Emulsified asphalt for non-stick wheel, and preparation method thereof

Abstract

The invention relates to emulsified asphalt for a non-stick wheel, and a preparation method thereof, and belongs to the technical field of emulsified asphalt modification. The emulsified asphalt for the non-stick wheel is prepared from the following raw materials in parts by weight: 50-65 parts of petroleum asphalt, 3-8 parts of sulfur, 1-3 parts of a cationic emulsifier, 0.3-2 parts of a stabilizer, 0.5-3 parts of a pH regulator, 2-5 parts of polymer emulsion and 40-50 parts of water, wherein the petroleum asphalt comprises 10-30 parts of low-grade asphalt and 30-55 parts of high-grade asphalt. The prepared emulsified asphalt for the non-stick wheel has advantages of high demulsification speed, high film forming speed and high film forming strength, does not have the phenomenon of sticking to the tire of a construction vehicle, does not have the phenomenon of stripping of a lower layer, and has good adhesion inhibition effect on the tire; and the preparation method of the emulsified asphalt for the non-stick wheel is simple, practical and convenient to operate.

Description

technical field [0001] The invention relates to emulsified asphalt for non-stick wheels and a preparation method thereof, belonging to the technical field of emulsified asphalt modification. Background technique [0002] Before paving the asphalt mixture pavement, it is necessary to spread sticky layer oil to make the surface layers of the pavement, and between the surface layer and the structure bonded into a solid whole to form a complete force-bearing structure and reduce traffic loads. Sliding and moving between layers of the road surface or diseases such as congestion and rutting, and improve the service life of the road surface. [0003] At present, emulsified asphalt or polymer modified emulsified asphalt is often used as viscous oil in road construction. The properties of emulsified asphalt are determined by the properties of its raw material asphalt. The softening point is usually below 50°C, and the softening point is relatively low. In summer, when the sticky lay...

AI Technical Summary

Problems solved by technology

Although polymer-modified asphalt can increase the softening point of asphalt, it has the problem of high requirements for emulsification equipment, emulsification is difficult, and the production cost is relatively high

[0004] At present, the commonly used emulsified asphalt viscous layer oil has a slow demulsification speed, and it takes a long time to wait for the water to evaporate and form a film before paving the upper layer mixture, which affects the construction efficiency
