Description
Technical field
The invention belongs to building material surface modifying agent technical field and in particular to a kind of oiliness gather materials-asphalt interface prevent
Rust modifying agent and preparation method and application.
Background technology
China is still in the peak period of high-grade highway construction at present, and bituminous paving is as main pavement structure form quilt
Commonly used.The quality of quality of asphalt mixtures directly affects construction quality of pavement, and then affects the service life on road surface.And
Gather materials in asphalt the quality accounting for 95% about, be the main material of composition asphalt, the quality of its quality
To the mechanical properties and performance of compound, there is strong influence.
In view of the importance in asphalt for the former material that gathers materials, China makes of the pavement performance gathering materials for road
More research, existing standard system proposes clear and definite technical requirements in all many-sides to gathering materials.China《Highway asphalt road
Surface construction technical specification》Remove in (JTG F40-2004) and tool is proposed to the specification (particle diameter, gill shape and mineral nitrogen level are joined) gathered materials
Body requires outer it is also expressly that defining the crush values gathered materials, wearing valve, robustness, polishing value, clay content and gathering materials and Colophonium
The requirement of the aspects such as adhesiveness.Require used gather materials should intensity is high, wearability is good, have good adhesion again with Colophonium
Property.Specifications and the proposition that requires with clearly, the correct selection that specification China is gathered materials and using it is ensured that bituminous paving
Pavement performance there is great guaranteeing role.
The regulation of existing standard system is concentrated mainly on the aspects such as the specification gathered materials, physical and mechanical property.In addition, with regard to changing
Learn the research of element aspect, generally according to silicon dioxide (SiO2) content to lithology (acid, alkalescence or the mesodialyte gathering materials
Material) defined.And for aspects such as the other properties of chemical compositions (chemical element component index) gathering materials, due to Colophonium with
The complexity of surface of aggregate effect and uncertainty, generally get the brush-off in research and engineer applied and are easy to be ignored or letter
Change, more have not been able to form related clear and definite technical specification regulation.
However, just because of the research deficiency to the properties of chemical composition that gathers materials, leading to domestic at present many highways
The generation of Random early Detection.These infringements make express highway pavement quality be greatly reduced, and produce bad and serious impact, cause
Huge economic loss.Road surface get rusty be one one of them have a strong impact on the problem of road quality, part highway is complete
Large-area rust staining in the whole road surface of line, and gathering materials of extraction is divided into cinerouss, white and red three kinds, after tested, contains
Iron is respectively 0.82%, 0.94% and 1.72%, and adhesiveness index all cannot meet code requirement, and wherein, general rust is red
The adhesiveness that color gathers materials is only 2 grades, and remaining two kinds are 3 grades.
For the highway pavement going wrong, testing staff has extracted the sample that road surface gathers materials and has been analyzed.Analysis finds
In gathering materials, some chemical compositions (as iron-holder) can produce to the performance of asphalt and have a strong impact on.Meanwhile, we are complete at present
The each rocks (including diabase, basalt, diabase, granite and sandstone) adopting in entity project in the range of state are all
Containing different degrees of ferrum element, its iron-holder is typically in 2%-10%, but partly commonly uses the content of the ferrum element that gathers materials very
To far above more than 20%.However, not yet having corresponding code regulations, in gathering materials in domestic pavement of road design construction standard
Potentially road quality can be caused with content all no clear stipulaties of the chemical composition of tremendous influence.Thus, thus launch to spy
The research determining relation between chemical composition and Asphalt Mixture Performance will have larger engineering significance.How research avoids
The destruction of middle harmful components road pavement performance of gathering materials, for proper use of carrying to gather materials in pavement engineering project construction process from now on
For technical basis, take precautions against and the generation controlling similar early disease, it is to avoid thus cause huge economic and social benefit to damage
Lose.Related achievement in research, it will be beneficial complement to existing national associated specifications.
