Introduction Bridge structural health monitoring (SHM) is one of the most popular research areas in the field of civil engineering lately.
With the development of bridge Structural Health Monitoring (SHM) technique and digital city concept, the Cluster Health Monitoring (CHM) system for urban bridges, simultaneously real-time monitoring numerous bridges in the city rather than separately monitoring single one bridge, has been come into engineering practice.

Studying recycling old asphalt mixture solves the problem of environmental pollution and recycles the waste materials and saves a lot of resources, providing technical reference for recycling old asphalt mixture as pavement recycled materials in the applications of actual engineering. 1 Experimental method 1.1 Test instruments The main instruments of the experiment are as follows: The computer automatic concrete pressure testing machine, whose model is STYE-3000C, made in Zhejiang civil engineering instruments manufacturing co., ltd., is used to measure the compressive strength of the asphalt mixture .
Microcomputer controlled electro-hydraulic servo universal testing machine, whose model is WAW-1000B, made in Zhejiang civil engineering instruments manufacturing co., ltd., is used to determine the tensile strength and bending strength of asphalt mixture. 1.2 Experimental materials Recycled asphalt pavement materials (RAP) for the test are taken from the Yangquan Jiujie to Potou sections of Taijiu expressway, broken by milling.
The results have important guiding significance to the application in practical engineering of old materials recycling.

Fig.1 Main bridge of Yu-Cheng Bridge under construction In the original design of Yu-Cheng Bridge, engineers used NC in the whole bridge because NC had long been considered as an efficient construction material.
However, the service life of structures with NC has always been one of the most important problems in construction field and the defects of NC in construction applications, its weak durability particularly, have plagued civil engineers for a long time.
