Description
Technical field
The present invention relates to a kind of modified pitch for building and preparation method thereof, belong to industrial chemical skill
Art field.
Background technology
The actual mass of highway in China still also exists very important problem.With regard to bituminous paving
Speech, road generally also exists that poor durability, service life is short and the problem of earlier period damage, Colophonium
The typical depression in road surface, crack, rut, loose, pit etc. damage in urban road especially
Being seen everywhere, this has had a strong impact on the serviceability of road, causes great economic waste and peace
Full hidden danger.The reason of these pavement damages, except the factor of the aspects such as design, construction, maintenance
Outward, the performance of material, especially asphalt material is also important reason.In general, temperature-sensitive
Weak, the high-temperature behavior of property and cryogenic property is good, ageing resistance and the strong asphalt material of stability can make
Significantly improve the serviceability of road.The performance of existing road asphalt and modified pitch is some side
Face can not meet the needs of pavement performance, adds the development with national economy, Modern Traffic axle
Load-carrying, the volume of traffic is big and inner pressure of tire is high, and road pavement it is also proposed higher requirement, therefore,
Develop that to possess the asphalt material of higher performance be the key solving China's path problem, and Colophonium
The development of modification technology, making the improvement of asphalt performance and the raising of performance of asphalt mixture become can
Energy.
Develop outside Current Domestic modified pitch have multiple, be most commonly used that SBS, SBR
Deng polymer modifiers.These polymer modifiers have respective performance characteristics, can be at certain
Or certain several aspect improves the performance of Colophonium, make road surface disease resistance ability improve, extend road
Service life.But, polymer modifiers mostly is nonpolar, with Colophonium proportion, molecular weight
Difference is relatively big, and therefore they have thermodynamic phase, easily with the co-mixing system of matrix pitch
Produce isolation；Meanwhile, the colloid in asphalt component, asphalitine are polarity, polymer and polarity
The adhesion of material is weak so that Stress Transfer efficiency is low, causes properties of product undesirable；And
Polymer modifiers expensive, complex manufacturing, need the special equipments such as colloid mill,
Energy consumption is serious, is not suitable for applying in China's road construction.
Modern society is due to traffic flow and travels frequency sharp increase, and the axle weight of freight is constantly
Increase, generally carry out divided lane one-way traffic, it is desirable to improve road surface resistance to flow further, i.e.
The ability of Rut resistance under high temperature；Improve flexible and elastic, i.e. the ability of cracking resistance under low temperature；Carry
High abrasion consumes energy power and increases the service life.Existing asphalt has been not suitable with road environment
Change, it is therefore desirable to modified pavement asphalt.
