摘要
路面结构作为交通基础设施的重要组成部分,一直承受着交通荷载和外部环境因素的长期作用,其长期使用性能研究已经成为道路工程界的基础性工作.黑龙江省因地处我国寒冷地区,沥青路面的长期使用性能具有特殊性,因此在借鉴美国路面长期性能(LTPP)观测体系的基础上,结合我国和黑龙江省沥青路面主导病害特征,对黑龙省沥青路面长期使用性能有关的观测体系和技术指标进行了分析,以指导今后寒区沥青路面长期性能观测体系的建立.
Abstract
Pavement structure,as an important part of traffic infrastructure,has been subjected to the long-term effects of traffic load and external environmental factors,and its long-term performance research has become the basic work of road engineering.Hei-longjiang Province is located in the cold area of China,and the long-term service performance of asphalt pavement is special.There-fore,based on the long-term performance observation system of asphalt pavement(LTPP)in the United States,combined with the characteristics of asphalt pavement in Heilongjiang Province and China,the observation system and technical indicators related to the long-term service performance of asphalt pavement in Heilongjiang Province were analyzed.In order to guide the establishment of long-term performance observation system of asphalt pavement in cold area.
