　　The recycling application of asphalt pavement can utilize waste materials, save resources, transportation and gasoline, and protect the environment. It is an economical, green and environmentally friendly construction technology that should be vigorously promoted. The current asphalt pavement recycling technology is widely used. Below is a detailed introduction to its technical principles and construction methods.

　　There are several ways to recycle asphalt pavement materials

　　Asphalt pavement recycling technology refers to a complete set of processes in which old asphalt pavements that need to be renovated or abandoned are excavated, recycled, heated, crushed, and screened by specialized equipment for pavement recycling, and then re mixed with rejuvenators, new asphalt, new aggregates, etc. in a certain proportion to form a mixture that meets certain road performance requirements and is re paved on the pavement.

　　Asphalt pavement recycling technology can be divided into hot mixing recycling method and cold mixing recycling method according to construction temperature, and can be divided into centralized plant mixing recycling method and on-site recycling method according to different waste material mixing sites. So the asphalt pavement recycling technology can be divided into four construction methods: factory mixed hot recycling, on-site hot recycling, factory mixed cold recycling, and on-site cold recycling.

　　(1) Factory mixed hot recycling is the process of transporting waste materials from cold milling and planing of old road surfaces back to the asphalt mixing plant, and mixing them with new asphalt materials, rejuvenators, and new aggregates in a hot state according to a certain proportion to form a qualified asphalt mixture. The recycled asphalt concrete produced by the factory mixed hot recycling equipment has excellent quality and is the primary choice for road surface recycling equipment.

　　(2) In situ thermal regeneration refers to a technology that uses specialized in situ thermal regeneration equipment to heat and loosen asphalt pavement on site, adding a certain amount of new aggregate, new asphalt, rejuvenator, etc., and through mixing, paving, rolling and other processes, to achieve one-time regeneration of old asphalt concrete pavement within a certain depth range (generally not exceeding 6 cm) on the surface.

　　(3) Factory mixed cold recycling is a construction method that uses emulsified asphalt or low viscosity asphalt in a hot state to mix with waste asphalt materials and new aggregates at room temperature to form a recycled mixture. After being transported to the construction site, it is spread and compacted to form a road surface.

　　(4) On site cold recycling refers to the construction method of cold crushing and loosening old road surfaces, adding emulsified asphalt and other additives, mixing, paving, and compacting to form road surfaces.
