Pavement multistage rubblization construction method
The invention discloses a pavement multistage rubblization construction method. The method comprises the following steps: preparing before crushing construction; crushing the plain cement concrete panel, and integrally crushing the pavement; locally crushing local large concrete blocks on the surface of the rubblization layer; conducting breaking construction on the breaking position of the plaincement concrete slab body; backfilling graded broken stones and compacting; testing the rebound modulus of the top surface of the rubblization layer; comparing deflection average values before and after crushing; conducting crushing construction on the double-layer reinforced cement panel, and conducting punching presplitting through hydraulic punching equipment; integrally crushing the pavement;locally crushing local large concrete blocks on the surface of the rubblization layer; backfilling graded broken stones and compacting; testing the rebound modulus of the top surface of the rubblization layer; comparing deflection average values before and after crushing; and carrying out final subsequent processing. The construction process is suitable for the transformation process of most of old concrete pavements, the construction speed is high, the construction efficiency is high, important joints are subjected to strength reinforcement, and the overall construction cost is low.
