Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
As shown in Figure 1, including the following steps: that (1) construction is quasi- the present invention provides a kind of useless rubber plastic road surface construction method
It is standby；(2) rubber and plastic height sticks modified pitch processing and storage；(3) rubber and plastic height sticks modified pitch OGFC construction；(4) acceptance of work；(5)
Open to traffic.
Grinding compacting is carried out to lower sleeping bitumen layer in advance in step (1), and lower sleeping pitch layer surface is dried, clearly
It is clean；Guarantee that substrate surface meets the requirements without surface dust and its flatness, road camber degree, just can be carried out OGFC surface layer after meeting examination
Making.
After preparation of construction process, rubber and plastic height is carried out in the place close to paved base site and sticks modified pitch processing and deposits
Storage avoids long-distance transportation from causing the case where cooling down；Include the following steps: in the construction method of step (2)
1. matrix pitch is heated to 170 DEG C~180 DEG C；
2. being heated to 180 DEG C~200 DEG C after rubber powder, waste plastics is added in matrix pitch and being mixed and stirred, the mixing time
For 45min~120min；
3. carrying out reaction 60min under the conditions of 200 DEG C~210 DEG C of temperature after uniform mixing, the glutinous modified drip of rubber and plastic height is obtained
It is green；
4. sticking modified pitch to rubber and plastic height temporarily to be stored under the conditions of 145 DEG C~155 DEG C；
It is sticked in Modified Bitumen Production Procedure carrying out rubber and plastic height, matrix pitch, rubber powder and waste plastics is added separately to
In each holding vessel, while matrix pitch is quickly heated up to 170 DEG C~180 DEG C；Then it is dripped to the matrix for being heated to predetermined temperature
Rubber powder is added in blueness, waste plastics is pre-mixed in blender as after modifying agent, and guarantees to reach in whipping process
200 DEG C~210 DEG C of whipping temp；Matrix pitch after being sufficiently mixed is reacted in reactor tank with rubber powder, waste plastics, instead
Temperature should be kept to be located at 200 DEG C~210 DEG C in the process, can be obtained rubber and plastic height after duration 60min and stick modified pitch.
In above-mentioned steps, rubber powder additive amount is the 2%~4% of matrix pitch weight；The additive amount of waste plastics is base
The 5%~8% of matter pitch weight, waste plastics are those semi-crystalline materials thermoplastic resin；And the main source of rubber powder, waste plastics
It is to be shredded by waste tire, wherein the particle of waste plastics is greater than the particle of rubber powder；So as to largely utilize waste tire,
Environment is protected, the waste of natural resources is reduced.Wherein, matrix pitch will meet the requirement of the quality technology in table 1, modeling of giving up
Material performance meets the technical requirements in table 2, and the chemistry of rubber powder, physical technique index meet table 3, the technical requirements in table 4.
The requirement of 1 matrix pitch quality technology of table

B, it transports, charging method carries out mixture charging before, during and after being used by dumper of the load-carrying greater than 25t, simultaneously
It is covered using the double-deck tarpaulin, transports discharging after paving site；Three sections of chargings, discharging respectively before, during and after, can
Reduce residence time of the mixture on dumper；Before being charged, need to completely being cleaned in dumper, and clear
One layer of anti-adhesion agent is uniformly sprayed after sweeping.
Meanwhile during transportation, there are meet with rainwater in foul or transport not can enter booth then on live road surface if it exists
Spread process；Discharging is carried out after meeting making requirement to pave.
C, pave, clean original ground, by crawler-type paver according to less than 3m/min movement speed to mixture into
Row paves, and coefficient of loose laying is 1.1~1.15；In paving process, dumper should stop at 100m~300m in front of paver,
Into after paving, dumper and paver synchronizing moving guarantee that the temperature of mixture in paving process is met the requirements；It paves
Before, paver screed temperature will be preheating to greater than 100 DEG C；And the surface temperature for the bitumen layer that crouches under in paving process
And paving thickness controls the paving material of mixture, such as table 9, is either paved mixing by low temperature paved mixture or high temperature
Expect, such as table 10, to be kept the temperature using tarpaulin in paving process to control the temperature of mixture.
9 rubber and plastic height of table sticks the minimum paving material of modified asphalt mixture
The paving material of the glutinous modified drip mixture of the different rubber and plastic height of table 10
It can be 8~10m for particulate formula OGFC mixture progress in paving process, and it is mixed for middle grain formula OGFC
Closing material need to be worked at the same time using two pavers when being paved, the lap width of the reserved 30~60cm in centre, and front and back is staggered 10
~20m, the working width of a paver are 6m；Road pavement carries out compaction treatment after the completion of paving.
D, it rolls, is pressed using double-steel wheeled vibratory formula road roller by first pressing, again, road pavement is rolled final pressure respectively；Its
In, first pressing process is a static pressure and three times vibroroller cmpactings, and multiple pressure is three times vibroroller cmpactings, and final pressure is twice of static pressure；It has rolled
Road pavement is sprinkled water after finishing；When progress road surface is rolled, the road roller of use preferably uses the model less than 12 tons of load-carrying, and double
Steel wheel will not be cohered under the glutinous state of height.Such as table 11, table 12, mixture temperature >=150 DEG C during first pressing, rolling speed
For 2~4km/h；Mixture temperature >=110 DEG C during multiple pressure, rolling speed are 3~4km/h；Mixture warm during final pressure
>=90 DEG C of degree, rolling speed are 3~6km/h；Side is rolled to center outside road surface at level road position, is having sloping position
The place of setting hoists from lower and rolls.
11 rubber and plastic height of table sticks modified asphalt mixture and rolls temperature
12 road roller rolling speed (km/h) of table
| Road roller type | First pressing | Multiple pressure | Final pressure |
| Steel-wheeled vibrated roller | 2~4 | 3~5 | - |
| Static load steel roller | 2~3 | - | 3~6 |
In carrying out roller compaction process, road roller cannot be vibrated using the prime time, avoid excessively compacted between thicker gather materials make
At broken situation；And after the completion of rolling, a small amount of water is sprayed on road surface before road surface is uncolled, to reduce open to traffic
The glutinous band on road surface and tire afterwards acts on.
E, joint treatment；The new mixture of making is carried out to reserved overlapping the slot after rolling to overlap, and can be passed through
Artificial or rock drill vertically excludes the position not gone out regardless of thickness, guarantees the requirement that vertical carvel joint is able to satisfy when seam.
After the completion of entire laying of roadway, road pavement is needed to carry out the acceptance of work, by the way that friendship could be opened after the acceptance of work
