Description

Technical field

[0001] The invention relates to a roller compacted asphalt concrete paving and construction machine for an anti-seepage core wall of an earth-rock dam, in particular to a hydraulic roller compacted asphalt concrete core wall crawler type combined paver. Background technique

[0002] The core wall roller compacted asphalt concrete paving machine is the key machine for the construction of the roller compacted asphalt concrete anti-seepage core wall of the hydraulic earth-rock dam. The paving construction of the domestic hydraulic earth-rock dam core wall roller compacted asphalt concrete and transition material relies on imports. Equipment solution, only a few large companies abroad can manufacture roller compacted asphalt paver for hydraulic earth-rock dam impervious core wall. The price and maintenance cost are high, which increases the engineering cost of the construction unit. Moreover, the maximum thickness of the asphalt mixture paving machine for the anti-see...
