Problems solved by technology

[0003] In view of this, the object of the present invention is to provide an artificial reinforced aggregate for asphalt pavement that is used to co-extrude with aggregates, which can solve the problem of permanent deformation of asphalt pavement materials such as rutting and pushing due to the large plastic fluidity on the macroscopic scale. The problem of easy slippage inside the asphalt concrete caused by

Embodiment Construction

[0017] The artificial reinforced aggregate for asphalt pavement used for coordinating with aggregates in this embodiment, the reinforced aggregate includes several artificial particles 1 with fillets 2, and the fillets 2 of the artificial particles 1 are distributed along the space and can be The interlocking structure is formed by mutual embedding and interlocking; the embedding strips 2 of the artificial particles 1 are spatially distributed, and are distributed in a three-dimensional structure in space, forming a spatial three-dimensional structure. Each artificial particle 1 has the same particle shape and structure, and is artificially designed and manufactured to ensure the uniformity of the particle composition, which is completely different from the existing aggregate particles. The interlocking structure is formed between the artificial particles 1 and the ordinary aggregate through the interlocking strip 2, which has higher structural strength and can form a higher in...

Abstract

The invention discloses an asphalt pavement artificial reinforced aggregate used for being matched and embedded with aggregate, the reinforced aggregate comprises a plurality of artificial particles with insertion strips, and the insertion strips of the artificial particles are distributed along space and can be mutually embedded and extruded with the aggregate to form an interlocking structure; the artificial particles forming the aggregate are artificially designed and manufactured, the artificial particles are made of high-strength and high-ductility metal materials, due to the specific structure, the artificial particles are high in strength, good in abrasion resistance and capable of bearing large loads without being broken and broken, the high internal friction resistance can be formed after the artificial particles and common aggregate are extruded in an embedded mode, and the aggregate cannot slide. And under the action of external horizontal load, the plastic flow trend is not generated, the interlocking effect is strong, and the stability and deformation resistance of the asphalt mixture can be improved.

Description

technical field [0001] The invention relates to an aggregate used for asphalt pavement, in particular to an artificial reinforced aggregate for asphalt pavement used for coordinating and embedding with aggregate. Background technique [0002] Asphalt pavement is a combination of asphalt and mineral aggregates through a certain physical-chemical action. It is characterized by a large amount of asphalt and a large contact surface between coarse aggregates. It has both embedded and dense asphalt mixtures. performance. Aggregate properties will largely affect the mechanical properties of asphalt pavement such as high temperature anti-rutting, low temperature cracking and normal temperature fatigue resistance. The pavement performance of embedded and dense asphalt mixtures largely depends on the internal friction resistance and internal friction angle of the structure. The toughness, particle shape, surface texture, roughness and angularity of the coarse aggregate stone all aff...
