Description
Technical field
The present invention relates to a kind of road structure and job practices thereof, especially a kind of waterproof shock-absorption road surface structure and job practices thereof.
Background technology
In fields such as road, airfield runway and urban operating mechanisms, pavement life shortens a great problem that has become in the construction.Cause the reason of road surface early damage, the lost of life to have many.Wherein, studies show that " water is the dead enemy ".According to the source of water, the road surface damage by water is bad can be divided into two kinds of the bad and underground water damages of road table damage by water.
Road table damage by water is bad, mainly be show the way the table water (as rainwater) enter surface layer inside by surface layer hole, seam or crack, cause the surface material damage by water bad, water further infiltrates basic unit, cause basic unit to move the water erosion damage, and between surface layer and basic unit, form non-homogeneous coming to nothing and non-homogeneous supporting, for asphalt concrete pavement, the moving water of interlayer washes away the adhesion stress that also can weaken surface layer and basic unit, is unfavorable for that asphalt concrete pavement is stressed.When water further infilters into roadbed down again, if subgrade drainage is bad then to make it be immersed in water for a long time, roadbed material intensity and bullet mould reduce, and easily cause the roadbed unstability, then cause basic unit's depression, fracture, cause surface layer purt mud phenomenon, depression and rupture failure to occur at last.Solve road table damage by water bad aspect, existing road surface has the measure that porous draining basic unit is set between surface layer and basic unit, the road table water that infiltrates basic unit is discharged beyond the road surface, has obtained certain effect.
Underground water damages, and is meant big roadbed soil of humidity or the higher area of groundwater table, and the water in roadbed soil, roadbed bottom or the cut slope enters the pavement destruction that road structure inside causes by capillarity or side direction seepage flow.Underground water corrodes basic unit for a long time, weakens the bulk strength of subbase, basic unit, reduces the bullet mould of base material, and influence of dynamic water also can quicken basic unit's destruction simultaneously, thereby causes top course depression, rupture failure.In addition, when underground water enters road structure inside, under the continuous extruding of carload especially heavy duty, also can attach a small amount of roadbed fine grained soils, cause the roadbed fine grained soils to run off, the roadbed bulk strength reduces and influences the road structure bearing capacity, and the roadbed fine grained soils also can cause the road surface purt mud phenomenon frequently to occur with the subsidiary rising of water, the fine grained soils that rises also can stop up the drainage blanket passage, causes impeded drainage.In addition, at northern extremely frigid zones, underground water also can cause the frost heaving failure of roadbed, has aggravated the reduction of service life of road surface.Exist countless capillary tubies in the subgrade soils, underground water can rise to roadbed inside by the capillary tube in the roadbed, especially in the winter time, and when the atmosphere subzero temperature imports into underground, Free water in the face of land is the glaciation crystal at first, along with the continuation decline of temperature, the outermost layer of water of hydration also begins to freeze, and ice crystal is enlarged gradually, and in soil layer, form ice band, the freezing back of moisture volume will increase, and the soil body is swelled along with expanding, and frost heaving occur.Particulate is many more in soil, and the capillary tube of formation is just many more, and is also big more to the frost heave influence of roadbed.Therefore must effectively stop the structural damage of underground water road pavement.
The existing measure that stops underground water to enter ground mainly contains: the first, drainage blankets such as gravel, honeycombed cement stabilization gravel are set, and this measure can reduce capillary tube, controls phreatic rising quantity.But still have part water to continue to rise to road structure inside by capillarity.Simultaneously, in the higher highway section of groundwater table, because roadbed is in dampness for a long time, the continuous vibration effect of traffic load will make that the roadbed soil property is softening, soil particle attenuates, and the subsidiary roadbed fine grained soils of underground infiltration rises under load vibration extruding.The roadbed fine grained soils rises to bed course and brings two adverse consequences: the one, and the roadbed fine grained soils runs off, and causes subgrade soils intensity to reduce, and causes pavement depression and destroys; The 2nd, the roadbed fine grained soils rises and fills the hole of drainage blanket, easily causes bedding course drainage not smooth, and owing to the bed course porosity diminishes, capillary tube attenuates, it is big that rise waterborne becomes, and strengthened the capillarity of water, and underground water is easier to rise to basic unit even surface layer by capillarity.Basic unit on the bed course all is stabilized with inorganic binder pellet semi-rigid type base basically, himself be difficult to stop fully the infiltration of water, and drying shrinkage and warm draw line ubiquity, these are carried secretly by capillarity to underground water undoubtedly, and the roadbed fine grained soils rises to basic unit together and surface layer provides passage, causes basic unit, surface layer damage by water evil idea and mud pumping phenomenon thus.Simultaneously, the construction quality of honeycombed cement stabilization gravel class drainage blanket requires high, and the system of mixing of drainage blanket compound is high especially to the requirement of water supply volume, and is if water supply volume is too small, loose easily when rolling compound; If water supply volume is excessive, segregation phenomenon then appears easily, and construction control is bad, will influence its drainage effect, and porosity reduces provides capillary channel.The second, in the winter of northern extremely frigid zones,, adopt usually and change the way of banketing for solving the roadbed frost heaving failure, promptly water good stability, non-heaving soil or weak swelling soil change the top of filling out roadbed, as sand, gravel, slag etc.Adopt this measure can alleviate the frost heave degree of roadbed greatly, but the problem that exists is that because the rising of capillary water, underground water still can cause the frost heaving failure of road structure inside.Even drainage blanket is set again, capillary water also can infiltrate in the bed course and congeal into ice, and causes the bed course frost heaving.Bed course generation frost-heaving deformation, basic unit be must be subjected to and its vertical direction and the tangential constraint of interlayer given, this constraint is strong more, the restraint forces that bed course is subjected to is just big more, correspondingly, the reaction force that bed course gives basic unit is also just big more, and this reaction force comprises extruding force and interlayer tangential shearing or the frictional force (to basic unit, this shearing or frictional force performance be basic unit bottom tension) of bed course for basic unit.Semi-rigid sub-base material has high compression strength, can resist the compressive stress that extruding force produces, but, the tensile strength of semi-rigid sub-base material is less, the interlayer tangential force makes basic unit's tension, and then can cause adverse effect to basic unit, even when this tensile stress reaches its tensile strength, base course crack occurs, cause pavement destruction.In addition, for the rigid pavement structure, when for example being cement concrete pavement, because cement concrete material fragility is bigger, the surface layer rigidity is big, there be non-homogeneous coming to nothing and non-homogeneous supporting in interlayer when contacting with basic unit, under the vibratory impulse effect of heavy load, surface layer is stressed unfavorable, and reduce fatigue life, when especially basic unit is semi-rigid type base or rigid base, surface layer and basic unit are very stiff and demanding, and the low-cycle fatigue failure under the high stress level takes place down easily for surface material and base material antivibration scarce capacity, heavily loaded vibratory impulse, pavement destruction, and then infiltrate basic unit and roadbed provides passage for road table water.
Therefore need a kind of waterproof that has, the road structure and the job practices thereof that have vibration-damping function simultaneously, can effectively stop from bottom to top underground water and top-down road to show the destruction that water road pavement structure causes, and can also improve surface layer support conditions, enhancing surface layer antivibration ability, prolong service life of road surface.
