Description
[technical field]
The utility model belongs to technical field of engineering machinery, specifically relates to a kind of bituminous pavement vacuum road roller.
[background technology]
Bituminous pavement surfacing without seam, driving vibration is little, noise is low, open to traffic is fast, repair speed soon, is the main structure formation on China road surface. Owing to the volume of traffic is heavy gradually, vehicle-mounted load increases gradually, and the compaction quality of this road pavement is had higher requirement, although the quality of China's bituminous pavement is greatly improved, quality problems has occurred in a lot of engineering. Data shows, compacting deficiency is the one of the main reasons causing bituminous pavement quality, this is because when aggregate and pitch bond, pitch is rolled in particles of aggregates surface, block the part hole of coarse aggregate surface, the air that is in hole, water etc. stop the infiltration of pitch, and the part surface of aggregate is wrapped up by pitch not yet. When paving with compacting bituminous concrete, making particles of aggregates close to each other and extrude, the thickness of aggregate surface asphalt membrane is thinning. In the hole that the pitch extruded to be infiltrated aggregate surface and gap. Compressing the gas here, make the gaseous tension being enclosed in hole exceed barometric point, form unrelieved stress in layer, this is the intrinsic feature of common compacting. Except this kind of blind hole gap, in the boundary interacted at pitch and aggregate and pitch tissue, also there is mutually through and and the microporous network of the surperficial atmosphere of road. If the vacuum chamber having a sealing on road surface, under some microporous network is in vacuum chamber, this just destroys the force balance of the alternate instability of gas, liquid, solid body three that inside concrete interacts. The pressure of road floor air passage is just low than barometric point, and the gas in passage just moves towards the vacuum chamber that pressure is lower. Meanwhile, the pressure difference being enclosed in gas in the intrapore gaseous tension of aggregate and passage by asphalt film increases suddenly, asphalt film crack, the bubble admission passage of effusion and discharge. This contributes to pitch to be filled under the effect of surface force in the hole of aggregate and gap going, be conducive to again being uniformly distributed of pitch. In the thinning and micropore of asphalt membrane and aggregate gap, the discharge of gas, makes inside concrete stress decrease.
