国内外硬质道路沥青标准比较分析

Comparative Analysis on Hard Paving Asphalt Standard Home and Aboard

硬质道路沥青具有针入度低、软化点高的特点,高溫性能优良,可以用来提高路面的抗高温车辙能力,延长路面的使用寿命。近年来,随着国内高性能长寿命路面概念的提出及推广,硬质道路沥青是具有较高性价比的可选材料之一,为了进一步推广硬质道路沥青在国内的生产加工及其在道路工程中的应用,介绍了国内外硬质道路沥青的发展和相关产品标准,对比研究、分析了国内最新硬质道路沥青标准的特点,为沥青生产企业组织相关硬质道路沥青新产品的生产提供参考,以便能够生产满足道路行业建设需要的高质量沥青产品。

Relevant studies show that the hard paving asphalt has excellent high temperature perform-ance,with the characteristics of lower penetration and higher sofening point,which can be used to improve the anti-ruting performance and prolong pavement service life.In recent years,with the proposing and pro-moting of high-performance and long-life pavement concept in China,hard paving asphalt is one of the ma-terials with?high cost performance.In order to further promote hard paving asphalt production in domestic refineries and its application in road engineering,through introducing the development of hard paving asphalt and the comparative research of relevant product standard home and abroad,analyzing the characteristics of domestic latest hard paving asphalt standard,to provides reference for asphalt production enterprises in produ-cing hard paving asphalt relevant products,so as to meet the needs of road industry.
