Description
Technical field
The present invention relates to road-making material and constructional method thereof, specifically is a kind of road-making material and constructional method thereof with the building castoff preparation.
Background technology
The waste that building castoff is produced when being meant construction, repairerment and demolition of buildings has useless tile block, barren rock material, concrete blocks, sand-lime soil usually.Along with the development quickening of urbanization process of China's modernization construction, large-scale new town construction and reconstruction of the old city town cause the increasing of building castoff.Building castoff is the chief component of municipal wastes, accounts for the 30-40% of municipal wastes total amount.Overwhelming majority building castoff all is unprocessed direct stacking or landfill, has not only taken a large amount of soils, contaminate environment, and has caused a large amount of wastes of resource.Because China built in the last few years on a large scale, had expended material of construction such as a large amount of sand, stone and cement always.Natural resource such as a large amount of exploitation sand, stone cause the resource anxiety, environmental degradation.People inquire into building castoff are utilized again, mainly are to be prepared as regeneration aggregate or building slab.Because the physicals of building castoff and natural building material has than big-difference, bigger as the building castoff water-intake rate, be generally 3.6～8%, and the water-intake rate of natural aggregate can not guarantee the work-ing life of construction quality and road less than 3% as adopting usual method.
Summary of the invention
The purpose of this invention is to provide a kind of regenerative road material and constructional method thereof with the building castoff preparation.The present invention uses the cement stabilizing building castoff, makes building castoff become course as town road trunk roads, secondary distributor road, branch road and construction road.

Embodiment
1,, removes wherein metal, timber and impurity to the building castoff sorting.
2, the fragmentation of building castoff is taked to concentrate broken principle in the engineering, can adopt one-level fragmentation or two-stage crushing as the case may be.By the level screening, get extraordinarily thick aggregate, coarse aggregate, middle coarse aggregate, fine aggregate, fine, in the aggregate, useless brick: waste and old concrete is about 3: 1; Aggregate: fine is about 6: 4, and water content is less than 5%.
Particulate component and the particle diameter requirement after fragmentation, screening of building castoff and soil
Shaping test piece; Maximum dry density and optimum moisture content: determine by modified compaction test.
3, get the raw materials ready,
According to the design needs is that the course of town road trunk roads, secondary distributor road, branch road and construction road is equipped with extraordinarily thick aggregate, coarse aggregate, middle coarse aggregate, and fine aggregate and fine are dried gathering materials.Press cement dosage=cement quality/(cement quality+dried aggregate quality) and be equipped with cement, cement consumption is generally 4.0～6.0%, permissible error is+0.5～+ 1.0%, when cement stabilizing building castoff mechanical property can not satisfy requiring of upward showing, the testing data that cement dosage Ying Yineng meets the demands was as the criterion.Usually select 32.5,42.5,52.5,62.5 grades of ordinary Portland cements, Portland blast and Portland pozzolana cements meeting national standard for use, require presetting period 〉=3 hour of cement, the cement of final setting time 〉=6 hour should not use rapid hardening cement, short-term strength cement and in wet condition rotten cement.。

| Proportion (%) | 10～30 | 10～25 | 25～50 |
Road course typical composition proportioning table
Per-cent is mass percent in the table
4, by design requirements batching each raw material being added cement and water stirs and is cement stabilizing building castoff regenerative road material.
5, the constructional method for preparing regenerative road material with building castoff,
(1) mixes and stirs
Take the mode of central mix, i.e. plantmix's mode of mechanize, also mode is mixed as a supplement in the field of available shovel loader in case of necessity.Require cement and regeneration aggregate uniform mixing, do not have obviously segregation.Water content according to regeneration aggregate and brick is determined amount of water, and general amount of water needs greater than optimum moisture content 1～2%.
(2) road construction
Cement with 4～6% is transported to the working-yard after adding the water uniform mixing with the regeneration aggregate of setting grating, bed course surfacing absolute altitude with setting is a basic point, coefficient of loose laying with setting is a foundation, auxilliary by predetermined absolute altitude with the excavator stand, with spirit-leveling instrument tracking measurement absolute altitude, determine manually to shakeout behind the absolute altitude in the paving process by absolute altitude.
Whenever the 2m that paves in the paving process measures one group of absolute altitude, center line a bit, center line to the sideline by each side of horizontal wall inscription requirement of 2% some, the each point absolute altitude is determined to reach after the requirement, sprinkles lime as mark, serves as according to manually paving with the lime point again.18t vibroll static pressure twice is used in pave smooth back, speed 1.5km/h, and tracking measurement absolute altitude behind each static pressure manually shakeouts by absolute altitude.Shake after static pressure finishes again and press twice, speed 1.5km/h shakes at every turn and presses back tracking measurement absolute altitude, manually shakeouts by absolute altitude, and static pressure is one time then, speed 3km/h.Check absolute altitude after having pressed.Measure compacted depth, determine or the adjustment coefficient of loose laying.Bed course making construction quality should reach the requirement of relevant criterion.Making cement stabilizing regeneration aggregate will have been controlled material well from the time that blunge finishes to paving, and the making time should be in 3 hours.
According to have a lot of social connections, that the wheel of street roller is wide with wheelspan is different, works out and rolls scheme, the number of times that each several part is rolled is identical as far as possible, multiple pressure is answered 2～3 times in the both sides on road surface.Forbid street roller tune or bring to a halt on completed or the highway section of rolling, should guarantee that the stabilizing layer surface is not damaged.Roll in the process, the surface of cement stabilizing building castoff should remain moistening, and is too fast as moisture evaporation, should in time mend and spread a spot of water, presses but forbid to spill a large amount of water-powered rollers.Roll in the process as phenomenons such as " spring ", loose, peeling occur, should in time open and mix and stir again, can add an amount of cement or handle, make it reach specification of quality with additive method.The processing of seam and switch area is by the construction of corresponding road surface construction technique normalizing.
The cement stabilizing building castoff is as the road course when constructing, and sub-layer rolls to be finished and health making upper strata cement stabilizing building castoff after 7 days.Before the cement stabilizing building castoff of making upper strata, should remain lower floor's surface wettability.Each section rolls to be finished and after the compactness passed examination, should begin health immediately.The health way can be carried out by corresponding standard.The preserving period of cement stabilizing layer should not be less than 7 days.Between preserving period, do not adopt the cement stabilizing building castoff of covering measure, except that the water barrow, answer close traffic.On the cement stabilizing layer that adopts the covering measure, in the time of can not close traffic, it be current to limit loaded vehicle, and the speed of a motor vehicle of other vehicles should not surpass 30km/h.
Check prepares the compactness and the mechanical property of regenerative road material with building castoff
The compactness of cement stabilizing building castoff and mechanical property
| Level | Cement mixing content (%) | Compactness (%) | 7d unconfined compression strength (MPa) |
| Bed course | 4～6％ | ≥96 | ≥1.8 |
