Description
Technical field
The present invention relates to road surface construction technical fields, and in particular to a kind of high viscoelastic rubber modified bitumen road surface and its construction
Technique.
Background technique
As China road construction section is increased, economic development is rapid, but the pressure-bearing load on road surface is also caused to aggravate, shape
At the damage on road surface.Traditional bituminous pavement refers to the road surface for making surface layer with bituminous concrete.Have through artificial selection certain
The mineral aggregate (rubble or grating gravel, aggregate chips or sand, miberal powder etc.) and a certain proportion of bitumen for road use material of gradation composition, stringent
Mixture made of mixing under control condition.Bituminous concrete is different by binder used, can be divided into dripping with coal for asphalt
Green two major classes;Also there are use in some countries or mix bitumen mixing.By kind difference used of gathering materials, can divide
It is the most universal with rubble use to be rubble, gravel, chiltern, slag several classes of.But traditional drip table road surface is using
When, there are pavement usage for a period of time after, damage it is more serious, need periodically irregularly carry out maintenance, the maintenance time
It is short, cause maintenance costs to increase.This department uses high viscoelastic rubber modified bitumen road surface, removes from office to traditional bituminous pavement
Newly.
Summary of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of high viscoelastic rubber modified bitumen roads
Face and its construction technology, compared with the identical traditional asphalt road surface of structural thickness, damage development is slower for it, especially opens anti-
It splits aspect and shows excellent performance, so that the maintenance period in later period lengthens, reduce maintenance cost.
A kind of high viscoelastic rubber modified bitumen road surface of the present invention and its construction technology, bituminous pavement include base
Layer, waterproof compound geogrid is equipped in base, waterproof compound geogrid has poured modified emulsifying asphalt, is formed under pitch
Layer;It is equipped with the rubber asphalt layer of 6cm in the pitch lower layer, is equipped with modified emulsifying asphalt adhesion coating on rubber asphalt layer, changes
Property emulsified asphalt adhesion coating on be equipped with the high viscoelastic rubber modified bitumen of 4cm, form road surface main layer;Described road surface main layer or so two
Side is correspondingly arranged on flat rock layers, is provided with kerbstone layer on the outside of flat rock layers;The row of being provided at left and right sides of road surface main layer middle and lower part
Water blind pipe;
Its construction technology uses following steps:
Step 1:Raw material prepare:
(1) coarse aggregate:, cleaning hard using stone matter is free of weathering particle, nearly cubic granules coarse aggregate, basalt, brightness
Greenstone coarse aggregate;
(2) fine aggregate:Aggregate chips;
(3) filler:The miberal powder ground using hydrophobicities building stones such as the strong basis rocks such as limestone or magmatic rock, should be loose,
Without other soil, impurity and granule;
(b) modified emulsifying asphalt:It paves before asphalt, sub-surface needs spraying modified emulsified asphalt, spreading amount
0.6~1.0L/m2, modified emulsifying asphalt evaporated residue content are not less than 50%;
Step 2:In parts by weight by step 1 chinese raw materials:5-15 parts of coarse aggregates, 10-25 parts of fine aggregates, 2-4 parts fill out
Material, 2-12 parts of cementitious matters, 35-65 parts of cementitious matter mixing, form rubber-asphalt mixture;
Step 3:Rubber-asphalt mixture paves:
(1) bituminous mixtures for pavement surface is preferably paved using crawler-type paver, paving width according to road surface developed width several
It paves;
(2) it continuously and stably paves, is to improve the main measure of surface evenness.The spreading speed of paver should be according to mixing
With the yield, Mechanical Equipment Matching situation and paving thickness, paving width in building, selected by 2~4m/min, accomplish slowly,
Uniformly, it paves incessantly;
(3) before not being compacted with the mixture of machine spreading, construction personnel, which must not enter, to be trampled;
(4) paver should be adjusted to optimum Working, and the mixture in spiral distributor is to be slightly above spiral distributor
2/3 is degree, is consistent the height of mixture before the baffle of screed within the scope of overall with, avoids paving layer from isolation occur existing
As;
(5) detection loose laying depth, generally 1.08~1.22, screed should be preheated to predetermined temperature before spreading out, and paver is pressed
Plate must splice closely, mustn't have gap, prevent from being caught in pellet that paving is pulled out streak;
Step 4:Rubber-asphalt mixture compacting:
The compacting of bituminous pavement is preferably rolled with steel roller, and the principle progress closely followed, pressed slowly should be followed by rolling.Mixture
It followed by must start to roll under the condition of high temperature as far as possible after paving, must not be stopped on bituminous pavement;It must not be in low temperature shape
It is rolled repeatedly under state, prevents from grinding off building stones corner angle, crushing building stones, destroy building stones embedded squeezing;
(1) wheelmark of road roller should be overlapped 1/3~1/4 and roll width;
(2) road roller should be rolled with even speed;
(3) to loose laying depth, roll sequence, number of rolling, rolling speed and roll temperature should set special messenger check.It answers on road surface
Strict control number of rolling, prevents overrolling.As in roller compaction process discovery have asphalt mastic float or building stones crushing, corner angle it is bright
When aobvious abrasion waited the phenomenon that rolling, rolling should stop;
(4) static road roller steel wheel rolls, hits road side stone peace stone, causes the damage of kerbstone peace stone;
(5) compacting is completed to be down to room temperature to temperature, can allow vehicle pass-through.
Further, the caliber of the draining blind pipe is the draining blind pipe that diameter is 5cm.
Further, the cementitious matter is by weight by 35-75 parts high viscoelastic rubber modified bitumen, 10-15 parts of rubber drips
Green, 20-45 parts of modified emulsifying asphalt compositions.
Further, the high viscoelastic rubber modified bitumen is by weight by 60-75 parts of 110# asphalt, 5-15 parts
