沥青路面结构内部温湿度监测技术应用

Pavement structure service environment monitoring technology based on temperature and humidity and big data platform

道路在服役过程中的环境和荷载双重因素作用是导致路面结构破坏的主要原因,而外界环境中的温湿度对路面结构影响最显著,因此道路长期性能监测成为道路维护中的重点工作。采用温、湿度传感器实时监测沥青道路服役过程中路基路面温湿度变化,结果发现温、湿度传感器可以较为精确地监测道路温湿度场变化特征,为道路养护提供数据支撑。

The dual factors of environment and load in the service process of the road are the main reasons for pavement structural damage,and the temperature and humidity in the external environment have the most significant impact on the pavement structure,so the monitoring of road long-term performance will become the key work in road maintenance,and this paper uses temperature and humidity sensors to monitor the temperature and humidity changes of the roadbed pavement during asphalt road service in real time.It is found that the temperature and humidity sensor can accurately monitor the change characteristics of road temperature and humidity field,and provide data support for road maintenance.
