Nowadays, there are numerous kinds of road base materials.
Therefore the selection of road base materials becomes one of the most important steps in highway construction.
Therefore, their life cycle cost model was over simplified in term of the decision and selection of the road base materials.
Therefore it was suitable for the selection of the road base materials with multiple influence factors.

The Thinking on Multiphase Materials Jingkun Guo*, Huamin Kou, Yubai Pan State Key Lab of High Performances Ceramics and Superfine Microstructure Shanghai Institute of Ceramics, Chinese Academy of Sciences 1295 Ding-Xi Road, Shanghai, 200050, China *jkguo@sunm.shcnc.ac.cn Keywords: Multiphase materials, ceramics, alumina, core-shell Abstract.The main problems for multiphase materials are the even mixing and the bonding or reacting among two or more phases, as well as the states of their grain boundaries.
Even mixing Even mixing between each other material is important for multiphase materials.
Reactions for multiphase materials It's required that no reactions occurs among each phases for multiphase materials.
Therefore, multiphase materials are a good target for the material designing.

FEM of ECDM Process on Semi Conducting Materials Lijo Paula*, P.V.
The scope of ECDM in micro machining of semiconducting materials is still found to be promising challenge for researchers.
Many researchers have carried out the modeling of ECDM for various engineering materials.
From the literature review it is found that very less work has been reported in FEM of ECDM in semi conducting materials.
An isothermal curve is generated with respect to melting point of the workpiece materials.
