Abstract

The utility model relates to a road surface glass fiber reinforcing sub-seal layer structure, which comprises a fiber asphalt mixed layer and a gravel layer paved on the fiber asphalt mixed layer. The fiber asphalt mixed layer is paved in three layers, a first layer is paved with modified emulsified asphalt, a second layer is paved with the modified emulsified asphalt and glass fiber synchronously, and a third layer is paved with the modified emulsified asphalt. By the adoption of the novel sub-seal layer structure, reflection cracks of a semi-rigid base-layer asphalt surface road can be effectively suppressed, interlayer bonding is ensured, and service life of the semi-rigid base-layer asphalt surface road is prolonged.

Description

The road surface glass fiber strengthens seal structure down
Technical field
The utility model relates to a kind of structure between bituminous pavement top and basic unit, is applicable to the following seal of semi-rigid asphalt pavement.
Background technology
Because the restriction of factors such as economy, bituminous material and construction technology; Flexible pavement is built according to the guiding theory of " strong basis, sake, steady soil matrix " by China; Make that like this Pavement on Semi-rigid Type Base structure has occupied the overwhelming majority in the flexible pavement; According to investigations, the about flexible pavement more than 90% of China has used semi-rigid type base.Along with a large amount of uses of semi-rigid asphalt pavement, progressively find there is some serious problems, form reflection crack because this semi-rigid sub-base material is prone to cause base course crack at asphalt surface course, thereby cause or quicken the destruction of flexible pavement.At present China's highway semi-rigid asphalt pavements at different levels generally adopt mulseal seal technology to make down seal, and its cracking resistance and water resistance do not reach desirable effect, some engineering even the interlayer cohesive action is being played negative effect.
Summary of the invention
The utility model technical problem to be solved is: the reflection crack of semi-rigid asphalt pavement.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of road surface glass fiber strengthens seal structure down, comprises the macadam of spreading on fiber asphalt mixed layer and the fiber asphalt mixed layer.
The fiber asphalt mixed layer divides three layers to spill cloth, and first floor spills the cloth modified emulsifying asphalt, and the second layer spills cloth modified emulsifying asphalt and glass fiber synchronously, and the 3rd layer is spilt the cloth modified emulsifying asphalt.
The beneficial effect of the utility model is: adopt after the said structure, can effectively suppress the semi-rigid asphalt pavement reflection crack appearance, guarantee that interlayer coheres, prolongs the application life of semi-rigid asphalt pavement.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, fiber asphalt mixed layer; 2, macadam.
The specific embodiment
A kind of road surface as shown in Figure 1 glass fiber strengthens seal structure down, comprises the macadam 2 of spreading on fiber asphalt mixed layer 1 and the fiber asphalt mixed layer 1.
It is to adopt task equipment to divide to spill for three times cloth (spill the cloth modified emulsifying asphalt for the first time, spill cloth modified emulsifying asphalt and glass fiber for the second time synchronously, spill the cloth modified emulsifying asphalt for the third time) that glass fiber strengthens down the seal structure, then a kind of novel seal structure down that forms of spreading aggregate above that.Glass fiber filaments after the fragmentation forms uniform random phase net structure, has increased the intensity of seal under the pitch, thereby stops crack reflection in the basic unit to asphalt surface course effectively.
Mechanized constructions are all adopted in the construction of this deck, adopt fiber synchronous cutting pitch flusher wholly computer controlled, adopt crushed stone sealing car spreading rubble, give full play to the mechanization advantage, increase work efficiency and guarantee workmanship.
Material requirements and consumption: modified emulsifying asphalt adopts the AWP-1000 modified emulsifying asphalt, and it is 2.0~2.6kg/m that emulsion is spilt the cloth amount 2(be equivalent to asphalt content and be not less than 1.0 kg/m 2); Glass fiber adopts alkali-free glass fibre, and the unit area consumption is 100~150g/m 2The rubble specification is 5~10mm, and consumption is 6~8m 3/ 1000m 2
The key step of making seal structure under this road surface is:
1, basal plane clean out, smooth, guarantee that basal plane is firmly solid, dry.
2, the first float cloth.After cleaning out, spills basal plane cloth first pass modified emulsifying asphalt (0.6~0.8kg/m 2), to guarantee that modified emulsifying asphalt can infiltrate basic unit's pore, make it have the adhesion stress of enough hard intensities.
3, carry out the fiber synchronous cutting for second time and spill cloth.Be injected in fiber uniformly the discharging opening of spray gun during spraying with special spraying equipment simultaneously, make fiber and modified emulsifying asphalt evenly mix.Fiber consumption is 100~150g/m 2, the modified emulsifying asphalt consumption is 0.8~1.1kg/m 2
4, the 3rd float cloth modified emulsifying asphalt covering layer, scrutiny have or not irregular or leak spray place also to be repaired simultaneously.Guarantee that at last whole basal plane does not have the spray of leakage, plays the drum place, the modified emulsifying asphalt consumption is 0.6~0.7kg/m 2
5, spreading gathers materials.Gather materials specification 5~10mm, quantity 6~8m with aggregate spreader or artificial spreading 3/ 1000m 2, sticking wheel degree of being when rolling.
6, roll.Roll two to four times with rubber-tyred roller.
Implementation consideration:
1, pitch sprinkling car is equipped with and is applicable to that different denseness pitches spray the nozzle and the manual spray gun that uses of usefulness, the pitch sprinkling car spray less than the place adopt manual the sprinkling.
2, before the formal construction, whether the paragraph of selecting length to be not less than 200m earlier tries to spray, strengthen complete intelligent bituminous sprinkling wagon with testing fiber and move normally, and whether measure accurate.
3, spill cloth 5~10mm rubble, make regular check on the rubble spreading amount, guarantee the requirement of rubble coverage scale 70~80%.
4, broken stone distributor should be continuously, evenly go, avoid shutting down as far as possible, avoid neglecting and neglect slowly soon, be beneficial to ensure the uniformity of pitch thickness and building stones.
5, after the seal construction finished under glass fiber strengthened, forbid other vehicle and machinery current, the travel speed of compound transport vehicle on seal under the glass fiber enhancing must not be higher than 10Km/h.
6, district neighbouring works and surface of trees are sprayed in protection, are polluted in order to avoid spatter pitch, when it is subjected to polluting, in time remove.

Claims (2)

1. a road surface glass fiber strengthens seal structure down, it is characterized in that: comprise the upward macadam (2) of spreading of fiber asphalt mixed layer (1) and fiber asphalt mixed layer (1).
2. road surface according to claim 1 glass fiber strengthens seal structure down; It is characterized in that: described fiber asphalt mixed layer (1) divides three layers and spills cloth; First floor spills the cloth modified emulsifying asphalt, and the second layer spills cloth modified emulsifying asphalt and glass fiber synchronously, and the 3rd layer is spilt the cloth modified emulsifying asphalt.
