Influence Analysis of Crack Depth and Position on Asphalt Pavement Structure with 3D Finite Element WANG Peng1,a 2 Cui Can2,b 1,2School of Water Conservancy and Environment Engineering, Zhengzhou University, Zhengzhou 450002, China awangp@zzu.edu.cn bcuican2008loves@126.com Keywords: highway engineering; surface-initiated cracking; asphalt pavement; finite element method; tire pattern; eccentric load Abstract: In recent years the research on Surface-initiated longitudinal cracking along wheelpath (or Top-Down cracking) is become a fresh hotspot in the field of pavement damage focused by international asphalt pavement engineering.Because the traditional load is the vertical surface load with uniform tire pressure, this loading is applied at only one position and no effort is made to distinguish between tire pattern.The traditional method can’t explain the mechanism of the top-down cracking.
With the increase of the cracks’ depth, the adverse influence of the shear stress becomes weaker and weaker.So the key of controlling the cracks in the surface layer is prevention.
So the key of controlling the cracks in the surface layer is prevention.

One is to judge the key factors during materials service.
In general, industrial system and civil engineering has normalized, explicit and fixed process and structure.
There are different relationships among components and equipments in one system and engineering.
This method can supply better training for domain researchers and engineers and obviously improve the efficiency of materials service case analysis.

Improvement of accelerated weathering test through physicochemical analysis for polymeric materials in building construction Teng-Chun Yang1,a 1Department and Institute of Materials Science & Engineering, National Taiwan University, Taipei 106, Taiwan atcyang.04@gmail.com Keywords: Accelerated weathering, Polymeric material, Physicochemical analysis, Durability, Degradation Introduction In civil engineering, the long-term service life of buildings as environmental measures is one of important performances being comparable to structure and fire safety, and it is demanded to improve durability of materials in building construction.
As part of building materials, polymeric materials become widespread in civil engineering because of taking advantage of excellent property, such as lightweight, high corrosion resistance, and good formability.
Reliability is an engineering discipline that should be applied throughout all stages of development and maintenance of the product in its life service.
Unfortunately, only very few researchers in civil engineering have being researching on macroscopic size (color, mechanical property etc.) of polymeric materials but barely discussing these microscopic size (physicochemical production ).
The other key point here is that these effect factors are not all absorbed by the material to transform the degradation phenomena.

of paper materials according to the children’s experience.
Result in the same performance, paper materials take 20% to 30% work of the wooden ones, thus high portability can be manifested by paper materials.
Financially thrifty.The financial advantage of paper material is another part of its green feature, the function of recycle and reuse of paper material is the key to its economical character.
On the other hand, paper materials are environmental friendly, economically green and convenient, these principles are key to choose the right materials when designing furniture.

Research on the Application of Limestone Powder in Concrete Engineering Shuangmei Cao School of Continuing Education, Henan Polytechnic Institute, 291# Gongnong Road, Nanyang City, Henan Province, PR China, 473009 caosm@126.com Key words: limestone powder, volume of limestone powder, concrete performance Abstract.
The company grasps the development trend of construction materials, studies the advanced experience such as “integrated pollution control and waste recycling” and “building energy-saving and green buildings” and actively explores new building materials.
In recent years, Shengxin New Building Materials Co. ltd. of Xixia has two problems need to be solved in the course of business.
So, in order to ensure the proper application of limestone powder in the concrete engineering, it should be based on the above test, then adjust the amount of water or additive, do repeated experiments, in order to get the proper asnd reasonable amount of the component materials which can meet the work requirements of concrete strength and workablity and give full play to role of limestone powder in concrete projects.
Developing new building materials, utilization of limestone scrap waste, makes the building material company find an effective way to substitute scarce raw materials of fly ash, achieving a revitalizing effect, lowering the cost of concrete projects, promoting energy saving, reducing consumption, low carbon and sustainable development.
