However, because of material and fabrication of WM, the relation between WM’s coils resistance R and electric current I is more complex, which can be expressed by Eq. 1 [7, 8].
At present, a WM of SHMFF is being constructed in high magnetic field laboratory of Chinese academy of science.

Determation of material performance.The material performance datas needed during fatigue assessment are the coefficents and in Eq.1,also the threshold stress intensity factor .These coefficents can be got through special fatigue crack propagation rate test.According to the test data, using the least squares regression,we can get and .
Fatigue assessment program develop and verify of surface defects According to the surface defect assessment methods provided in the previous chapter, a special program is developed with Fortran language.The program can be used to calculate the fatigue crack propagation and assess the lifetime.Once the material properties , the range of stress and the initial size of defect are known,the initial amplitude of stress intensity factor can be calculated through this program, then we can determine that whether the fatigue asseement should be necessary.As to the defect need be assessed, if the fatigue cycle number is known,the final size of the defect can be calculated after the cycle,then the safty assessment can be conducted.Besides,if without the fatigue cycle life information, we can set the crack deepth,length or amplitude of stress intensity factor be assessment parameters,thus providing reasonable technical data for the determination of repair cycle.

Abstract: Establish the mechanical model of asphalt pavement low-temperature cracking, analysis the factors leading to cracking.
The main factor of resistance to low-temperature shrinkage cracking refers to unit area cracking energy accumulated along the thickness direction of asphalt surface layer: In the formula: --tensile strength of asphalt mixture in the temperature of Ti; --limit tensile deformability of asphalt mixture in the temperature of Ti; h--thickness of asphalt layer; Formula shows that: ability of resistance to low-temperature cracking is not only related to factors of material (tensile strength and limit tensile deformability of asphalt mixture) but also related to the asphalt layer thickness h and its structure factors such as combination.
The deposited energy that leads to shrinkage cracking is represented as: In the formula: аi:Temperature shrinkage coefficient of asphalt mixture; B,L:Respectively represent the width of the pavement and crack spacing; σ(T0,hi):temperature stress at hi thickness of asphalt pavement ; ΔT(T0,hi):difference in temperature leading to temperature stress Formula shows that: the factors that lead to crack are not only related to factors of materials such as temperature shrinkage coefficient of asphalt mixture and temperature stress but also related to other factors such as structure combination and temperature distribution.
