Described level pottery cushion block and heat-transferring solution bag are one-body molded.
Described wear-resistance protective sleeve upper surface is provided with stay-warm case.
The beneficial effect of the relative prior art of the utility model:
The utility model warm-mixed asphalt concrete pavement construction transverse joint preheating apparatus, provide a kind of butt joint place old asphalt concrete to preheat, thereby it is softening that old pitch is heated up, heat newly building asphalt concrete seam basic unit simultaneously, reduce and newly mix bituminous concrete heat loss, make new, old asphalt concrete there is good cohesiveness, and then improve the construct degree of compaction at transverse joint place of new-old concrete seam, reduce attenuation of surface evenness; Avoid new and old asphalt concrete pavement damage and pollute simultaneously.
The utility model warm-mixed asphalt concrete pavement construction transverse joint preheating apparatus, simple to operate, be easy to carry, be suitable for various working environments; Bituminous concrete heating-up temperature keeps stablizing controlled; The heat-transferring solution heat time is short, and bituminous concrete softening rate is fast; Clean, road pavement and environmental nonpollution.
