The ready-mixed concrete includes step, by sand in 32.5R portland cement 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, every tray concrete stirring
160-200s；The build demand of field concrete road surface can preferably be adapted to by choosing the portland cement that intensity is 32.5R, by force
Du Yuegao base road surface external force resistance damage capability is bigger, and corresponding manufacturing cost is also higher, selects 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, the shear behavior of concrete can be increased, the concrete road surface on the ridge of field is not easy to slide, moisture penetrate into the case where
Also it can guarantee performance.Flyash, is the fine ash that catching is got off from the flue gas after coal combustion, and flyash is coal-burning power plant's discharge
Primary solids waste.The main oxides of the general flyash in China form are as follows: SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2
Deng.Addition flyash be advantageous in that the workability that can improve 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) improve workability,
Reduce separation；(2) cementitious material, filler aggregate gap are provided；(3) secondary response for utilizing flyash and cement, increases the later period
Intensity reduces cement consumption and reduces heat of hydration temperature rise；(4) it reduces environmental pollution, reduces its danger to water, air and soil
Evil；(5) closely knit smooth rolling compacted concrete pavement is provided.
In time for the mixing quality for guaranteeing grinding coagulation soil mixture and supply, in the particular embodiment, construction uses 1
Platform BH300 type forced stirring equipment is produced using automatic blending, can be supplied per hour using 1 zl50 loading machine feeding
The grinding coagulation soil mix of 50-80t.Because its water consumption is few, the mixing time will be grown grinding coagulation soil compared with normal concrete.It rolls
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 when construction
180s or so.The workability of grinding coagulation soil mix, cohesiveness and plasticity can be improved after extending the mixing time.
Specifically, the transport of grinding coagulation soil preferably uses dump truck, causes to reduce moisture evaporation in transportational process
Consistency loss, should keep wet in wagon box, transportation range should be advisable with the accessible distance of 30min, while be taken necessary
Covering methods.Equipped with 5 12t dump truck transports, transportation range is about 2km for general construction.
The spread concrete includes step, infiltrates base, with land leveller spread concrete, paving for spread concrete is
Number 1.1-1.3, compacted thickness 27-33cm.In some preferred embodiments, pave coefficient 1.2, compacted thickness 30cm；Infiltration
Base can prevent base from absorbing the moisture in concrete, improve the quality of concrete, and grinding coagulation soil design thickness is 30cm,
Paving thickness is up to 36cm after considering coefficient of loose laying, the paving thickness beyond general paver, therefore level land is used in construction
Machine paves.Coefficient of loose laying is the ratio of paving thickness and compacted thickness, it is the important parameter for controlling construction quality, formally
It should be determined by examination paving before construction.Coefficient of loose laying when this paves is 1.2.Rolling compacted concrete pavement designs compacted thickness
30cm, too thin to cannot withstand agricultural machinery walking, resistance to compression, shear resistance are poor, too thick and uneconomical, high expensive of building the road.
The step that rolls is pressed 1-2 times again including vibrating first pressing 1-2 times, not opening vibration, then uses rubber-tyred roller progress whole
Pressure.Specifically in some embodiments, step is rolled with 30m and rolls section, spreading speed 1.5-2m/min for 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.
The factor for influencing consolidation effect mainly rolls length of work segment, rolls order, rolling speed, number of rolling and ring
Border condition etc..
(1) roll segment length: with the evaporation of moisture, concrete consistence is increasing, and compressibility worse and worse, rolls not
It will cause compactness deficiency in time, influence grinding coagulation soil intensity.On the other hand, it is got over since mixing and stirring to molding time interval
Long, the loss of strength of maturing is bigger.It therefore, is guarantee pavement strength, it is necessary to keep the road surface after paving as early as possible
It is compacted.Wish to shorten and rolls length of work segment.But it rolls too short, necessarily road roller is caused frequently to commutate, increase, which rolls, to be connect
Head, 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 every linear meter(lin.m.) be long to be reached the theoretical density 7t that must pave and mixes and stirs the actual conditions of material.This is constructed the length that paves every time
30m is one and rolls section, and in 30min, the rolling operation time was controlled within 1.5 hours for the time control that paves.(2) it rolls secondary
Sequence: it rolls requirement and reaches complete thick closely knit and shaping surface, Ying Caiyong vibrated roller carries out.Roller compaction processes generally have first pressing (quiet
Pressure), several sub- processes such as multiple pressure and final pressure.First pressing main function is to improve dense surface degree, will not be generated in vibroroller cmpacting
The damaged surfaces phenomenons such as passage occur, and provide basis for vibrating compacting.The vibrated roller that multiple pressure can be used is not opened vibration and is carried out,
It rolls 2 times.Multiple pressure is to keep road surface through thickness closely knit, reaches regulation compactness, need to open vibration and carry out, and muller overlapping is preferably to take turns wide 1/
3~1/2, impression is eliminated with benefit, improves flatness.Compressed times and road roller performance, Roller Compacted Concrete Dam mix proportion, road surface thickness
And to roll lap related, and generally 5 times, suitable vibration frequency and amplitude are selected in roller compaction process, it is rear high for first low frequency
Frequently.Final pressure is a kind of indispensable roller compaction processes, preferably uses rubber-tyred roller, and kneading action can disappear when rubber-tyred roller rolls
Except steel wheel impression and fine cracks, and while rolling, can be formed with the surface macro texture for being conducive to improve pavement skid resistance condition, and one
As roll 2 times, rubber-tyred roller is the rolling apparatus used of most having ready conditions in final pressure process.This construction first pressing, multiple pressure use
