Road made from the aggregate and polymer modified asphalt prepared polymer modified asphalts were prepared by the method of preparation and method of preparing the composition of the polymer and asphalt, aggregate, the method of preparation, was prepared by the method of preparation recycling asphalt that has been produced by the method to recycle asphalt and how to recycle method of sealing with polymer modified asphalt roof, the roof is sealed with a polymer modified asphalt, road construction method, the asphalt

摘要

Improved method of mixing of the polymer composition and [challenge] asphalt are known, elements necessary for commercial success, available without the need to mix simple treatment method, the cost method of reducing contents, expensive fragment how to use the asphalt off parts such the like. In addition, the asphalt composition must meet the environmental and physical properties of the government. An object of the present invention lies in reducing or maintaining the cost of the crosslinking agent and polymer to improve the properties of the composition of asphalt and polymer without any element to sacrifice, is added to the asphalt. [SOLUTION] Therefore, the mixture of polymer and asphalt crosslinked with accelerators and other crosslinking agents and / or sulfur as well as performing the processing of inorganic acids, to improve the high temperature region properties of polymer modified asphalt. This acid, I added to the asphalt prior to the addition of cross-linking agent. [Selection] Figure Figure 1
