Assuming that a linearly elastic material,small strains and displacements and a time harmonic exp(-iωt) dependence but without considering external traction,variational model of elastodynamics[11] is shown as: ∫vδέTбdV－ω²∫vδũTρũdV=0 (11) for any kinematically admissible trial displacement field δũ=[δur,δuθ,δus]T.The ρ is density and ∫v·dV is volume integration of the element.
Both two springs specimen for experiment of ultrasonic guided waves testing have approximately 5.83(or 35/6 ) loops,and one has 1mm deep notch in the middle length and the other has not.Other parameters of the spring specimen are listed on table 1 and table 2,which include size parameter and material parameter respectively.

Introduction Ergonomics in an industrial environment is the science of fitting tasks to the workers to effect industrial improvements.
Ergonomics concepts and knowledge were applied to improve this material handling process via the utilisation of new equipment to ease their tasks.
Upon further discussion with the technical personnel, a simple structure made from both new and scrap material was built (Fig.3) for testing use in the workstation.

The main raw material is limestone aggregate and SBSI-D modified asphalt.
Production mix design According to the target mix design, the cold material feeding speed and speed ratio.
Mixture paved by machine should not be repeated artificial dressing except that local shortage of material; obvious roughness of surface; the local mixture segregation, obvious drag marks caused by paver.
