Polymer modified asphalt prepared by the method and the preparation process for the preparation of compositions of asphalt and polymer, aggregates, road made from a polymer modified asphalt and aggregate have been prepared by the preparation method, were prepared by the preparation method roof sealed with polymer modified asphalt, a method of sealing a roof with polymer modified asphalt, road construction method, a method for recycling asphalt and recycled asphalt is manufactured by a method for recycling 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
