Technical Field
The invention relates to aggregate for an asphalt pavement, in particular to artificial reinforced aggregate for the asphalt pavement, which is matched with the aggregate for embedding and extruding.
Background
The asphalt pavement is a combination of asphalt and mineral aggregate through a certain physical-chemical action, and is characterized by that it possesses high asphalt content, and the contact surface between coarse aggregate is large, so that it possesses the properties of both embedded and extruded type and compact type asphalt mixture. The aggregate performance will influence the mechanical properties of asphalt pavement such as high temperature rutting resistance, low temperature cracking resistance, normal temperature fatigue resistance and the like to a great extent. The road performance of the embedded and compacted asphalt mixture depends greatly on the internal friction and the internal friction angle of the structure. The shape, surface texture, roughness and angularity of the tough particles of the stone of the coarse aggregate affect the mutual embedding and extruding and combining effect of the aggregate. The crushing value and the abrasion value of the macadam do not meet the requirements, so that the stability of the asphalt mixture is low, and the service function and the long-term service characteristic of the asphalt pavement are greatly influenced. The aggregate joint surface of the asphalt pavement is a relatively weak asphalt membrane interface formed by asphalt and stone powder, and aggregates on two sides can slide under the shearing action of the interface; this results in the asphalt pavement material having macro-plastic flowability and being prone to permanent deformation such as rutting and moving. Rutting is a macroscopic manifestation of the internal slippage of the asphalt pavement material. The internal organization structure of the asphalt concrete enables the asphalt concrete to naturally have the characteristic of easy internal slippage.

In view of the above, the present invention aims to provide an artificial reinforced aggregate for asphalt pavement, which is used for being embedded and extruded with aggregate, and can solve the problem that the asphalt pavement material is easy to slip in asphalt concrete due to permanent deformation such as rutting and moving caused by macro plastic fluidity.
The artificial asphalt pavement reinforcing aggregate used for matching with aggregate and embedding and extruding comprises a plurality of artificial particles with embedded strips, wherein the embedded strips of the artificial particles are distributed along the space and can be embedded and extruded with the aggregate to form an embedded and locked structure;
further, the artificial particle has at least three fillets;
furthermore, the embedded strips are symmetrically and fixedly connected into a whole along the center of the space;
furthermore, the embedded strips are fixedly connected into a whole along the center of the space;
further, smooth transition curved surfaces are arranged between adjacent embedded strips of the artificial particles;
further, the length of the slugs of the artificial particles is no greater than 2 cm;
furthermore, the insertion strip is of a conical structure, and the bottoms of the conical structures are symmetrically and fixedly connected into a whole along the center of the space;
furthermore, the insertion strip is of a cylindrical structure, and the bottoms of the cylindrical structures are symmetrically and fixedly connected into a whole along the center of the space;
further, the artificial particles are made of aluminum materials or steel materials.
The invention has the beneficial effects that: the artificial reinforced aggregate for asphalt pavement matched with aggregate and extruded is made of artificial particles through artificial design, the artificial particles are made of high-strength and high-ductility metal materials, and have a special structure, so that the artificial particles have high strength and good wear resistance, can bear large load without breaking and crushing, can form high internal friction resistance after being extruded with common aggregate, cannot slide the aggregate, cannot generate plastic flow tendency under the action of external horizontal load, have strong interlocking effect, and can improve the stability and the deformation resistance of an asphalt mixture.

The shape and the structure of each artificial particle 1 are consistent, and the artificial particles are manufactured by manual design, so that the uniformity of particle composition is ensured, which is completely different from the existing aggregate particles. The artificial particles 1 and the common aggregate are mutually embedded and extruded through the embedded strips 2 to form an embedded and locked structure, the structural strength is higher, higher internal friction force can be formed, slippage cannot occur between the artificial particles 1 and the aggregate, the tendency of plastic flow cannot be generated under the action of external horizontal load, the embedded and locked effect is strong, and the stability and the deformation resistance of the asphalt mixture can be improved. When the artificial particles 1 and the aggregates are mutually embedded and extruded to form a firm interlocking structure, the internal friction resistance and the bonding force are both better improved, and the asphalt mixture has better mechanical property.
