Key Technology of Asphalt Pavement Hot-In-Place Recycling

The hot-in-place recycling technology of asphalt pavement has been one of the main methods for asphalt pavement reconstruction. Taken the hot-in-place recycling technology as the research object,the article studies the key technologies such as the survey and evaluation of the original road, asphalt recovery and regeneration agent selection, the old and new asphalt mixing performance test, Marshall asphalt mixture design, and so on. Combined with laboratory tests and practical projects,the results can guide the hot-in-place recycling technology application of asphalt pavement effectively.
