Scope

Scope: This standard specifies the terms and definitions of factory-mixed hot recycling technology, recycled asphalt pavement materials (RAP), new additive materials, the design of factory-mixed hot recycled asphalt mixtures, and the technical requirements for the construction of factory-mixed hot recycled asphalt pavements, etc. This standard applies to the construction and maintenance of factory-mixed hot recycled and warm recycled asphalt pavements on highways and urban roads of all grades using new asphalt as the base material. Main technical content: 3.1 Recycled Asphalt Pavement (RAP): Asphalt surface layer materials obtained from old asphalt pavements by milling and excavation methods. 3.2 Hot Central Plant Recycling: A recycled asphalt pavement construction technology in which asphalt mixture recycled materials (RAP) are crushed and screened in a mixing plant, and then mixed with a certain proportion of new aggregates, new asphalt, and recycling agents for paving. 3.3 Warm Central Plant Recycling: A recycled asphalt pavement construction technology in which asphalt mixture recycled materials (RAP) are crushed and screened in a mixing plant, and then mixed with a certain proportion of new aggregates, new asphalt, and warm recycling agents at a temperature 20-30°C lower than that of the corresponding hot recycled mixture for paving. 3.4 Reclaimed Asphalt in RAP: Also known as old asphalt, it refers to the aged asphalt contained in recycled asphalt pavement materials (RAP). 3.5 Rejuvenating Agent: An additive used to restore the performance of aged asphalt when added to recycled asphalt pavement materials (RAP). 3.6 Warm Mix Rejuvenating Agent: An additive used to restore the performance of aged asphalt and reduce the construction temperature by 20-30°C compared with hot recycled mixtures when added to recycled asphalt pavement materials (RAP). 3.7 Recycled Asphalt: A mixture of recycled asphalt from RAP and asphalt recycling agents and new asphalt (if necessar
