Description
Technical Field
The invention relates to the technical field of modified asphalt, in particular to U-pave special modified asphalt, a preparation method and application thereof.
Background
The highway construction pace in China is accelerated, the maintenance task of roads is intensified, and China gradually changes from a construction stage to a maintenance stage. Because heavy-duty vehicles are more in road vehicles in China and heavy traffic phenomena are common, the early damage of the asphalt pavement is serious under the condition of heavy traffic. How to effectively improve the anti-deformation capability of the asphalt mixture and the binding power between the binder and the aggregate becomes the key to solve the problem of pavement diseases. Meanwhile, as the highway maintenance needs to open traffic quickly, the highway is maintained quickly, and the method has important significance for maintaining the service performance of the road surface, ensuring the smoothness of the highway and prolonging the service life of the road surface.
The traditional method for curing the diseases of the expressway comprises a Novachip ultrathin wearing layer, milling and paving, in-situ heat regeneration, micro surfacing, finishing and the like. However, these curing methods have limitations. For example, the traditional disposal mode of milling 4cm and paving the SMA13 mixture cannot fully utilize the original modified asphalt surface layer mixture, and the adhesive layer damage condition is serious in the construction process; the construction quality of in-situ heat regeneration is difficult to control, and the site variability is large; the micro-surfacing road has high noise, and is not suitable for sections with track depth exceeding 10mm, and the like. In the conventional maintenance of diseases such as ruts of highways, the Novachip ultrathin wearing layer technology is used more and is one of the solutions, but the technology needs to be constructed by specific paving equipment, so that the technical limitation condition is harsh. Meanwhile, in the construction process, consideration and pre-control need to be carried out on each detail of raw material selection, mix proportion design and construction control, and the cost is high.
The research on ultra-thin cover surfaces in China is relatively few, and a composite multi-effect warm mixing agent, a preparation method and application thereof (CN107501689A) are reported to be prepared in an additive mode. The auxiliary additive prepared by the method is a high molecular compound similar to a surfactant, the preparation conditions are relatively mild, the reaction is carried out under normal pressure, and the reaction conditions are relatively easy to control. And the prepared additive is liquid and is better compatible with asphalt when being added into the asphalt. And the requirement on preparation equipment is not high, and the asphalt can be directly added into asphalt for use without secondary processing. Therefore, the preparation method is simple. The chemical reaction type SBS modified asphalt thermal storage stabilizer and the preparation method (CN 104479169A) of the chemical reaction type SBS modified asphalt thermal storage stabilizer are only reported in a comparison document, the SBS modified asphalt thermal storage stabilizer is not applied to an ultrathin cover surface, and the additive does not contain an auxiliary agent for improving the high-temperature performance according to the judgment of the high-temperature performance of an asphalt mixture. Therefore, it cannot be used for 2.5cm ultra-thin overlay. Therefore, the technical content similar to the patent is not reported.
The existing common surface layer mixture has high modulus and lacks good low-temperature flexibility, so that the modulus of the surface layer is not matched with the original pavement, and the structure is not crack-resistant. Therefore, in order to improve the utilization efficiency of the old pavement structure and exert the performance of the modified asphalt mixture on the upper layer, the milling depth of the old pavement needs to be reduced for ultrathin pavement; in order to comprehensively improve the rutting resistance, crack resistance and skid resistance of the asphalt pavement, a high-performance pavement layer material is needed; in order to improve the workability of ultrathin pavement construction, save energy, reduce emission and solve the problem of quick cooling of an ultrathin pavement layer, a warm-mixing construction technology needs to be comprehensively utilized.
Based on the practical experience and professional knowledge of designing and manufacturing the product for many years, the inventor actively carries out research and innovation by matching with the application of the theory, and aims to create the U-bag special modified asphalt, the preparation method and the application so as to have higher practicability. After continuous research and design and repeated trial production and improvement, the invention with practical value is finally created.
