Description
Technical field
The present invention relates to a kind of modified emulsifying asphalt material of repairing the roads and building the road, specifically is exactly wide territory, high sticking, high-performance modified emulsified bitumen.
Background technology
In the past, the sticker that road bedding is used mainly used place mat to use straight-run pitch.Yet; Along with the volume of traffic increases; The rut impression that causes owing to flowing, crackle etc. are remarkable, and the measure that this is taked is to use modifying asphalt, and pitch is as a kind of high-molecular hydrocarbons of complicacy; Under certain temperature and loading action, show as typical bullet one a sticking plasticity, and under high temperature and uviolizing, can produce catabiosis.Therefore the main purpose that adds properties-correcting agent is exactly to improve asphalt pavement performance at high temperature, improves the performance of aspects such as its anti-rut, antifatigue, anti-aging and opposing cold cracking.
At present, the domestic polymkeric substance kind that is used for asphalt modification is various, and conclusion is got up, and is broadly divided into three types:
(1) modified rubber class: like tree elastomer (NR), styrene-butadiene rubber(SBR) (SBR), X 050 (cR), divinyl rubber (BR), ethylene-propylene rubber(EPR) (EPDM), waste and old doughnut etc.;
(2) thermoplastic elastomer: like styrene-butadiene one styrene block copolymer (SBS), vinylbenzene one different diene one styrene block copolymer (SIS);
(3) resene: comprise thermoplastic resin and thermosetting resin.The former has Vilaterm (PE), ethene one acetic acid, one ethylene copolymer (EvA), gathers second chlorine alkene (PVC).
(4) adopt the method for physics to realize polymkeric substance to the bituminous modification, like heated and stirred, shearing, colloidal mill etc., though the method for physically modified increases the bituminous performance, over-all properties is not still improved at all.
Because SBS costs an arm and a leg and the situ production required equipment is huge and operation very bothers, cause the on the high side of modified bitumen product in addition, do not have price advantage, be unfavorable for the marketing application.Therefore, press for adopt chemical modification method and optional price ratio preferably properties-correcting agent come road bitumen is carried out modification.Especially wide territory, high sticking high-performance modified emulsified bitumen; Because traditional modified emulsifying asphalt (JTG F40-2004); High low temperature and cohesive strength index are lower; And possessing high-temperature stability (index: softening temperature is greater than 60) and low temperature flexibility (index: 5 ductilities are greater than 150CM) simultaneously, cohesive strength high (0.6MPa) does not also have a kind of emulsified bitumen that can use practice of construction at present.It specifically is exactly the modified emulsifying asphalt material of repairing the roads and building the road.
