Abstract
The invention relates to a high and cold road surface micro-surfacing maintenance method, in particular to a high-grade highway high and cold road surface micro-surfacing preventive maintenance construction method, and aims at providing an effective high and cold road surface micro-surfacing maintenance method. The high and cold road surface micro-surfacing maintenance method comprises the steps that 1, raw materials are selected and comprise pitch, emulgator, additives and macadam and are mixed according to the ratio of 100:1:1:500; 2, aggregation is carried out, that is, modified emulsified asphalt, additives and water are stirred according to the ratio of 100:1:80 to be prepared into modified emulsified asphalt mixtures; 3, filling operation is carried out, then construction is carried out, and during construction, construction conditions are met, preparatory work before construction is carried out, the high and cold road surface micro-surfacing mixtures are paved, and initial maintenance is carried out; 4, construction quality control is finally carried out, and comprises material and equipment check before construction, quality control in the construction process and acceptance check.
Description
Technical field
The present invention relates to a kind of high-grade highway high and cold road surface micro-surface area preventive maintenance construction method.
Background technology
Micro-surface area in time by continuous grading building stones, mulseal, water, filler, modifier mix evenly after complete construction by special laying equipment is disposable, it can according to pavement damage degree, carry out one or more layers cover, micro-surface area is the highest form of emulsified bitumen slurry cover, and it is applicable to the preventive maintenance of important traffic as speedway, urban trunk, airfield runway etc.Micro zooming is invented in Europe at 20 century 70s, fast with its open to traffic, and cling property is remarkable, can repair rut, long service life technological merit, become the pavement maintenance maintenance means that European and American developed countries are important.1999, micro zooming started to be applied popularization in the maintenance of surface process of China Expressway, and it is simple with its construction technology, and cost is low, pollutes little, the features such as open to traffic is fast extremely everybody favor.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of high-grade highway high and cold road surface micro-surface area preventive maintenance construction method, can effective maintenance at High aititude, ultraviolet is strong, temperature is low and the extremely frigid zones road surface that day and night temperature is large.
For realizing above-mentioned purpose of the present invention, the present invention adopts following technical scheme, and the method for high and cold road surface micro-surface area preventive maintenance construction that utilizes of the present invention is.
1. select raw material, raw material comprise pitch, emulsifier, additive and rubble, carry out batch mixing according to the ratio of 100:1:1:500.
2. then gather materials, gather materials and modified emulsifying asphalt, additive, water carried out stirring system by the proportioning of 100:1:80 and be made into modified emulsifying asphalt compound.
3. carry out filler operation, construct afterwards, in construction, accomplish-the initial curing that paves meeting execution conditions-preparative work before construction-high and cold road surface micro-surfacing mixture.
4. finally carry out quality control on construction, before quality control on construction is divided into construction, material and equipment inspection are arrived to the quality control in work progress again and are checked and accepted.
Preferably, described method comprises pitch and selects No. 160 A grade matrix pitches.
Preferably, described method comprises the employing of the coarse aggregate in gathering materials basalt.
Preferably, described method is included in the filler admixture cement, the slaked lime and add organic additive in filler that add in the micro-surface area slurry mixture of high and cold road surface.
The invention has the beneficial effects as follows: not only can cold-resistant anti-low temperature, be applicable to extremely frigid zones, durability and the cling property on road surface can also be improved, extend the extremely frigid zones highway life-span, not only convenient and quick construction, construction technology is simple, cost is low simultaneously, oozes under can effectively preventing road from showing water.
