Description
Technical field
The present invention relates to road engineering technical field, a kind of warm-mixed asphalt additive, warm mix are specifically related to
Pitch and Warm-Mix Bitumen Mixture and preparation method and application.
Background technology
Mainly there are two classes currently used for the asphalt of Bituminous Pavement Construction, maintenance：Hot asphalt is mixed
Material and cold mixing (normal temperature) asphalt.Hot-mix asphalt mixture refers to pitch and mineral aggregate in (150 DEG C of high temperature
- 185 DEG C) compound of mix under situation；Cold mixing (normal temperature) asphalt refer to emulsified asphalt or
The compound of cut-back asphalt and mineral aggregate mix, making under normal temperature (10 DEG C -40 DEG C) state.Hot asphalt
Compound is using most, but the noxious gas emission, excessive occurred in mix, transport and paving process
The problems such as energy consumption and heat ageing, is than more prominent；And cold-mix asphalt compound, although in environmental protection, energy consumption etc.
Aspect has great advantage, but due to its pavement performance compared with hot-mix asphalt mixture also larger gap,
Therefore the conserving of bituminous paving, low volume of traffic road surface are only used for, below middle heavy traffic flow road surface layer and
Basic unit.
Exactly in this context, 1990s Europe has started grinding for Warm-Mix Bitumen Mixture
Study carefully, it is a class mix temperature between hot-mix asphalt mixture (150 DEG C -185 DEG C) and cold mixing (normal temperature)
Between (10 DEG C -40 DEG C) asphalt, performance reaches the new of (or close) hot-mix asphalt mixture
Asphalt, its mix and compacting temperature are generally 110 DEG C -130 DEG C.For relatively common pitch,
The mix temperature of modified pitch also needs to improve.The national less use modified pitch such as America and Europe.
It can alleviate hot-mix asphalt mixture well using Warm-Mix Bitumen Mixture to lead due to high temperature mix
The Railway Project of cause：1) the noxious gas emission problem under high temperature.According to external examining report, pitch is mixed
Close material and mixed from heat and switch to warm mix and can make carbon dioxide CO2Discharge reduces by about 1/2, carbon monoxide CO discharges
Reduce by about 2/3, sulfur dioxide SO2Reduce by 40%, nitrogen oxide NOxClass reduces nearly 60%, using warm mix
The environmental benefit of asphalt technology is obviously.2) energy consumption problem.According to foreign literature,
Fuel consumption more than 30% can be reduced using Warm-Mix Bitumen Mixture.3) pitch is old caused by construction at high temperature
Change problem.
Pitch warm mix technology can be divided into three major types according to working mechanism：Foamed asphalt technology；Sasobit
Wax technology and the Evotherm technologies based on surfactant platform.
1) foamed asphalt viscosity reduction technology：Domestic and international product is with Aspha-Min, easily paving 130 and mixing plant
Based on Double Barrel Green, pitch is foamed using water, so as to reduce asphalt viscosity, carried
High asphalt workability.The Aspha-Min consumptions of Eurovia companies suggestion are mixture quality
0.3%, the production temperature than typical hot-mix asphalt mixture reduces 12 DEG C, and construction temperature can be reduced
30℃.It is reported that production temperature reduces by 12 DEG C, power consumption will reduce about 30%.Ground by domestic and foreign scholars
Study carefully and show, without antistripping agent in the case of, compound containing Aspha-Min zeolites is than common drip
The water resistant damage capability of blue or green compound is poor.Other requirement of this technology to mixing equipment is higher.
2) organic viscosity reduction warm mix technology：It is viscous during reduction heated bitumen mix by using organic thinner
Degree, based on wax or wax；Wherein based on Sasobit synthetic waxs, Sasobit is Sasol Wax public
The product of department, it is a kind of TPO Fischer Tropsch waxes, can effectively reduce modified pitch high temperature viscosity,
Reduce mix and forming temperature, Hurley system evaluations use Sasobit Warm-Mix Bitumen Mixture
Performance, it is believed that filled in pitch after 2.5%Sasobit, 129 DEG C of the minimum mix temperature of recommendation, most
It is low to roll 110 DEG C of temperature.Too low mix and roll temperature and will increase the possibility that rut disease occurs,
And too high volume can increase the risk of cold cracking.
3) surface-active warm mix technology：This method is by virtue Wei Shiweike companies of the U.S.
(MeadWestvaco) technology of application was begun one's study and progressively put into 2003, was claimed in the U.S.
For Evotherm warm mix technologies.This method can while mixture performance reaches hot-mix asphalt mixture,
Mix temperature is down to 110 DEG C -130 DEG C.Evotherm warm mix technologies have evolved to third generation warm mix skill
Art, and in China it is familiar be the second generation surface-active warm mix technology, it uses water-based emulsion point
Based on the Evotherm for the technology of dissipating, its action principle is that water-based emulsion agent forms structure moisture film in pitch,
Increase the workability of compound, to reach reduction compound mix temperature, but warm-mixing agent water during mix
Divide a large amount of volatilizations, easily cause the corrosion of equipment and the frequent replacing of filter cloth bag, simultaneously because its warm mix is acted on
Mechanism, it is impossible to directly prepare warm-mixed asphalt, but it is sprayed into mix pot simultaneously with pitch during mix,
Causing addition reforming equipment causes operating expenses to increase, and comprehensive use cost is higher.And third generation product,
For anhydrous type surface-active class warm-mixing agent, it is directly added into bituminous cements, before compound mix,
Warm-mixing agent is added into asphalt tank, is sufficiently stirred for ensureing that warm-mixing agent is dispersed in pitch.The third generation
Anhydrous type surface-active class warm-mixing agent can dramatically increase mix work of the asphalt in lower temperature
The property made, strengthens the adhesive property gathered materials with bituminous cements, improves the service life of road, so its
It is more advantageous in combination property.
Technological development of the China in warm-mixed asphalt field is started late, and country warm-mixed asphalt field is with state at present
Based on outer product.Especially third generation product, anhydrous type surface-active class warm-mixing agent is in great shortage, it is impossible to meet
The application of domestic market, but because its production cost is high, limitednumber, effect is barely satisfactory, and
So that the application of existing warm-mixing agent is limited, it is impossible to really open domestic market, thus exploitation it is a kind of efficiently,
The warm-mixed asphalt additive of advantage of lower cost is urgent problem to be solved.
The content of the invention
Produced the present invention solves the technical problem of warm-mixing agent present in existing warm mix technology is overcome
Cost is high, and energy consumption is big, and limitednumber, effect is barely satisfactory, and there is provided one for the defect such as preparation technology complexity
