Compared with ordinary hot mix asphalt mixture construction equipment, the mixing equipment for plant mixed hot recycled asphalt mixture is basically the same, except for some parts that are different from the mixing equipment for hot mix asphalt mixture.
Plant mixed hot recycled asphalt mixture is a hot mixed asphalt mixture that meets the requirements of new asphalt mixture grading, the amount of regenerant, and the amount of new material added based on the asphalt content and performance of the waste asphalt mixture and its mineral aggregate grading ratio determined through experiments. Therefore, the recycled asphalt mixture has good technical performance.
Due to the addition of new asphalt and aggregates, the gradation and performance requirements of the asphalt mixture have been met. The asphalt mixture pavement formed by spreading and rolling the plant mixed hot recycled asphalt mixture is basically the same as the new asphalt mixture pavement, which can better restore the bearing capacity of the pavement. Its construction quality standards will not be reduced due to the use of waste and old mixtures.
The performance of the asphalt mixture after plant mixed hot recycling can be designed according to the application engineering conditions of the recycled material to meet the corresponding engineering requirements. Generally, it can be used for the asphalt surface layer, lower layer, or flexible base layer of various levels of highways.
The construction of factory mixed hot recycled asphalt mixture pavement is a process of milling and crushing waste asphalt pavement materials, adding regenerants and new aggregates, heating and mixing them in the factory mixing equipment to restore their road performance, and then re laying them into asphalt pavement.
