Abstract

The invention relates to bituminous mixture laying equipment capable of protecting a bonding layer, which comprises a bituminous mixture receiving hopper, a power system, a control station, a bituminous mixture distributor, a traveling mechanism, a bituminous mixture conveyor, a bonding layer material storage tank, an ironing device, a bonding layer material spraying mechanism, a bonding layer material pumping mechanism and a heater, wherein a heat conducting oil pipeline is connected with the heater; the bonding layer material storage tank is connected with the bonding layer material pumpingmechanism which is also connected with the bonding layer material spraying mechanism; the bonding layer material spraying mechanism is positioned below a machine frame and in front of the bituminous mixture distributor; and the ironing device is arranged at the rear end of the machine frame and positioned behind the bituminous mixture distributor. Seamless transition between bonding layer material spraying and bituminous mixture laying is realized through the combination of the laying equipment and automatic bonding layer spraying equipment, so the damage and the pollution to the bonding layer in a construction process are avoided and the construction period is shortened.

Description

technical field

[0001] The present invention relates to a construction equipment and application method, in particular to an asphalt mixture paving equipment and application method capable of protecting the bonding layer, the equipment and application method can be applied to bridge decks, tunnels or pavement Paving of binder courses and asphalt mixtures. Background technique

[0002] The lower sealing layer and adhesive layer of highway asphalt pavement, and the waterproof adhesive layer of bridge deck pavement are important components in the structure of asphalt pavement. They play an important role in ensuring the integrity of the asphalt pavement structure, making the asphalt pavement layers coordinate with each other, and avoiding early damage to the pavement structure due to stress concentration under the action of vehicle loads. In addition, the lower sealing layer and the bonding layer can also act as a sealing structure layer, preventing surface water from entering...
