Due to the fact that the stress and deformation undergone by deck pavement material that is paved directly on orthotropic steel plates on bridges are far more complicated than those applied in the case of highway pavement, stricter standards are required on the deck pavement material in terms of its stability under high temperature, fatigue and crack resistance performance, suitability for deformation of the surface plates of steel bridges and interlayer bonding.
The steel box girder on the main span is paved with epoxy asphalt concrete and is constructed by thick wearing layer of 25mm, bonding material of leveling layer, thick leveling layer of 25mm and bonding material for the steel deck pavement.
The test is done under two levels of temperature: 60 and 70, and other materials are also used as comparison.
The employed test equipment is MTS810 Servo Hydraulic Material Test System.

It is calculated that the maximum stress for the column of the heavy planer type milling machine with 10-level cavities under the action of cutting force is 28.16 MP, far smaller than the permissible stress of 170 MP for materials.
Only for one column of the heavy planer type milling machine, 36t metal materials can be saved.

Biocompatible Microcapsule of Carboxymethyl Cellulose/Chitosan as Drug Carrier WANG Fei-juna, LU Fang-shub, CUI Mengc, SHAO Zi-qiangd School of Materials Science & Engineering, Beijing Institute of Technology, Beijing 100081, P.R.China awangfj@bit.edu.cn, blufangshu@bit.edu.cn,cxiaoshou0502@163.com, dshaoziqiang@263.net Keywords: layer-by-layer self-assembling; carboxymethyl cellulose; chitosan; biocompatible; microcapsule; drug delivery Abstract: The biocompatible microcapsule of carboxymethyl cellulose/chitosan is obtained through two steps: firstly, carboxymethyl cellulose (CMC) and chitosan (CS) layer-by-layer self-assemble onto melamine formaldehyde (MF) microspheres; secondly, MF template is removed.
Nowadays, the major direction in the study of LbL technique is how to use it construct nano-structure ordered functional system and then develop new type nano-structure materials with good performance [7-8].
Experimental Section Materials Chitosan (CS, deacetylation degree>85%); carboxymethylcellulose sodium(CMC，made in our lab, DS 1.16, testing by the titration and NMR); chitosan was labeled with FITC (fluorescein isothiocyanate) for the UV-vis test; melamine, formaldehyde solution(37%~40%), sodium chloride, acetic acid, hydrochloric acid, poly(vinyl alcohol)(PVA, molecular weight 1750±50) were purchased; tetracycline ( Bioszune life sciences dep.).
Multilayer fabrication on quartz slides Till now, there was no specific research about the CMC and CS as the LbL assembling materials.

The fatigue crack initiation behaviour of the Al layers in composite metallic laminates can, therefore, be compared to the behaviour of monolithic Al if the actual stress conditions at the notched edge are equivalent for both materials.
