Technical field
The present invention usually relates to method and synthetics, and it can improve the intensity and the life-span of Class II highway through the way of enabling environment; Be particularly related to and improve dust inhibition, soil stability and repellency.
Background technology
Class II highway (is after this claimed " macadam "; " muddy and ruthed lane " or " not laying the road ") design and build the puzzlement always receive two interrelated problems: because the road that water causes damages, and the cohesion on the surface of causing because of the traffic reason and the loss of road compactness.Especially water has had detailed description to harmful effect of highway in technology before.In cold climates, the moisture of infiltration roadbed is freezed and is pulled slight crack at the roadbed bottom, the carrying capacity of havoc road and life-span.Equally, under the weather of gentleness, cause softening and erosion when water infiltrates roadbed, formed pothole is a costliness and problem repeatedly.If pothole is not repaired immediately, will ponding and further aggravate the damage of highway.
Water is to Class II highway (country road for example; Branch road, field and woods road, or hill path) influence proposed by special; Be because the mass ratio of its ground surface material uses the road quality of laying such as petrolize low, thereby the protection road surface does not receive the ability of these factor affecting lower yet.In addition, because capillary action, water also can be from the side and bottom or road base infiltration roadbed of roadbed.With rely on big machinery pour into concrete or laying and through grating be that the sealing on basis or the road of " layings " are compared with pitch, secondary not the construction on causeway road relatively easy with cheaply.But the causeway road does not need more frequent safeguarding (especially meet the water phase or run under the situation that the volume of traffic increases), and the general easy impossible problem of laying road that runs into other.
For example, what many Class II highways (earth or granular-type road) used is local soil, also uses the rubble of local exploitation usually together, sets up the stratum basale and the base course of road.But it's a pity that local soil and rubble quality often are not the most suitable, cause the physics of roadbed and the reduction of mechanical attributes.Build when Class II highway uses relatively poor roadbed material, conventional maintenance can not strictly be carried out, and road is in again under the situation of the high humidity and/or the high volume of traffic, because to road surface, and the damage of stratum basale and roadbed material, and accelerated the erosion of road.
The defective of pavement of road often is divided into two big types: road wear and surface deformation.Road wear mainly is relevant to the reactive mode of weather or traffic pressure with the quality and the material of ground surface material; And surface deformation is usually because some composite factor, and it comprises the pressure that bears on road surface itself and such as others such as the supporting capacity of stratum basale and roadbed and stability.
Road wear can " dust " be an example, is the result of the meticulous bond material loss in road surface.Dust is a significant problem of Class II highway, damages the for example loss of the cohesion of road packing material and compactness, and the reduction that in road is filled, keeps the ability of necessary humidity owing to these fine materials of loss cause the road of other type.
Surface deformation comprises rut, wrinkle, depression and pit.Rut is because of humidity is high, and surface soil or subgrade strength is not enough, skin depth is not enough or heavy traffic load and the vertical depression on wheel trajectories that causes down.Wrinkle or " washing board " are to cause a series of protuberance in road surface and depression because the road surface cohesion is not enough.Depression is because sedimentation, humidity are excessive, with and/or unsuitable draining and cause local than around the road surface hang down one inch or more.Pit is some inch or darker little depression or the hole that forms on the road surface, is because humidity is excessive, impeded drainage, roadbed bottom or roadbed is insecure, the grating pellet is not good, or the mixing of above-mentioned these factors.
Therefore; These problems of road wear and distortion are relevant with Class II highway usually; The reason of its formation is: the 1) harmful effect of water and high humidity; Comprising the sedimentation and the erosion of road surface and roadbed, 2) cohesion that causes owing to dust lacks and the loss of road compactness, and 3) road with insecure or insufficient soil, stratum basale or roadbed carries the heavy traffic load.
The method that has proposed to add the different chemical additive in the industry increases the repellency of pavement material, and its effect and environmental influence are had nothing in common with each other.But the repellency chemical material is not a ramming material, and makes an addition to carrying capacity and the stability of not improving road behind soil or the roadbed.Under a lot of situation, applied chemistry is added composition and can be reduced dust (being commonly called the technology of " dust-inhibitor " or " dust-proofing agent ") on macadam, improves the cohesion of fine aggregate through the mode that from air, absorbs moisture." soil stabilizer " is a kind of being used for as the chemical substance that ramming material makes soil or the binding key between particulate of gathering materials combines in addition, and it provides sound assurance to improving road load supporting capacity and traffic capacity greatly.But existing soil stabilizer and dust-proofing agent are difficult to use at the weather of cold, often set time long, life cycle is short, and necessary protection can't be provided to the destruction of water; Especially true on the excessive capillary problem that causes of humidity.
Therefore; A kind of single synthetics of having the ability to address the above problem---it can provide repellency to reduce humidity; Provide dust reduction capability with raising road surface force of cohesion, and provide soil stabilizer to improve load carrying power and traffic capacity---will great purposes be arranged in technical field; It is especially true when if this synthetics can be used with the mode of economy and environmental protection.Although Road construction person adopts soil additive as a kind of approach that prevents road wear and distortion for a long time; But make a kind of prescription of synthetics, and with have cost-benefit mode use the method for this chemicaladditives be proved to be all the time the difficulty.Particularly; Although provide various chemical materials in order to combine roadbed material; To gain in strength and load bearing capacity; And road surface scold water, but the solution that these effort so far all do not have to provide a kind of Class II highway of environmental protection to corrode and safeguard, this problem has become the long-term puzzlement of this technology.Therefore, the synthetics of a kind of improvement of this Technology Need can provide the load bearing capacity of special reinforcement, and outstanding dirt exclusion capabilities outstanding is scolded the water characteristic, and can implement with independent applying step.This improvement synthetics can cover for muddy and ruthed lane or macadam provide the repellency roadbed of an engineering stability and road surface; Perhaps, can these use road base of preparation or roadbed for crushed stone sealing, laying or milling.
Damaging road with the traditional method reparation maybe be very expensive, consuming time, and destroys environment, because the metalling of the whole compacting of road all will be changed again.Dig out the roadbed of one section 1 kilometer long 4 meters broad way section, can produce the native stone rubbish of 2000 cubic metres (m3); In a traditional roadbed items of repair job, this will clear up the inferior rubbish of about 220 trucies and go out the construction site, and have the inferior new rubble of 220 trucies to be transported to the working-yard to accomplish whole project in addition.In remote place; Or the place of landform difficulty; The expense of cleaning and replacement rubble is very expensive---to local resident's influence very big (they will stand construction noise and atmospheric pollution) too; The affected common user (during repairing, will detour or stand delay) who also has highway, and the refuse landfill of depositing and removing construction rubbish.
Therefore, this Technology Need one single step chemical treatment method, but its chemical substance that can in local soil, mix stable soil, dust suppression and scold water.Handle through this single step, Road construction person can improve the life-span of road, increase load carrying power and traffic capacity, and reduce the time, expenditure and the environmental influence that come with traditional road maintenance project.
Summary of the invention
In view of the above, the object of the invention and advantage are to provide a kind of single synthetics improving soil or roadbed material, and it can make local soil or other roadbed material have very outstanding dust control, soil stabilization and scold the characteristic of water.
In addition, the invention provides a kind of method, be used for single step and handle soil or roadbed material; It can reduce set time; Reducing the constructing road time, reduce the influence (through reducing building waste and traffic) to environment, is that road has wider effective use temperature; Longer life cycle, and more firmly more dust suppression.
For the people who is familiar with present technique, through reading and understanding following embodiment, other benefit and advantage will be conspicuous.
