Below, by an embodiment, the present invention is described in detail.
In the present embodiment, the job location of colored micro-surface area to be laid is an area is 1000m
2small-sized parking lot.
Colored mineral aggregate raw material is selected as follows: wherein particle diameter is the granule building stones consumption of 0 ~ 3mm is 10.8t, particle diameter be 3 ~ 5 large grain building stones consumption be 6.12 tons, red basalt all selected by granule building stones and large grain building stones.Toner selects magnalium toner, and gross weight is 720kg, and limestone dust selected by breeze, and gross weight is 360kg.
The gross weight of light-colored resin class modified emulsifying asphalt is 1.89t; Use cement as Admixture, gross weight is consumption is 180kg, and the gross weight of water is 1.260t.
Respectively granule building stones, greatly grain building stones, toner and limestone dust are added in batch bin and stir, obtain colored mineral aggregate and add in the corresponding feed bin of rare slurry sealing vehicle.In addition, filler, water and light-colored resin modified emulsifying asphalt are added in the corresponding feed bin of rare slurry sealing vehicle.
Construction sequence is as follows:
A, to the repairing on the former road surface in small-sized parking lot, clean, execute sample line, rare slurry sealing vehicle clean, debugging and demarcate, and interim raw material supply base be set near job location put.
During the cleaning of road surface, use special cleaning equipment as air compressor machine wind or high pressure water washing etc., local by hand sweeping, can adopt pavement cleaning during large area.In cleaning process, to communal facility as well lid, valve box, water inlet etc. are covered, prevent the pollution in work progress.
Before construction, should ensure that each conveyance conduit of Modified Slurry Sealing car, conveyer belt, paving box clean, in case the material that last consignment of is left over is on this impact caused of constructing, the control system, road speed etc. of Modified Slurry Sealing car be debugged.
With reference to the indices of laboratory test, in conjunction with mixing and stirring in advance, Modified Slurry Sealing car being carried out to the demarcation of metering system outside the venue, mainly comprising the conveying capacity of mineral aggregate, modified emulsifying asphalt and water, and mix speed, pave slurry mixing speed.
After B, rare slurry sealing vehicle to be modified are in place, according to parameter calibration value when mixing and stirring in advance, after adjusting the height of each bin gate, open and mix the paddle in cylinder and the spiral agitator in paving box.Because the position of mineral aggregate outlet, feeding port, delivery port and modified emulsifying asphalt spout is different, when to start bin gate switch simultaneously, the instantaneous order that each raw material reach paving box is followed successively by modified emulsifying asphalt, water, filler, mineral aggregate, this control method easily causes the mixture segregation bottom paving box, therefore, for ensureing construction quality, should before the actual position that paves preset one block of iron sheet, paver vehicle is constructed from iron sheet position, removes iron sheet afterwards to ensure the construction quality of paving concrete pavement seam crossing.
In addition, overall paving process must carry out according to following step: Modified Slurry Sealing car should according to the breakdown of emulsion state adjustment speed of a motor vehicle of micro-surface area colored in paving box in paving process, slow traveling, pace is under normal circumstances 30m/min ~ 45m/min, and the colored micro-surfacing mixture volume in paving box should be kept at any time to be about 1/2 of paving box volume; Before closing on the end that paves, sump outlet should be closed in advance, close feed bin, modified emulsifying asphalt storehouse and filling container more afterwards simultaneously, prevent at the segregation terminating forward slip value material that paves; After the end that paves, mention paving box, drive in time and clear up to roadside, especially the cleaning of paving box and a mixing bowl.After colored micro-surface area paves and terminates, the reply scene situation that paves is observed in time, to the starting point that paves, terminal, butt, the position such as longitudinal seam carries out manually levelling, and to micro-surface area surface exist blocked up, cross thin and surface and have the positions such as scratch to repair as early as possible.
C, to roll
Because colored micro-surface area is different and common micro-surface area, its binding material is by resin and extracts the synthesis of wet goods material out, therefore when after modified emulsifying asphalt breakdown of emulsion, its binding material self-strength is limited, for strengthening the formation of early strength and accelerating the open to traffic time, available small-sized pneumatic-tired rollers (2t) rolling road surface after colored micro-surfacing mixture reaches initial set.
D, at colored micro-surface area open to traffic after 1 ~ 2 month, gather materials in micro-surface area layer, pitch redistributes and be in stable state under tire rubbing effect, pitch oil film, the unstable coarse aggregate that bonds on micro-surface area layer surface peel off under driving effect, simultaneously because the time that is open to traffic is not long, the function of surface of micro-surface area does not also significantly decay.Testing index now really can reflect that the initial stage service performance of micro-surface area is most suitable.Therefore, the suggestion micro-surface area final acceptance of construction time, according to the size of the traffic volume, can carry out when 1 ~ 2 month after open to traffic.Its final acceptance of construction quality examination mainly comprises surface quality, cling property, thickness and water resistance.
Table 1 is red basaltic technical indicator, and table 2 is the basic index of breeze, the technical indicator of table 3 light-colored resin class modified emulsifying asphalt.All test methods in the present embodiment come from China's " standard specification for construction and acceptance of highway asphalt pavement ", and T0316 etc. are the code name of each method of testing.
