Embodiment
[0038] This embodiment is a two-lane provincial road reconstruction project, the old road is a cement concrete pavement with a width of 7m, and the asphalt concrete pavement is used after the transformation.
[0039] After comprehensive treatment of the old cement pavement panel, it will be used as a cushion layer for the new pavement structure layer, and then 16-20cm6% cement stabilized graded macadam base + 18cm large particle size cement regeneration base + 8cmATB30 modified asphalt macadam underlayer + 4cm AC-13C imported asphalt concrete (diabase) upper layer.
[0040] The 18cm large particle size cement regeneration base uses large particle size gravel with a nominal particle size of 37.5 to 63 as the main aggregate; after milling the old asphalt surface layer, sieve out the milling material with a particle size of less than 16mm, and use the The old road asphalt pavement milling material with P.C32.5R cement and water is mixed in the recycling equipment to form the ceme...
