Abstract:

In recent years, technological innovation plays a more and more important role in the development of various industries. With the arrival of a new era of knowledge economy, patents have been recognized as an important scientific index to measure the ability of technological innovation. A large number of petroleum asphalt pavement in China is seriously damaged, and various unconventional problems have appeared one after another,in order to better understand the research status and trend of modified petroleum asphalt pavement, this review summarizes and analyzes the characteristics of domestic modified petroleum asphalt patent technology route around the patent achievements published in recent years and combined with literature reports. The results show that the modifier will be more environmentally friendly, and the effect of compound modification of various modifiers is good. On the basis of physical preparation and appropriate chemical stabilization method, it is necessary to obtain road modified petroleum asphalt with excellent performance. On this basis, the research emphasis and direction of modified petroleum asphalt are discussed, and the material will tend to emulsify high viscosity asphalt, The function will tend to compound and the construction machinery will be miniaturized in order to provide reference for the research and application of modified petroleum asphalt in China.

摘要：

近年来，技术创新在各个行业的发展中发挥着越来越重要的作用，随着知识经济新时代的到来，专利已经被公认为是衡量技术创新能力的一个重要科学指标。我国大量的石油沥青路面破损严重，各种非常规的问题相继出现，为了更好地了解改性石油沥青路用发展的研究现状和趋势，本文围绕近年来公开的专利成果并结合文献报道，归纳总结并分析了国内改性石油沥青专利技术路线的特点，结果说明了其改性剂必将更加环保，多种改性剂复合改性的效果良好，并提出了在物理方法制备的基础上，配合适当的化学稳定法，必能得到性能优异的路用改性石油沥青，最后对改性石油沥青的研究重点和方向进行了探讨，认为其材料会趋向于乳化高黏沥青，功能会趋向于复合化，施工机械小型化。旨在为国内改性石油沥青的研究和应用提供参考。
