As another improvement project of the present invention be: described cement modifier is an acrylic compounds--the polyocarboxy acid type cement modifier.
The particle diameter rubble that waits that the present invention is used can be hard rubbles such as limestone, granite, basalt, andesite, acrylic compounds-polyocarboxy acid type cement modifier can buy from the market, also can adopt similar cement modifier, the used waterproof roll of the present invention is general waterproof roll, as rubber water-proofing coiled, vinyl polymer waterproof roll etc.
Technical indicator: make test block with conventional method, its compressive strength is: 2Mpa-35Mpa, rupture strength 1Mpa-6Mpa, porosity 5-30%.
Road structure: according to different vehicle flowrates and road quality classification, the basic unit of porous portland cement concrete can adopt rendzinas, two-ash soil, two-ash broken stones, cement stabilized macadam etc.The porous portland cement concrete is as the following surface layer on road surface, the water coiled material of setting up defences below this layer, the asphalt concrete of making 10mm-40mm or modified bitumen concrete or color elastic road surface in the above, or many broken-stone layer pitchings.
Job practices: the basic unit's top layer laying water-proof coiled material below the porous portland cement concrete at first, spray heated bitumen in the basic unit, follow the laying coiled material closely, most of coiled material and following basic unit are linked together.Above direct making porous portland cement concrete.
The employing asphalt remixer paves.Dump truck is poured the porous modified cement concrete mixed material that mixes in the hopper of paver voluntarily, and by paver leveling voluntarily, vibrate, vibrate, ram by force, pave, i.e. moulding need not to roll again.
After the moulding of porous portland cement concrete making, should in time cover health.Available geotextiles, hydroscopic substances such as the piece of sack cover health.Can remove the health overburden after 4 days.
After reaching intensity, the porous portland cement concrete can carry out the making on road surface.
Progress of the present invention is embodied in:
1, laying water-proof coiled material on sub-surface does not have in prior art.Effectively anti-sealing is penetrated in the basic unit, and all moisture content can be discharged to the roadbed both sides by the hole of porous portland cement concrete.2, the fine aggregate beyond the porous portland cement concrete of the present invention, cement-free, not hydrophilic, do not produce frost heave like this, under the vehicular load effect, do not produce fragmentation, prolong road life, in existing technology, do not have.3, the present invention adopts the asphalt paver moulding, need not roll, in paving, utilize the vibration compacting function of ironing plate of asphalt spreader, make the skeleton in the concrete form good stone-stone contact structures, the cement paste on the contact surface plays good cementation, forms the needed enough intensity of road, so no longer need to roll, this does not have in the middle of prior art.4 because macrovoid is not established the shrinkage joint, anti-low-temperature cracking, and high-temperature stable does not have in existing cement concrete.5 because the characteristics of this structure, Deng the formation of particle diameter rubble is stone-stone contact structures, do not exist fines to fill the situation in skeleton space, so form great matsurface, matsurface can combine well with upper layer greatly, and because the greatly and equably concavo-convex lateral pressure that is handed down by wearing layer (upper layer) that is highly resistant to effectively prevents the upper layer lateral displacement, wearing layer is a thin layer in addition, thereby improves the ability of anti-rut.6, the present invention does not establish road kerb, can be shaped to the lateral surface of different shape in paving in the edge, is equivalent to existing sand concrete free road kerb.Can effectively play sound deadening.The sound that causes of driving passes in the porous portland cement concrete layer by road surface as thin as a wafer, by long slowly pore channel, lingering sound from the dual-side of porous modification concrete along discharge.7, owing to added cement modifier, cement concrete has been carried out modification, compressive strength of the present invention reaches more than the 20Mpa, and rupture strength reaches more than the 3Mpa, and this does not have in the macrovoid cement concrete.8, this porous portland cement concrete also can be used for basic unit, the surface layer of highway upper layer, square, pedestrian street, urban road, construction is fast simple, but the full mechanization construction can be seeped water fast, also can be made into porous colour modification concrete road surface, attractive in appearance, practical, suction noise.
