Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a construction device for an emulsified asphalt sealing layer of a highway pavement structure. Background Art

[0002] Emulsified asphalt penetration layer refers to the use of emulsified asphalt to bond the pavement and base materials together to increase the waterproof performance of the pavement. The emulsified asphalt seal layer can enhance the bonding between the semi-rigid and the surface layer, making the various structural layers of the pavement an integrally stressed layered system, preventing road water from entering the semi-rigid base and causing scouring of the top surface of the semi-rigid base. The seal layer can also seal and bridge the shrinkage cracks on the surface of the semi-rigid base, inhibiting and delaying the reflection and development of cracks on the top surface of the semi-rigid base. In addition, by improving the adhesion and stability of the pavement, the emulsified asphalt seal layer greatly increases the strength performance and integrity of the pavement. It is usually constructed between the base and the road surface, with a thickness of 1-2cm. Large-area emulsified asphalt penetration layer is usually constructed by a paver. Before construction, stones are spread first, then emulsified asphalt is used to cover it, and a certain thickness of crushed stone is added. Spraying and paving are generally used. First, impurities on the road surface are cleaned, and then emulsified asphalt is sprayed on the road surface. Finally, the emulsified asphalt seal layer is evenly spread on the road surface with a paving machine. After the construction is completed, the surface layer is constructed. Traditional emulsified asphalt seal layers are mainly sprayed by spreaders on large areas, and mainly spread manually on small areas. Spreaders are used to spray on short roads, which requires large investment in equipment and high engineering costs. Manual paving requires more labor and low construction efficiency, which seriously affects the construction progress. Utility Model Content
