Compaction Quality of Bitumen Mixtures Based on Ultrasonic Methods Tao XIE 1, 2, a, Yanjun QIU 2, b, Zezhong JIANG2, c and Bo LAN 3, d 1 College of Civil and Architecture Engineering, Guizhou University, Guiyang 550022, China 2 School of Civil Engineering, Southwest Jiaotong University, Chengdu 610031, China 3 Department of Transportation of Sichuan Province, Chengdu 610041, China a xie_tao96@163.com, bpublicqiu@163.com, c qmrjzz@yahoo.com.cn, dsclb2008@163.com Keywords: Bitumen mixture; Water damage; Porosity; Ultrasonic method.
Water damage of asphalt concrete pavements has been one of the major distresses in highway engineering.
Engineering experiences and research results indicate that this damage is due to the extortionate air voids of bitumen mixtures.
Ultrasonic is an excellent method for non-destructive testing used in various engineering fields.
This technology has been successfully used for evaluating concrete structures for many years, but has so far had only a very limited application in pavement engineering.

The maintenance and management of civil aero-engine require advanced monitor schemes to evaluate aero-engine health and condition in order to ensure safety of aircraft and increase life of aero-engine.
We require developing prognostic means to improve the engineers and maintainers knowledge of aero-engine performance in the upcoming flights.
If the details and behavior of these critical parameters for future flights is provided to maintainers and engineers it can help monitors the aero-engine condition.
Fig 5.The EGT_corr values prediction of aircraft ‘A’ by Kalman filter In addition, according to the engineering requirements the relative error can not beyond the ±0.3%.
This approach will therefore assist the maintainer and engineer in keeping track of those performance parameters behaviors in different flight modes.

Finally, two main specific engineering suggestions for avoiding this kind of crack on the upstream surface of super-high arch dam were given: (1) the value of checking water pressure should not exceed 0.4 MPa; (2) the flange of the water-stop structure near the upstream surface of dam should be changed toward the downstream.
Engineering Recommendations for Prevention and Control of Cracks Sealing Flange in Vertical Direction.
The engineering recommendations for preventing and controlling of cracks on the upstream surface of super-high arch dam were given as follow: (1) water pressure of checking should not exceed 0.4MPa; (2) the flange of the water-stop structure near the upstream surface of dam should be changed toward the downstream.
This work has some guiding significance for in-depth understanding the crack mechanism of the 300m super-high arch dam, and for taking the engineering counter-measures to avoid this kind of crack.
