加拿大国家工程研究院院士尔玛博士曾对中国沥青道路进行过考察,他惊异地发现,在中国92%的沥青路面平均寿命周期大约是7年～8年,而不是设计时期望的15年。2004年4月,交通部公路科学研究所沈金安研究员也发表文章,认为中国公路寿命约为7年～8年。因此,如何防止路面早期损坏,延长沥青路面寿命成为公路行业普遍关心的问题。路面早期损坏原因非常复杂,解决起来是一个系
Dr. Erma, a fellow of the National Institute of Engineering of Canada, once examined asphalt roads in China. He was surprised to find that the average life span of 92% of asphalt pavements in China is about 7 years to 8 years instead of 15 years as designed. In April 2004, Shen Jin’an, a researcher at the Highway Science Research Institute of the Ministry of Communications, also published an article saying that the life span of roads in China is about 7 years to 8 years. Therefore, how to prevent the early damage to the pavement and prolong the service life of asphalt pavement has become a common concern in the highway industry. The reasons for the early damage to the road is very complex, to solve it is a department
