当前,我国高速公路设计寿命为15年,那么能否达到30至50年?以长寿命路面为代表,我国如何加快构建具有中国特色的、体现世界领先水平的第五代道路技术体系,是摆在路面科学工作者面前的一项重要课题。


10月17日至18日,在京召开的香山科学会议第S54次学术讨论会上,数十位多学科跨领域的专家学者齐聚一堂,以中国长寿命路面关键科学问题及技术前沿为主题,展开交流研讨、碰撞智慧火花。


与会专家认为,当前我国路面工程技术正处在跨越式引领发展阶段,路面学科应坚持问题导向和需求导向,以建设中国长寿命路面为总体目标,进一步强化基础研究,加强路面学科的平台建设,推动我国路面工程向耐久、绿色、智能化高质量发展。

站在历史的新起点,面向更高的要求,我国公路路面技术还有不足。交通运输部副部长刘小明指出,路面使用寿命偏短、原创基础理论严重缺乏、应用研究多基础性研究少、专业人才多复合型人才少,成为我国路面技术存在的突出短板。

长寿命路面五问


1.为何建设长寿路面?

当代道路技术正从以高速公路为代表的“第四代”道路,向以耐久、绿色、智能为特征的“第五代”智能道路转型发展。满足人类和社会发展需求,提升路面使用寿命,研发长寿命路面技术,应是当代路面科技发展的核心目标。建设长寿命路面,是提高路面使用性能的优良率和路网通行能力最有效的途径,可以推动节约社会资源、保护自然环境等“绿色”目标的实现,同时也为智能交通体系的建设提供一个可靠、耐用的基础平台。


2.长寿命路面的概念什么时候提出的?

   

1997年,英国NUNN教授从全寿命周期费用最小的观点,首次明确提出长寿命路面的概念。至此,长寿命路面设计技术的研发成为主旋律。

   

3.路面寿命的内涵是什么?

   

一般来说,路面寿命的内涵包含两个方面:一个是设计基准期,即设计“期望”寿命,一个是实际的使用寿命。

   

4.长寿命路面的技术体系包括哪些方面?

   

长寿命路面的技术体系包括:路面结构设计的新理论与新方法,能改善路面使用性能、提高路面使用寿命的新材料研发、设计与制备技术,路面结构与材料路用性能的感知技术与试验检测技术,路面施工与质量控制技术,路面养护管理及大中修技术,以及相关的标准规范。

5.通过研究,路面使用寿命将达到多少年?

   

从上世纪末,世界各国竞相开展长寿命路面的研究,希望实现公路路面的使用寿命提高到30年和50年的分阶段目标。
