Key Technique on the Process Control for Construction of Hohhot circle Expressway Asphalt Pavements Bin Zhao1, 2,a Peiwen Hao1, b 1Highway School, Chang’an University, Xi’an City 710064, China 2 The Highway Engineering Bureau, Inner Mongolia, Hohhot 010051, China azhaobin219@sohu.com, bgl02@chd.edu.cn Keywords: Asphalt pavement, quality control, construction quality, technique ABSTRACT As vehicle flow on arterial highway in Inner Mongolia sharply increased, the originally designed natural increase rate of 8% per year has been exceeded on the vehicle flow in some sections.
However, there are still a few deficiencies in the quality of raw materials, gradation control of asphalt mixture and adjustment of equipment, etc.
Currently, the asphalt concrete mixing plant whose measuring device’s measurement accuracy of aggregate and powder can be controlled within ± 1% and asphalt’s measurement accuracy can be controlled within ± 0.5%, which has satisfied the requirements of measuring various materials, and considered a design for the compensation of “carry-over”.
As the result of experiences summing up, (the appropriate raw materials, correct target mixture ratio, enhancing mixing, transporting, paving and compaction) the other key processes is the prerequisite for producing qualified asphalt pavement.

Modal Analysis and Structure Optimization of a Printed Circuit Board NC Drilling Machine Jiawei Zhu1,a, Shide Xiao1,b, Jian Feng2,c, Xiangyin Meng1,d and Mingming Jiang1,e 1School of Mechanical Engineering, Southwest Jiaotong University, Cheng Du 610031, China 2Cheng Du HiCNC Equipment Co., Ltd, Cheng Du 610031, China azjwachen@sina.com, bsdxiao@home.swjtu.edu.cn, c 137816590@qq.com, dxymeng@home.swjtu.edu.cn, ejmm1698@gmail.com Keywords: NC drilling machine; Modal analysis; Structure optimization; Pro/Engineer; ANSYS.
As the key crafty equipment to PCB machining, the PCB NC drilling machine has a good development and a broad market.
To ensure that the imported model is whole, the parts of the drilling machine with different materials are bonded together and their respective borders are retained by the Glue Boolean-operation and the accuracy of the analysis is guaranteed.
Set the material constants.
The materials used are HT200, QT450-10, granite and GCr15.Then the model is meshed, a total of 164456 nodes and 703481 units are divided.

The materials used in high-temperature structures have design constraints which are in addition to those on materials used at, or near to, room temperature.
The addition of these constraints to those of low cost, strength, toughness, machinability, formability, weldability, and combinations of these, has led to the intensive development, over the past 50 years, of an extensive group of metallic materials: generally referred to as "high-temperature alloys".
The purpose of the present book is to provide chemical, metallurgical and materials scientists and engineers with up-to-date corrosion data pertinent to academic studies and industrial problems resulting from the effects of pure molten salt and ash/salt deposit environments. 
The book covers key aspects of corrosion reactions in molten deposits, and provides a wealth of engineering data to help in making a shortlist of candidate materials for high-temperature service under such conditions.
