Description
Technical field
The present invention relates to a kind of Hydraulic and Hydro-Power Engineering compaction type asphalt concrete face slab impervious barrier protection, building surface antiseepage
Coating and the material of deck paving, particularly to a kind of aging-resistant bitumastic material and preparation method thereof.
Background technology
One layer of Colophonium agate hoof will be brushed in the impervious barrier surface of the dam asphalt concrete anti-seepage panel of Hydraulic and Hydro-Power Engineering
Fat protects, and conventional bitumastic ageing resistace is low, produces aging in being exposed to the sun for a long time of daylight；Building surface at present
Anti-blend deck paving bitumastic also because ageing resistace is low, after using several years, just there is catabiosis.
Bitumastic is a kind of bitumastic being made up of Colophonium, fiber stabilizer, sand powder and a small amount of fine aggregate
Fill the coarse aggregate skeleton dwell set all-in-one-piece asphalt of gap grading.Have high-load coarse aggregate, high-load breeze,
Bigger asphalt content, the compositing characteristic of low content median diameter granule.The coarse aggregate of high-load is particle-surface and face in compound
The skeleton that directly contact, mutual interlocking are constituted directly bears load action, and the temperature sensitive property of this skeleton is little.Content is higher
Breeze and Colophonium form thing as a form of gel---the matizhi that cohesive strength is the highest so that the overall mechanical property of compound improves.
The effect of these two aspects makes compound have enough vertical and sidewise restraint, under the effect of vehicular load, does not produces or only
Produce small permanent deformation.
Summary of the invention
In view of the deficiencies in the prior art, present invention aim at providing.
Technical solution of the present invention is as follows:
A kind of aging-resistant bitumastic material, described matizhi material includes the component of following weight portion:

Preferably, described matizhi material includes the component of following weight portion:
Colophonium 100 parts, cement 120 ~ 135 parts, 135 ~ 145 parts of sand.3, according to the bitumastic material described in claim, its
It is characterised by: described cement is Portland cement.
Preferably, described sand is sand or the natural sand of artificial, modulus of fineness 2.4～2.8.
It is further preferred that soak 72 hours under the conditions of described bitumastic material room temperature (20 ~ 22 DEG C), test material
Water absorption rate is less than the 0.6% of test specimen weight.
The method making described bitumastic material, comprises the following steps:
1) sand, Colophonium heat respectively；
2) sand after room temperature cement being joined step 1) heating stirs, after stirring, adds the heating of described step 1)
After Colophonium in be stirred；
Complete bitumastic material making.
Preferably, described step 1) sand is heated to 155～160 DEG C, and Colophonium is heated to 135～150 DEG C.Suitable by using
Mixture temperature, it is ensured that bitumastic mix homogeneously, stable in properties, improve its ageing resistace.
General-purpose cement is primarily referred to as: six big class cement of GB175 2007 regulation, i.e. portland cement, normal silicate
Cement, portland slag cement, Portland pozzolana cement, Portland fly ash cement and composite Portland cement.
1) present invention uses is Portland cement (P.O), and its meta-alkalescence is big with the Colophonium adhesion of meta-alkalescence；
2) cement fineness modulus is little, big with the bonding area of asphaltene molecule；
3) cement water suction is with regard to the characteristic of stiffization.
Due to the characteristic of cement, the cohesiveness of the bitumastic of the present invention is big, and the addition of cement makes bitumastic exist
Trickling value under hot conditions is low, makes the bitumastic of invention not trickle when Exposure to Sunlight, not ftracture, thus extends it at high temperature
Time life-span.
The present invention has the beneficial effect that:
1, the invention provides a kind of Hydraulic and Hydro-Power Engineering compaction type asphalt concrete face slab impervious barrier protection, building surface antiseepage
Coating and the material of deck paving, the manufacture of materials of the present invention is simple, cheap, easily realize, and rolls for Hydraulic and Hydro-Power Engineering
The protection of formula asphalt concrete face slab impervious barrier and the material of building surface barrier coat provide new has aging-resistant material.
2, manufacture of materials of the present invention trickling simple, cheap, low and ageing resistace are strong, and service life is long.
3, material ageing resistace of the present invention is strong, trickling value is low, and the bitumastic solving brushing just occurred after several years
An aging difficult problem.
4, raw material is readily available, and cost ratio is relatively low, good and cheap, practical.
5, the bitumastic of usual material soaks 24 hours in room temperature (20 ~ 22 DEG C), and water absorption rate is about the 1% of test specimen.This
The material of invention is lower than usual material by 35%～40%.
6, the slope trickling situation of usual bitumastic:
During temperature 95 DEG C, 45 ° of gradient states are shelved 4 hours and are not trickled, without foaming phenomena；
During temperature 120 DEG C, 45 ° of gradient states are shelved 1 hour and are not trickled, without foaming phenomena.
The slope trickling situation of bitumastic of the present invention:
During temperature 100 DEG C, 45 ° of gradient states are shelved 7 hours and are not trickled, without foaming phenomena；
During temperature 120 DEG C, 45 ° of gradient states are shelved 3 hours and are not trickled, without foaming phenomena.Show the trickling value of material of the present invention
Low, aging resistance characteristic is strong.
