquid asphalt, and liquid high-temperature transportation is very dangerous and troublesome
And the engineering quantity of colored asphalt pavement is generally small, the project is scattered, and the cost of special transport vehicles is high. The use of liquid colored asphalt requires special asphalt tanks. After passing through various asphalt pipelines, valves and other paths, due to the small amount of use, frequent and troublesome cleaning

preparation example Construction

[0024] The present invention also provides a preparation method of the above-mentioned granular colored asphalt, which includes adding C5 petroleum resin, C9 petroleum resin, SBS, and polyurethane into a high-speed mixer and stirring for 5 minutes, and then adding aromatic oil and stirring for 10 minutes to make the aromatic oil front The added materials are fully absorbed, and finally polyethylene wax, phosphate ester, SBR, and pigments are added, and stirred for 10 minutes, so that the powdery materials such as pigments are adsorbed on the surface of the granular materials, and mixed evenly; the mixed materials are added to the twin-screw extrusion In the feeding hopper of the machine, the temperature of each section of the screw is set to 140℃~170℃, and the granular colored asphalt can be obtained through the processes of extrusion, drawing, cooling, pelletizing, and drying.

[0025] In specific embodiments, the method for producing colored asphalt mixture using the granular co...

Embodiment 1

[0032] Take 10 parts of C5 petroleum resin, 40 parts of C9 petroleum resin, 50 parts of aromatic oil, 12 parts of SBS, 2 parts of polyethylene wax, 4 parts of SBR, 5 parts of polyurethane, 40 parts of iron red, and 3 parts of phosphate. Add the above-mentioned C5 petroleum resin, C9 petroleum resin, SBS, and polyurethane into a high-speed mixer and stir for 5 minutes, then add aromatic oil and stir for 10 minutes to fully absorb the materials added in front of the aromatic oil, and finally add polyethylene wax, Phosphate, SBR, iron red, stir for 10 minutes, so that the powdery materials such as pigments are adsorbed on the surface of the granular materials, and the mixture is evenly mixed.

[0033] Add the uniformly mixed materials into the feed hopper of the twin-screw extruder. The temperature of the screw is set to 140°C, 145°C, 150°C, 155°C, 160°C, 160°C, and 155°C from the feeding section to the die head. Extrusion, drawing, cooling, pelletizing, drying and other processes c...

Embodiment 2

[0036] Take 15 parts of C5 petroleum resin, 35 parts of C9 petroleum resin, 55 parts of aromatic oil, 15 parts of SBS, 4 parts of polyethylene wax, 5 parts of SBR, 4 parts of polyurethane, 45 parts of chrome green, and 4 parts of phosphate. Add the above-mentioned C5 petroleum resin, C9 petroleum resin, SBS, and polyurethane into a high-speed mixer and stir for 5 minutes, then add aromatic oil and stir for 10 minutes to fully absorb the materials added in front of the aromatic oil, and finally add polyethylene wax, Phosphate, SBR, chrome green, stir for 10 minutes, so that the powdery materials such as pigments are absorbed on the surface of the granular materials, and the mixture is evenly mixed.

[0037] Add the uniformly mixed materials into the feed hopper of the twin-screw extruder. The temperature of the screw is set to 150°C, 155°C, 160°C, 165°C, 170°C, 165°C, and 155°C from the feeding section to the die head. Extrusion, stranding, cooling, pelletizing, drying and other p...

Abstract

The invention relates to the technical field of road engineering, and particularly discloses granular colored asphalt and a preparation method thereof. The colored asphalt comprises the following rawmaterial components in parts by mass: 5-20 parts of C5 petroleum resin, 20-50 parts of C9 petroleum resin, 30-70 parts of aromatic oil, 5-20 parts of styrene-butadiene-styrene block copolymer, 1-5 parts of polyethylene wax, 1-5 parts of styrene-butadiene rubber, 2-8 parts of polyurethane, 30-50 parts of pigment and 1-5 parts of phosphate ester. The colored asphalt provided by the invention is granular, is convenient to transport and use, can be directly added into a mixing cylinder, and is dispersed in a colored asphalt mixture by a shearing action of hot aggregate; and the colored asphalt hasgood adhesion, good high-temperature performance, low-temperature performance and water loss resistance, and can be especially used in occasions such as a high-temperature, large-traffic-volume or water-permeable pavement in the south.

Description

Technical field [0001] The invention relates to the technical field of road engineering, in particular to a granular colored asphalt and a preparation method thereof. Background technique [0002] The colored asphalt pavement improves the black monotony of the ordinary asphalt pavement, and can be matched and coordinated with the surrounding buildings and landscape, and has obvious landscape benefits. In addition, people pay more and more attention to the organization and management of colored asphalt pavement in traffic, and play a role in inducing traffic flow, driving safely, and visualizing traffic management. Colored asphalt pavements are widely used in bus lanes, bicycle lanes, crossroads, zebra crossings, park roads, community roads, squares, sports facilities, etc. [0003] Colored asphalt pavement mainly refers to the asphalt concrete pavement with added pigments, the use of petroleum resin (light-colored asphalt) and the asphalt pavement with pigments added to the mixtur...
