Fig. 1 is referred to, is a kind of field concrete road surface process for constructing of the invention, as illustrated, method includes following step
Suddenly, preparation of construction S100, ready-mixed concrete S102, spread concrete S104, roll S106；
The preparation of construction includes step, removes soft base soil, flattening foot layer, to ensure that surface evenness is every in basic unit
Measurement control stake is set every 10m or so, measurement control stake is mainly used in controlling elevation.
The ready-mixed concrete includes step, by sand in 32.5R portland cements 270-330kg, 0.25-0.5 millimeter
0.43-0.51m3, 20-40 millimeters of gravel 0.76-0.92m3, flyash 0.06-0.08m3It is stirred, the stirring per tray concrete
160-200s；Choosing intensity can preferably adapt to the build demand of field concrete road surface for the portland cement of 32.5R, by force
Du Yuegao basic units road surface external force resistance damage capability is bigger, and corresponding manufacturing cost is also higher, from the portland cement of 32.5R
The use demand and cost control demand of field concrete road surface can preferably be adapted to.The middle sand of above-mentioned component and making for gravel
With, by increasing capacitance it is possible to increase the shear behavior of concrete, the concrete road surface on the ridge of field is difficult to slide, in the case where moisture penetrates into
Also ensure that performance.Flyash, is catching is got off from the flue gas after coal combustion fine ash, and flyash is coal-burning power plant's discharge
Primary solids waste.The main oxides of the general flyash of China are constituted：SiO2、Al2O3、FeO、Fe2O3、CaO、TiO2
Deng.Addition flyash be advantageous in that can improve the workability of concrete batching system, water-retaining property, reduce hydration heat of concrete,
Improve concrete durability；Specifically, effect of the flyash in concrete has the following aspects：(1) workability is improved,
Reduce and separate；(2) Binder Materials, filler aggregate space are provided；(3) using flyash and the secondary response of cement, the later stage is increased
Intensity, reduces cement consumption and reduces heat of hydration temperature rise；(4) environmental pollution is reduced, its danger to water, air and soil is reduced
Evil；(5) closely knit smooth rolling compacted concrete pavement is provided.
For the mixing quality and supply that ensure grinding coagulation soil mixture are timely, in the particular embodiment, construction uses 1
Platform BH300 type forced stirring equipments, using 1 zl50 loading machine feeding, are produced using automatic blending, can be supplied per hour
The grinding coagulation soil mix of 50-80t.Grinding coagulation soil is few because of its water consumption, and the mixing time will be grown compared with normal concrete.Roll
The concrete mixing time is about 1.5 times of normal concrete.Determine that the control time mixed and stirred is every disk by trial mix during construction
180s or so.The workability of grinding coagulation soil mix, cohesiveness and plasticity can be improved after the extension mixing time.
Specifically, the transport of grinding coagulation soil preferably uses dump truck, in order to moisture evaporation causes in reducing transportation
Denseness loss, wagon box planted agent keep moistening, transportation range should be advisable with the accessible distances of 30min, while taking necessary
Covering methods.General construction is about 2km equipped with 5 12t dump trucks transports, transportation range.
The spread concrete includes step, infiltrates basic unit, uses land leveller spread concrete, and paving for spread concrete is
Number 1.1-1.3, compacted depth 27-33cm.In some preferred embodiments, pave coefficient 1.2, compacted depth 30cm；Infiltration
Basic unit is prevented from the moisture during basic unit absorbs concrete, improves the quality of concrete, and grinding coagulation soil design thickness is 30cm,
Paving thickness is up to 36cm after considering coefficient of loose laying, and level land is used in the paving thickness of general paver, therefore construction
Machine is paved.Coefficient of loose laying is the ratio of paving thickness and compacted depth, and it is the important parameter for controlling construction quality, formally
Should be determined by trying paving before construction.Coefficient of loose laying when this paves is 1.2.Rolling compacted concrete pavement designs compacted depth
30cm, too thin holding can't stand that agricultural machinery is walked, and resistance to compression, shear resistance are poor, too thick and uneconomical, high expensive of building the road.
It is described roll step include vibration first pressing 1-2 all over, do not open multiple pressure 1-2 times of shaking, then end is carried out using rubber-tyred roller
Pressure.Specifically in some embodiments, roll step and roll section, spreading speed 1.5-2m/min with 30m as one.
The key of rolling compacted concrete pavement is exactly to roll work, and the quality for rolling work directly determines the quality on road surface.
Influence the factor of consolidation effect to be mainly and roll work segment length, roll order, rolling speed, number of rolling and ring
Border condition etc..
(1) segment length is rolled：With the evaporation of moisture, concrete consistence is increasing, and compressibility worse and worse, is rolled not
Compactness can be caused not enough in time, influence grinding coagulation soil intensity.On the other hand, since the time interval to shaping mixing and stirring get over
Long, the loss of strength of maturing is bigger.Therefore, it is guarantee pavement strength, it is necessary to make the road surface after paving as early as possible
It is compacted.Wish that shortening rolls work segment length.But roll too short, necessarily cause road roller frequently to commutate, increase is rolled and connect
Head, so as to influence the uniformity and surface evenness of compacting.According to the yield of stirring field 100t/h, 1.5-2m/min's paves
Speed, and the solid density 7t that must pave that reaches long mixes and stirs the actual conditions of material per linear meter(lin.m.).This is constructed the length that paves every time
30m rolls section for one, and, in 30min, rolling operation time control is within 1.5 hours for the time control that paves.(2) roll secondary
Sequence：Roll requirement and reach the closely knit and shaping surface of full thickness, should be carried out using vibrated roller.Roller compaction processes typically have first pressing (quiet
Pressure), several sub- operations such as multiple pressure and final pressure.First pressing Main Function is to improve dense surface degree, will not be produced in vibroroller cmpacting
The damaged surfaces phenomenons such as passage occur, for vibrating compacting provides basis.Can using multiple pressure with vibrated roller do not open to shake and carry out,
Roll 2 times.Multiple pressure is to make road surface through thickness closely knit, reaches regulation packing, and need to open to shake is carried out, and muller overlaps to be preferably takes turns wide 1/
3~1/2, impression is eliminated with profit, improve flatness.Compressed times and road roller performance, Roller Compacted Concrete Dam mix proportion, road surface thickness
And to roll lap relevant, generally 5 times, suitable vibration frequency and amplitude are selected in roller compaction process, be first low frequency, it is high afterwards
Frequently.Final pressure is a kind of indispensable roller compaction processes, and preferably using rubber-tyred roller, kneading action can disappear when rubber-tyred roller is rolled
Can be formed with except steel wheel impression and fine cracks, and when rolling beneficial to the surface macro texture for improving pavement skid resistance condition, one
As roll 2 times, rubber-tyred roller is the rolling apparatus for using of most having ready conditions in final pressure operation.This construction first pressing, multiple pressure are used
Ca25 road rollers are carried out, and final pressure is produced rubber-tyred roller and carried out using Dezhou of large-tonnage.Compressed times reach regulation pressure by detection
Solidity is controlled (generally 3~6 times), and the rolling speed of first pressing, multiple pressure and final pressure is 1.0~l.5km/h.(3) note
