A kind of bituminous asphalt modifier with high viscosity and production method thereof of being soluble in
Technical field
The invention belongs to the ground surface material technical field, be specifically related to asphalt modifier with high viscosity and production method thereof that a kind of traffic route road surface is used.
Background technology
Thickness is generally the wearing course of 4~5cm to a kind of voidage up to 20%~25%.Because voidage is big, rainwater can infiltrate among the road surface, is drained to pavement edge by the connectivity gap in the road surface, there is not very thick moisture film in the rainy day road surface like this, the generation of having avoided water to float the phenomenon that dabbles also no longer occurs simultaneously, has guaranteed the safety of driving effectively.Because the draining soon of this lacunose road surface, so this road surface is referred to as drainage asphalt pavement (Draining AsphaltPavement).
Paving steel bridge deck asphalt concrete pavement technology, conditional request is harsh unusually.Carry at driving dynamic load, wind, under the factor affecting such as temperature variation and earthquake, its high-temperature stability, antifatigue cracking behavior, the following to the steel bridge deck distortion, interlaminar bonding and perfect anti-drainage system etc. all have high requirement.Be laid immediately on the bridge deck pavement material on the orthotropic plate, its stressed and distortion is far beyond highway pavement or airstrip complexity, thereby the requirements at the higher level that its intensity, deformation stability, fatigue durability etc. have been proposed.
Old cement concrete pavement overlays asphalt concrete pavement (being called for short " changing black in vain "), key is how to prevent reflection crack, adopt and be interrupted half-open grating (English name Gap-Semi-Open-Graded,), be a kind of have absorption of stress and anti-vertical shearing effect, promptly have structural, again functional asphalt arranged.The advantage of being interrupted half-open grating and asphaltum with high viscosity is made up, toughness, elasticity and the adhesive capacity of asphalt have been improved, make structural stability, anti-fatigue ability, the low temperature extension ability of asphalt, qualitative leap has been arranged, delay effectively and reduce reflection crack.
To being used for the material of drainage asphalt pavement, " changing black in vain " road surface, steel structure bridge bituminous pavement, generally all to use asphaltum with high viscosity, and the preparation asphaltum with high viscosity must use properties-correcting agent, and SBS is used in recent years widely because of its good two-way modification performance (promptly changing the high temperature and the low-temperature performance of matrix pitch simultaneously).But because pitch is the extremely complicated organic high molecular compound of a kind of composition, its component of pitch that adopts the different crude oils refining to form obviously is different, even if with a kind of crude oil, because of the different gained bituminous component ratios of refining process also are not quite similar.So the consistency of SBS and road bitumen is not so good, the especially particular requirement of asphaltum with high viscosity, the influence that is subjected to consistency is bigger, make the road bitumen be used to prepare asphaltum with high viscosity must take into account with the consistency of SBS.
Summary of the invention
The purpose of this invention is to provide a kind of bituminous asphalt modifier with high viscosity and production method thereof of being soluble in.
