Abstract
The present invention alters a rigid layout layer of highway cement concrete into a cement concrete block surface layer in the shape of a small grid net, which is composed of cement concrete small cubic unit blocks, waterproof seam filling materials in the shape of a grid net, and crackles. The present invention converts rigid road surfaces into approximately flexible block road surfaces without pulling force, keeps that the road surfaces are smooth, without water penetration, well improves the driving comfortability on the cement concrete rigid road surfaces, and leads the 40% to 50% of thickness of the cement concrete surface layer to be reduced. Composite solidifying materials, such as NCS, etc. are adopted to stabilize fine earth, and are used as a base layer below the cement concrete surface layer in the shape of a grid net in the areas without sand or stones. The present invention is combined with the rolling technology of an impact compactor for construction, which can further save cost and improve the integral engineering quality of road beds and the road surfaces.
Description
Highway surface of concrete grids with stuffed seams belongs to novel road surface structure, is made up of cement concrete square graticule mesh joint filling surface layer, semi-rigid type base, subbase, bed course.
Cement concrete square graticule mesh joint filling surface layer is directly to bear the deck that wheel load acts on repeatedly to be influenced with natural cause, it will have cement concrete rigidity space of a whole page layer now and make the netted cement concrete square of lattice surface layer into, by cement concrete small cubes cell block, square grid shape waterproof joint sealing material and crackle are formed, traditional cement concrete rigid pavement is become cement concrete do not have pulling force square road surface, approaching flexible road surface between rigidity and flexibility, make traditional cement concrete pavement reduced thickness 40%～50% under the constant situation of supporting capacity, and improved the road-ability of cement concrete rigid surface preferably.Its key technology is to adopt the special equipment that is arranged on the sub-base grader to implement the continuous paving operation in road surface, and cement concrete pavement is divided into 15 * 15cm
2The cement concrete square of thick 10～15cm, make the wide 0.27mm of being of each side's interblock graticule mesh seam simultaneously, the interior 0.25mm of seam is wide to be the special-purpose water-proof joint sealing material, joint sealing material one side and square vertical plane secure bond, joint sealing material opposite side and square vertical plane have the wide crackle of 0.02mm, construction process requirement reaches evenness of road surface, does not seep water, and guarantee between the cement concrete square graticule mesh filler and crackle stablize indeformable, to guarantee evenness of road surface under the driving effect, comfortable.
Semi-rigid type base is arranged under the cement concrete square graticule mesh joint filling surface layer, and with surface layer subbase, bed course, soil matrix is spread in the effect repeatedly of wheel load, plays the deck of main load-bearing effect.Semi-rigid type base is except that meeting intensity index and the technical requirements by current specifications.To have a coefficient of shrinkage and drying shrinkage strain and temperature coefficient that contracts big because inorganic binder (cement, lime, flyash etc.) is stablized fine grained soils for high class pavement, easily produce serious shrinkage crack, after surface layer water infiltrates, stablizing the fine grained soils substrate surface can soften, purt mud phenomenon is washed away in generation, cause pavement destruction, thereby stipulate that basic unit can not use stable fine grained soils.Surface layer is the surface of concrete grids with stuffed seams that do not seep water now, then can adopt composite curing material settling out fine grained soilss such as NCS to do basic unit under the high class pavement, dry-shrinkage deformed little because of it, no serious shrinkage crack, no surface layer infiltration influence, for taking fine grained soils on the spot, build the road surface semi-rigid type base and started the reliable technique approach.
Subbase is arranged under the basic unit, and bears vehicular load and act on repeatedly with surface layer, basic unit, plays the deck of less important load-bearing effect.The compliant regulation is answered in the intensity index of subbase and technical requirements.
Bed course is arranged on the deck between subbase and the soil matrix, plays draining, water proof, effect such as antifreeze, antifouling, generally specifically determines according to the natural conditions of soil matrix.
Roadbed can be used impact compactor and carry out roller compaction construction except that adopting the current specifications construction, to improve the resistance to overturning and the intensity of roadbed.
Highway surface of concrete grids with stuffed seams saves 30% than current highway cement concrete pavement surface layer cost, adopt composite curing material settling out fine grained soilss such as NCS to do basic unit simultaneously in no sandstone area, then the base material expense can save 15%～20%, as rolling subgrade construction in conjunction with impact densifying-machine, also can further save cost, improve subgrade and pavement integrated engineering quality, the application of this supporting technology has huge economic and social benefits and wide application prospect.
