Abstract
The invention relates to a modified emulsion asphalt, which is composed of the following components by mass: 45%-55% of matrix asphalt, 1%-1.5% of an emulsifier, 2%-4% of a modifier, 0.2%-0.5% of a stabilizer, and the balance water. According to the invention, the modified emulsion asphalt is prepared by rational proportioning of the raw materials, the bonding capacity of the modified emulsion asphalt is enhanced, and accordingly the pavement performance of a micro-surfacing mixture is improved, and the service life of the micro-surfacing mixture is prolonged.
Description
Technical field
The present invention relates to a kind of asphalt production technical field, particularly relate to a kind of modified emulsifying asphalt.
Background technology
Along with the construction of China's motorway and the prolongation of working life, the maintenance work of motorway has become the major tasks of highway in China department.Modified emulsifying asphalt is a kind of emulsified asphalt product adding rubber latex family macromolecule polymkeric substance, both rubber asphalt properties of materials had been drawn, maintain again the advantage of emulsified bitumen, make the elasticity of emulsified bitumen, cohesiveness, toughness and anti-ageing property strengthen, the high-temperature stability of micro-surface area can be improved simultaneously, low-temperature cracking-resistance, force of cohesion, adhesivity, antistripping ability, early strength, water resistance, thus extend its work-ing life, in the making that modified emulsifying asphalt can be widely used in advanced road and routine servicing engineering, especially the treatment process of maintenance of surface micro-surface area must use modified bitumen product, its technical feature quality will directly affect the success or failure of micro zooming.
What the splitting resistance aspect under existing modified emulsifying asphalt stability at high operating temperatures or low-temperature condition was done is not good especially, and viscosifying power is poor, and work-ing life is shorter.
Summary of the invention
The present invention is intended to solve the deficiencies in the prior art, and provides a kind of viscosifying power strong, the modified emulsifying asphalt of long service life.
The present invention for achieving the above object, by the following technical solutions: a kind of modified emulsifying asphalt, is characterized in that, its component and massfraction as follows: matrix pitch: 45% ~ 55%; Emulsifying agent: 1% ~ 1.5%; Properties-correcting agent: 2% ~ 4%; Stablizer: 0.2% ~ 0.5%; Water: add to 100%.
As preferably, described emulsifying agent is quaternary ammonium salt cationic emulsifying agent.
As preferably, described properties-correcting agent is styrene butadiene rubber latex.
As preferably, described stablizer is one or more in polyvinyl alcohol, calcium chloride and ammonium chloride.
The invention has the beneficial effects as follows: the modified emulsifying asphalt that a kind of modified emulsifying asphalt of the present invention adopts the rational proportion of each raw material to prepare improves the viscosifying power of modified emulsifying asphalt, thus improve micro-surfacing mixture pavement performance, extend micro-surfacing mixture work-ing life.
