The influence of asphalt types on fiber asphalt mixture’s properties resistance to water damage Testing process and raw materials are consistent with the above mentioned, Dolanit ® AS fiber was choosed as an example, fiber content is 0.3% (this fibers content is weight ratio of fiber accout for the total fiber asphalt mixture, the same below), the mixture gradation was AC-16C type, the optimum asphalt content was taken as 4.8%, test results are as follows: Table 1 Test results of Marshall immersion test and freeze-thaw splitting Asphalt+Fiber(AC-16C) Marshall residual stability MS0 Freeze-thaw splitting residual strength ratio TSR MS1(KN) MS2(KN) MS0(%) RT1(MPa) RT2(MPa) TSR(%) Karamay 70# 10.11 8.60 85.26 1.03 0.84 83.23 Karamay 70#＋Dolanit AS 11.39 10.47 93.38 1.09 0.92 86.28 SBS-70# 12.43 10.82 88.31 1.10 0.94 86.28 SBS-70#＋Dolanit AS 13.76 12.80 94.40 1.15 1.02 90.34 From Table 1 to kown: ①Residual stability of asphalt mixture added Dolanit AS fiber is higher than
The influence of fiber types on fiber asphalt mixture’s properties resistance to water damage Testing process and raw materials is the same as above, for the six fiber AC-16C and no fiber AC-16C, the fiber content was taken 0.3%, the optimum asphalt content was taken 4.8%, test results are as follows: (a) (b) Fig. 1 Test results for asphalt mixture Marshall immersion and freeze-thaw splitting: (a) Karamay 70# conventional asphalt AC-16C (b) SBS-70 # modified asphalt AC-16C From the above table and figure to know: ①the use of fiber and the modified asphalt, fiber asphalt mixture’s MS0 and TSR are significantly higher than non-fiber and using ordinary asphalt, which mean the fiber and modified asphalt can improve mixtures’ performance resistance to water damage, so if the project allows, modified asphalt fiber mixture is proposed as pavement materials. ②For Karamay 70# ordinary asphalt mixture, fiber types sort

Effect of Post Weld Heat Treatment on the Interface Microstructure of Explosively Welded Titanium/Stainless Steel Composite clad Pezhman Farhadi Sartangi 1,a , Seiyed Ali Asghar Akbari Mousavi2,b 1,2 School of Metallurgy and Materials Engineering, School Colleges of Engineering, University of Tehran, Tehran - Iran, P.O.
The variations in the width of the intermetallic phases is governed by the diffusion of constituent elements, grain growth of parent materials, residual stress produced during welding process, thermal mismatching between the flyer and base materials during the heating process and softening of base metals due to annihilation of structural defect [3].

Electrolytical Obtaining of Ni-Mo Coatings with Polypyrrole Jolanta Niedbała, Antoni Budniok, Eugeniusz Łągiewka Institute of Materials Science, University of Silesia 40-007 Katowice, Bankowa 12, Poland e-mail 1 : jniedbal@us.edu.pl, e-mail 2 :budniok@us.edu.pl, e-mail 3 : lagiewka@us.edu.pl Keywords: electrolytic coatings, polypyrrole, Ni-Mo alloy Abstract.
Electrodeposition is unique in that it can be used for processing ceramics, polymers, metals, composites and hybrid materials [6-10].
Conductive polymers have been investigated for use as the electrode materials for a number of applications including rechargeable batteries, electrochemical sensors etc. [11-12].
Although polymers of pyrrole have been known for over 50 years, interest in these materials has greatly increased in the past decade because polypyrroles when doped intrinsically electrically conductive.
Taking into account the properties of Ni-Mo alloys and PPy the composite materials containing these two components is expected to exhibit very interesting properties.

The application of BMGs has been extended from structural parts such as commercial golf club to functional parts such as pressure sensor or hydrogen storage materials [2].
When certain extents of the crystallization preceed, both strength and ductility was increased compared with the as-cast BMG, implying that a selection of optimized heating conditions for BMG can control the strength and ductility, when BMG is considered as a precursor for nano-structured materials.

Introduction By applying the fundamental principles and methods of ecology to plan, design, construct, manage and operate, ecological campus is an environmental-friendly artificial ecosystem integrating functions like study, work, life, leisure together, in which forms a harmonious human-and-nature relation, reasonable layout structure of each species, high-quality environment, effective utilization of materials, energies and information [1].
For example, terraced landscape can be built utilizing gradually-up domain; natural spaces are molded utilizing natural materials, rural materials, and even local materials.
