Description of the Invention (i) The present invention is an order, calendar composition, its preparation method, and its use in asphalt mixtures for road applications. As a binder in the road asphalt mixture, the same system has been continuously developed to meet the increasing demand of Kushiro road building materials for its efficiency. Generally, it shows good performance in road asphalt. However, the increasing mass load of people ’makes many roads premature to wear due to wheel tracks and cracks on the surface. Cracks are a serious disadvantage in asphalt roads because cracks allow water to reach lower levels of the road surface, which causes rapid deterioration and the need for premature repairs. Increasing the amount of asphalt in the asphalt, or using more specialized grades, such as Shi Qing, can improve the crack resistance of asphalt at low temperatures, but because the milk mouth is really soft, it will increase the excessive rotation at higher temperatures. Trace of danger. Conversely, the resistance generated by the wheel tracks can be increased at the expense of crack resistance, by reducing the amount of asphalt in the asphalt mixture, or by using harder grades of asphalt, because the mixture becomes less flexible. Based on the above reasons, the development of a harder asphalt composition to meet the needs of today's crack resistance, that is, the development of an azure composition that can simultaneously have good low temperature performance and good resistance to wheel track formation is obviously very The favorable 0, low temperature properties of known asphalts can be improved by mixing them with polymers. However, when such improvements are applied to hard bitumen, incompatibilities between bitumen and polymers are often found, resulting in little or no improvement in low temperature properties and poor aging behavior. In addition, it is known that bitumen of industrial grade and roofing material can be prepared by performing a conventional blowing method on the asphalt / polymer mixture.
