Abstract
The invention discloses processing technique dealing with asphalt pavement sink and crack, which includes following steps: drill pouring holes at cracking area piercing face and ground; pouring material into the holes and fix the ground, sealing the holes; make slots along surface gaps, fill the slots till the sinking area is flush with the ground, block the section till pulp material coagulates till the normal service will not damage the pouring pulp again. By pouring pulp material into pouring holes at sinking area, the rigidity of ground base and surface is enhanced effectively so to keep the ground from further damage, lengthening the road service life greatly.
Description
Technical field
The present invention relates to a kind of processing method that is used for bituminous pavement top-crack, depression, particularly a kind of reparation construction method that is beneficial to the reinforcement of asphalt highway basic unit.
Background technology
Diseases such as top-crack or depression often appear in flexible pavement.Rainy day, water infiltrates basic unit from pavement crack, under the driving load action, purt slurry phenomenon appears in the place, crack, and the rubble of cement stabilizing is because of water comes off, loose, road structure bearing capacity deficiency, the limit phenomenon appears gnawing, and may develop into check crack or hole groove, depression etc., and jump car when causing driving, had a strong impact on highway application life, also the safety and comfort of influence driving influence appearance of a street road looks.
The conventional method of handling asphalt pavement crack or depression disease has: 1. excavate crack or road surface, depression position, fill up again.Though this method construction simple and fast is cured the symptoms, not the disease, and causes the old complaint-water damage of damage basic unit of surface layer cracking to fail to be effectively addressed, under the load action of driving, surface layer is cracking or depression again soon; 2. in the curb position on road surface, place, crack weeper drain is set,, fills up again in conjunction with excavation location of cracks road surface.This method can effectively be dealt with problems, but have that expense height, duration are long, complex procedures,, treatment effect big to the driving influence should not control and may cause new defectives such as pavement disease.The method of handling pavement depression is to excavate to change to fill out, and the surface layer that is about to the depression position digs out, and fills again.This method is cured the symptoms, not the disease, and after a period of time was used at the position of handling well, the depression disease reappeared.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, a kind of new construction treating methods that is used for asphalt pavement crack or depression is provided, elimination causes the old complaint of crack or depression, repair top-crack or depression, the reinforcement of road pavement basic unit makes flexible pavement reach corresponding use standard.
Technical scheme of the present invention is: a kind of processing method that is used for bituminous pavement top-crack or depression is characterized in that this method may further comprise the steps: the first step, along the crack or the depression zone make grout hole, penetrate surface layer and basic unit; In second step, grout hole is in the milk levelling settlement road surface, and sealing of hole pressurize with grouting agent; The 3rd step is along top-crack or depression zone raggle; In the 4th step, be filled to equal with bituminous concrete with the road surface; In the 5th step, road closure maintenance to grouting agent coagulates together, and infringement is not as the criterion to damaging property of grouting agent with driving.
Wherein in the first step,, make single grout hole along the crack to the wall scroll crack; To the disease of check crack or depression, should be blossom type in the disease zone and lay grout hole.0.8～4.5 centimetre in described grout hole aperture, 30～200 centimetres of pitch-rows.
Pressurize described in second step extends to grouting agent and loses flowability.Described grouting agent can select the pure slurry of inorganic cement, cement mortar etc. to have the material of gelatification, and can add an amount of Admixture, or organically the pitch class and solidify after have the macromolecular material of malleable, but and admixture appropriate amount of addition agent.
Raggle described in the 3rd step for the wall scroll crack, is generally dug 1～5 centimetre of width, and the groove that the degree of depth is 3～6 centimetres for check crack or depression, should be dug out full disease zone, 6～18 centimetres of the degree of depth.
Beneficial effect of the present invention is: this method by along the crack or the depression zone make grout hole, and to this grout hole grouting, reinforcement sub-surface, subbase, effectively improve its physical and mechanical property and hydraulic performance, and then top-crack or depression zone are filled up with pitch or bituminous concrete, recover complete, the smooth-going and normal function of use in road surface, prevent that surface layer from further damaging, effectively prolong the application life on road surface.This processing method can be saved disease maintenance of surface time and maintenance costs greatly, and, eliminated old complaint, avoid the repetition maintenance, effectively reduce maintenance of surface work to the influence of traffic and the waste of fund, used slurry material is cheap, and economic benefit and social benefit are all quite remarkable.
The specific embodiment
Describe the construction embodiment that is used for bituminous pavement top-crack or depression provided by the invention now in detail:
At first, make grout hole along top-crack or depression zone, decide according to grouting agent in the aperture, 30～200 centimetres of hole array pitch, and 40～400 centimetres of hole depths will penetrate surface layer and basic unit at least.To the wall scroll crack, make single grout hole along the crack and get final product, to the disease of check crack or depression, should be blossom type and be distributed in disease zone laying grout hole.Then, an optional grout hole is installed the grouting head, and connects grout pump grouting, and grouting pressure is smaller or equal to 0.5 MPa.Grouting agent can be selected the pure slurry of inorganic cement, cement mortar and can add an amount of Admixture, or organically the pitch class and solidify after have the macromolecular material of malleable, but also admixture appropriate amount of addition agent.If grouting agent is the pure slurry of cement, the grout hole diameter is generally 3～4 centimetres; If grouting agent is a cement mortar, the grout hole diameter is generally 1.5～4.5 centimetres; If grouting agent is organic materials such as pitch class, the grout hole diameter is generally 0.8～5 centimetre.The slurry material initial set with the time generally at 30 seconds～120 minutes.When selecting inorganic material when grouting for use, when grout absorption smaller or equal to 300 ml/min, finish this grouting of this hole, when selecting organic material when grouting for use,, finish this grouting of this hole when grout absorption during smaller or equal to 10 ml/min, transfer to next hole and continue grouting, up to having irritated all grout holes.According to the depression situation above-mentioned grout hole is in the milk once more then, up to the levelling settlement road surface.Each grout hole finishes should seal pressurize immediately after the grouting, till losing flowability to grouting agent.
After pressurize finishes, wide 1～5 centimetre to the disease in wall scroll crack along crack raggle, dark 3～6 centimetres, be filled to equal then with bituminous concrete with the road surface; To the disease of check crack or depression, should chisel heavy disease zone surface layer, dark 6～18 centimetres, be padded to concordant then again with bituminous concrete with adjacent road surface.After the maintenance of closing a road to traffic was at last solidified to grouting agent, infringement was not as the criterion to damaging property of grouting agent with driving, has promptly finished the processing to the reinforcement of flexible pavement basic unit and top-crack or depression, but just open to traffic.
