Abstract
The invention discloses an anti-crack waterproof asphalt pavement structure and a construction method, which relates to the anti-crack waterproof asphalt pavement structure and the construction method for treating crack phenomena of the original asphalt pavement during the middle and late periods or improving surface properties of a cement concrete pavement, in particular to the treatment on the cracks with above the medium level of the original asphalt pavement by adopting the anti-crack waterproof asphalt pavement structure and the construction method in the middle and late periods of crack development of the asphalt pavement. In the technical scheme, the asphalt pavement structure with at least three layers of oil and two layers of stones is paved on the original asphalt pavement to form the anti-crack waterproof asphalt pavement structure. After the original pavement is cleaned, modified emulsified asphalt and gravels or stone chips are sprinkled on the pavement in layers.
Description
One, technical field:
The present invention relates to bituminous pavement top structure and job practices, especially relate to the anti-cracking and waterproof asphalt pavement surface structure and the job practices of punishing original flexible pavement middle and later periods cracking or improving the cement concrete pavement surface property.
Two, background technology:
The crack maintenance of flexible pavement is flexible pavement requisite maintenance content in the operation process.To the flexible pavement incipient crack that the road surface occurs behind the 1-2 that is open to traffic, adopt the cementation of fissures to mend flat place, method packing crack rainwater infiltration passage usually; To flexible pavement be open to traffic middle and later periods that road surface, 3 years left and right sides occurs in length and breadth to crack and check crack crack, the normal punishment methods such as general table place or seal that adopt, have in the time that is open to traffic about 5 years, flexible pavement is had to drop in advance the substantial contribution road pavement and is carried out large repairs owing to large-area cracking destruction.At the initial stage of pavement crack development, the structure function that has road pavement in crack and function of surface all also do not cause serious destruction, adopt well behaved joint filling maintenance can satisfy the instructions for use of road substantially; In the middle and later periods of crack development, ubiquity is to the crack punishment poor effect of the medium above degree of flexible pavement at present, and some highway sections occur large-area damage again soon after the punishment of crack, and the life-span after the punishment of crack has only 1～2 year even shorter usually.Owing to make flexible pavement enter the overhaul phase in advance to asphalt pavement crack punishment improper measures, the life-span of flexible pavement significantly reduces on the one hand; On the other hand, because to asphalt pavement crack punishment improper measures, occurred when annual overhaul bad then, this year having repaiied bad phenomenon in next year, caused the waste of maintenance funds.
Regulation in seal one joint on " asphalt highway construction technique normalizing (JTG F40 2004) " 6.3: the little table of the suitable making place that speedway, Class I highway is had slight damage; Can adopt slurry seal, little table place or the modified bitumen seal that gathers materials to the last seal that is used to improve cling property.But the enforcement of these technology, to prevent original road surface ftracture again and the function life-span of waterproof generally shorter.
Three, summary of the invention
The purpose of this invention is to provide a kind of structure, the simple anti-cracking and waterproof asphalt road surface structure of construction and job practices.
The technical scheme that purpose of the present invention adopted is that its anti-cracking and waterproof asphalt road surface structure is again the asphalt surface course structure of making at least three oily two stones on original top course.
The present invention, original top course is a flexible pavement, or cement concrete pavement.
Four, the specific embodiment of the invention
The concrete enforcement of anti-cracking and waterproof asphalt pavement surface structure following (is example with five oily four stones, thickness 2cm):
(1) preparation on former road surface
In order to guarantee the effect of anti-cracking waterproof layer construction, before spilling the cloth modified emulsifying asphalt, tackle the earth of former road surface and loose material and clear up.
(2) working procedure:
For the first time spill the cloth modified emulsifying asphalt, spilling the cloth amount is 1.0-2.0kg/m2, and spreading 13-15mm rubble also rolls;
For the second time spill the cloth modified emulsifying asphalt, spilling the cloth amount is 0.6-1.5kg/m2, again spreading 3-5mm aggregate chips and rolling;
Spill the cloth modified emulsifying asphalt for the third time, spilling the cloth amount is 0.8-1.5kg/m2, again spreading 8-10mm rubble and rolling;
Spill the cloth modified emulsifying asphalt the 4th time, spilling the cloth amount is 0.6-1.5kg/m2, again spreading 3-5mm aggregate chips and rolling;
Spill the cloth modified emulsifying asphalt the 5th time, spilling the cloth amount is 0.2-0.8kg/m2, roller-compaction.
Claims (5)
1. anti-cracking and waterproof asphalt pavement surface structure, it is characterized in that: making has at least two kinds of single-stages to join rubble or the compound flexible pavement surface texture that becomes at least three inserted oily two stones of aggregate chips on original top course.
2. original top course according to claim 1 is characterized in that: flexible pavement or cement concrete pavement surface layer.
3. the asphalt pavement structure of according to claim 1 three oily two stones is characterized in that: spill cloth once oil back spreading single-stage join rubble or aggregate chips, spill behind the cloth oil again the spreading single-stage for the second time and join rubble or aggregate chips, one deck spills oil more at last.
4. bituminous pavement top structure according to claim 1 is characterized in that: the bituminous pavement top structural thickness is 1.5-3cm.
5. three oil according to claim 1 is characterized in that: modified emulsifying asphalt.
