沥青路面再生技术应用障碍分析与对策——以江苏扬州地区公路沥青路面再生利用为例

Analysis and Countermeasures of Asphalt Pavement Regeneration Technology Application Obstacles——Take the Recycling of Highway Asphalt Pavement in Jiangsu Yangzhou Area as an Example

为破解沥青再生技术在现实应用中的障碍,以扬州地区公路沥青路面再生利用为例,对近3年扬州地区公路废旧沥青产生的数量、废旧道路沥青再生利用率以及沥青再生技术的应用情况进行了调查,对沥青路面再生利用在技术、科研、资金、社会大环境等方面存在的障碍进行了分析,在相关文献研究以及工程实践的基础上,对沥青路面再生利用障碍从制度完善、科研投入、技术革新等方面提出了应对措施。

Abstract： In order to solve the obstacles of asphalt recycling technology in practical application,taking the recycling of highway asphalt pavement in Yangzhou area as an example,in recent three years,the amount of highway waste asphalt produced in Yangzhou area,the recycling rate of waste road asphalt and the application of asphalt recycling technology were investigated.The obstacles of asphalt pavement recycling in technology,scientific research,capital and social environment are analyzed. On the basis of the relevant literature research and engineering practice,the paper puts forward some countermeasures for the asphalt pavement recycling obstacles from the aspects of system improvement,scientific research input and technical innovation.
