摘要
对国内外30号硬质沥青的研究和应用现状进行了概述,通过研究者的研究结果表明,低针入度的硬质沥青具有优异的高温性能和良好的低温性能,能够有效地增强路面结构、克服沥青路面的车辙损坏、提高路面寿命,具有广阔的应用前景。针对我国夏热冬冷或冬温气候分区较广阔以及路面重载、超载较多的特点,应加快硬质沥青产品开发和路面应用研究。
The research results of No. 30 hard asphalt at home and abroad have shown that the low penetration hard asphalt has excellent high temperature performance and good low temperature performance, it can effectively enhance pavement structure, overcome the rutting damage, and improve pavement life. Therefore, hard asphalt has the broad prospective application. According to characteristics of large range on temperature and climate differences in China, frequent heavy load and overload of pavement, the development and pavement application of hard asphalt should be accelerated.
