Description
Technical field
The present invention relates to road and bridge construction field of material technology, and in particular to a kind of bridge modified asphalt material and
Preparation method.
Background technique
With the fast development of highway in China traffic, the Large Span Bridges across great rivers are increasing, bridge security
And common concern of the problem of service life by society.Waterproof between bridge deck pavement and between pave-load layer and panel is viscous
Tying safety problem caused by layer failure is focus concerned by people, to the research of bridge deck pavement material and pavement technique at
For one of the key points and difficulties of large bridge construction.
High-grade road of mating formation at present is become with its excellent performance using epoxy bitumen material as the modified asphalt material of representative
The critical material in face and bridge floor.This kind of material is usually one kind with thermosetting resin modified asphalt material, makes thermoplastic pitch
Fundamentally it is changed into thermosetting material, assigns the excellent mechanical strength of modified asphalt material, flexibility, fatigue performance, resistance to
The features such as high-temperature behavior and corrosion resistance, is widely used in big-span steel bridge, tunnel road surface, airfield runway, harbour etc.
Mat formation on Heavy Traffic road surface.
As bridge floor interlaminar bonding material, the epoxy bitumen material as obtained from adding epoxy resin in pitch has
Preferable effect.However, the viscosity due to bituminous epoxy is larger, require construction temperature higher in construction, also to have certain
Operable time, so increasing difficulty of construction；In addition, pitch can be made to become fragile after adding epoxy resin in pitch, it is flexible
Property be deteriorated, it is bad with the followability of bridge panel.Existing bridge is mated formation with epoxy bitumen material weatherability, corrosion-resistant, resistance to height
Warm nature can be poor, affects its service life, increases later maintenance cost.
Chinese invention patent CN101735623A discloses a kind of warm mixed epoxy bitumen material and preparation method thereof, including A
Component and B component.Component A is epoxy resin, B component include pitch 40wt%~83wt%, maleic anhydride 5wt%~
20wt%, 9- octadecenyl amine 10wt%~30wt%, poly sebacic polyanhydride or poly- azelaic acid acid anhydride 2wt%~10wt%；Component A and B
The mass ratio of component is 1:3~5.8.Medium temperature mix can be used, reduce gas discharge when construction, while solving general epoxy
The short problem of pitch operable time.But when preparing B component, maleic anhydride is added to and needs to stir 4~6 in pitch
Hour, it then also needs to add other components, preparation time is too long, influences production efficiency.In addition, bituminous epoxy is although can mention
High Coating combination, but pitch can be made to become fragile after adding epoxy resin in pitch, flexibility is deteriorated.
Therefore, develop that a kind of flexibility is good, high-low temperature resistant good stability, Weatherproof ageing-resistant performance, corrosion resistance and machinery
Excellent in mechanical performance, bridge with long service life are accorded with the demands of the market with modified asphalt material, to promotion road communications vocation
Fast development has very important significance.
