Mechanical and Economic Analysis of Asphalt Pavement Structure on Mix Base PENG Hong-wei1,a , OU Bi-Feng2,b 1Hunan Communication Science Research Institute,Changsha,China 2Hunan ChangXiang Expressway,Changsha,China a5404317@qq.com b395924577@qq.com Keywords: Road Engineering; Mix Base; Asphalt Pavement; Mechanical Analysis Abstract: Based on asphalt pavement design theory and criterions in China, five asphalt structures are put out, including three mix base pavement structures, one typical semi-rigid base pavement structure and one typical flexible base pavement structure.
But the material is not same and the price for different material is different, so the cost performance for each structure is different too.

It requires a long period and a large amount of rocks for the effective displacement to reinforce the dam, but the dangerous case occurs suddenly and frequently, and depletes the human, material and financial resources causing huge economic losses.
Because they have better overall stability, which could form a steeper slope and reduce material consumption; (5) The tetrahedron-like concrete penetrating frame groups have stronger anti-erosion ability and self-protection ability.

In recent years, carbon nanotube (CNT) has attracted considerable research attention because of its unique electronic, structural, mechanical and electromechanical properties, making it a novel electrode material in electrochemistry for the analysis of various important electroactive substances, such as phenolic compounds [6].
(Sichuan, Chinese Academy of Science). 2.2 Preparation of the modified electrodes The glassy carbon electrode (GCE, 3 mm-diameter) was firstly polished with 0.3 and 0.05 μm alumina slurry on a polishing cloth followed by rinsing thoroughly with double distilled water, successively sonicated in 1:1 nitric acid, ethanol and double distilled water for 3 min after each polishing, respectively, finally activated by scanning at -1.2 to 2.0 V for 5 cycles and dried at room temperature.1.5 g of MWCNTs were dispersed in 6 mol·L-1 HCl.
When MWCNTs was used as an electrode material, the surface area of the electrode was increased.

Cold forming is a method of shaping hard and brittle metallic materials at room temperature using pressure.
This machining method not only offers advantages such as a wide range of applicable workpiece materials, no restrictions on material mechanical properties, high processing efficiency, simplicity of operation, and low cost, but also produces micro-column arrays with no residual stress, no recast layer, high accuracy, and excellent structural performance [17,18].
Experimental materials and parameters.
This is because during the electrolytic alloying of steel materials, if the current density is too low, the electrochemical reaction produces oxygen, which forms a modified layer (adherent) on the machining surface.

Introduction Industrial Engineering (Industrial Engineering, IE for short) is a discipline to design, improve, and set the integrated system consisting of personnel, materials, equipments, energy and information [1-3].
In addition, IEBOK should also include the knowledge that has been included by other disciplines and majors but still generally accepted by IE staffs, such as the knowledge of sociology, psychology, and management science, etc.
The system concept is a way of thinking based on the system concept and philosophy revealed by the system science, which is the dominant ideology of system analysis to imperceptibly regulate people's work behaviors.
