Abstract: In order to fully master the opportunities and challenges of earthquake resistance and disaster
mitigation technology of highway engineering, the development of highway engineering's seismic technology
was reviewed, four main features, including the theory developed from static method to dynamic method
fortification concepts developed from simply seismic resistance to mitigation and isolation method, seismic
design method developed from strength criteria to performance-based design method, and fortification object
developed from one single highway structures to highway network and from earthquake disaster resistance to
multi-disaster resistance, were summarized. Based on the conditions in Wenchuan and Yushu earthquake
three current deficiencies of highway system, including weaker road network anti-seismic capacity
acquisition difficulty of earthquake disaster information of highway, and secondary disasters caused serious
loss, were put forward. The view that highway structures behaved well as a whole was put forward. Finally
five research areas that should be enhanced, including anti-seismic capacity of road network, road hazard
monitoring and assessment using remote sensing technology, prevention technology of secondary disasters after
earthquake, development of new technology and evaluation of existing techniques, emergency inspect
evaluation and emergency traffic.keeping techniques of highway structures, were suggested
Key words: road engineering; review and prospect; summary; earthquake resistance and disaster mitigation
