Description
Technical field
The present invention relates to a kind of protections of hydraulic and hydroelectric engineering compaction type asphalt concrete face slab impervious barrier, building surface antiseepage
The material of coating and deck paving, in particular to a kind of anti-aging bitumastic material and preparation method thereof.
Background technique
The antiseepage layer surface of the dam asphalt concrete anti-seepage panel of hydraulic and hydroelectric engineering will brush one layer of pitch Ma hoof
Rouge protects, and common bitumastic anti-aging property is low, daylight for a long time be exposed to the sun in generate aging；Building surface at present
It is anti-blend deck paving bitumastic also because anti-aging property is low, aging phenomenon just occurs after using several years.
Bitumastic is a kind of bitumastic being made of pitch, fiber stabilizer, emery dust and a small amount of fine aggregate
Fill the integral asphalt of the coarse aggregate skeleton dwell set of gap grading.With high-content coarse aggregate, high-content miberal powder,
The compositing characteristic of larger asphalt content, low content median diameter particle.The coarse aggregate of high-content particle-surface and face in mixture
The skeleton that directly contact, mutual interlocking are constituted directly bears load action, and this temperature sensitive property of skeleton is small.Content is higher
Miberal powder and pitch formed the very high object-- matizhi as a form of gel of cohesive strength so that the whole mechanical property of mixture improves.
The effect of these two aspects make mixture have it is enough vertically and sidewise restraint, under the action of vehicular load, do not generate or only
Generate small permanent deformation.
Summary of the invention
In view of the deficiencies in the prior art, it is an object of that present invention to provide.
Technical solution of the present invention is as follows:
A kind of anti-aging bitumastic material, the matizhi material comprise the following components in parts by weight:
100 parts of pitch, 125 ~ 145 parts of cement, 130 ~ 150 parts of sand.
Preferably, the matizhi material comprises the following components in parts by weight:
100 parts of pitch, 120 ~ 135 parts of cement, 135 ~ 145 parts of sand.3, the bitumastic material according to claim
Material, it is characterised in that: the cement is ordinary portland cement.
Preferably, the sand is the sand or natural sand of artificial, fineness modulus 2.4~2.8.
It is further preferred that being impregnated 72 hours under the conditions of the 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 for making the bitumastic material, comprising the following steps:
1) sand, pitch heat respectively；
2) room temperature cement is added in the sand after step 1) heating and is stirred, after mixing evenly, add the step 1)
It is stirred in pitch after heating；
Complete the production of bitumastic material.
Preferably, the step 1) sand is heated to 155~160 DEG C, and pitch is heated to 135~150 DEG C.By using suitable
Mixture temperature, guarantee bitumastic be uniformly mixed, property stablize, improve its anti-aging property.
General-purpose cement is primarily referred to as: six major class cement as defined in GB175-2007, i.e. portland cement, normal silicate
Cement, portland slag cement, Portland pozzolana cement, Portland fly ash cement and composite Portland cement.
1) for the present invention using being ordinary portland cement (P.O), meta-alkalescence is big with the pitch binding force of meta-alkalescence；
2) cement fineness modulus is small, big with the bonding area of asphaltene molecule；
3) characteristic of the cement water suction with regard to stiffization.
Due to the characteristic of cement, the cohesiveness of bitumastic of the invention is big, and the addition of cement makes bitumastic exist
Trickling value under hot conditions is low, so that the bitumastic of invention do not trickled, cracked in solarization, to extend it in high temperature
When service life.
The present invention has the beneficial effect that:
1, the present invention provides a kind of protections of hydraulic and hydroelectric engineering compaction type asphalt concrete face slab impervious barrier, building surface
The material of barrier coat and deck paving, material of the invention produce simple, cheap, Yi Shixian, are hydraulic and hydroelectric engineering
The material of the protection of compaction type asphalt concrete face slab impervious barrier and building surface barrier coat provide it is new have it is anti-aging
Material.
2, simple, cheap, the low trickling of material production of the present invention and anti-aging property are strong, long service life.
3, material anti-aging property of the present invention is strong, trickling value is low, just occurs after solving bitumastic several years of brushing
The problem of aging.
4, raw material is easy to get, and cost is relatively low, good and cheap, practical.
5, the bitumastic of usual material impregnates 24 hours at (20 ~ 22 DEG C) of room temperature, and water absorption rate is about the 1% of test specimen.This
The material of invention lower than usual material 35%~40%.
6, the slope trickling situation of usual bitumastic:
At 95 DEG C of temperature, 45 ° of gradient states, which are shelved 4 hours, does not trickle, without foaming phenomena；
At 120 DEG C of temperature, 45 ° of gradient states, which are shelved 1 hour, does not trickle, without foaming phenomena.
The slope trickling situation of bitumastic of the present invention:
At 100 DEG C of temperature, 45 ° of gradient states, which are shelved 7 hours, does not trickle, without foaming phenomena；
At 120 DEG C of temperature, 45 ° of gradient states, which are shelved 3 hours, does not trickle, without foaming phenomena.Show the stream of material of the present invention
It is low to drop down value, anti-aging characteristic is strong.
