Research in Analysis of Asphalt Pavement Performance Evaluation based on PSO-SVM Ke-zhen Yan1,2,a, Zou Zhang2,b 1Hi-tech Laboratory for Mountain Road Construction and Maintenance, Chongqing Jiaotong University, Chongqing ,400074, China 2College of civil engineering, Hunan University, Changsha,410082, China ayankz2004@163.com, bzhanghnu@163.com Keywords: pavement performance evaluation, PCI, SVM, PSO, pavement Abstract.
In road engineering, PCI, SSI, SRI and IRI were selected as the asphalt pavement performance evaluation indexes, but it is difficult to get pavement condition index.
Engineering application After investigating and testing a highway asphalt pavement in Eastern China, the four asphalt pavement performance indexes (PCI, SSI, IRI, SRI) was collected.

The Mechanic Analysis and Construction Method on Damaged Beam of External Prestressing Reinforcement Jianhua Gao The Department of Civil Engineering, Sichuan College of Architectural Technology, Deyang, Sichuan, 618000, China Jijing1977@163.com Keywords: Reinforcement Reconstruction, Carbon Fiber, Internal prestressing strengthening, External Prestressing Strengthening.
In order to investigate the feasibility of reinforcement transformation schemes for actual engineering, Combined with the characteristics of the project, the reinforcement transformation designs of the roof beams is carried out, three kinds of reinforcement transformation design schemes are put forward, they are carbon fiber reinforced polymer strengthening, internal prestressing strengthening and external prestressing strengthening.
Carbon fiber reinforced polymer is widely used in the concrete structure reinforcement and reconstruction engineering, and it is one of the effective methods to improve the bearing capacity of concrete members and to improve the function of normal use.
