Key words: Coal Gangue, Asphalt Mixture, Mix Design, Pavement Performance
Abstract.
As a constructing material, coal gangue has been used in brick-making,cement-production and cement concrete as well as road base.
As a kind of visco-elastic material, asphalt mix is time and temperature dependent.
Acknowledgements The authors appreciate the financial support of the Beijing Municipal Science & Technology Commission for the research program of “Research on the Utilization of Mining Wastes”(D08040300200801).

Introduction
With the development of science and technology in the manufacturing domain, integration of different systems gets more and more recognition.
This includes material, surface condition and geometric data.
Each workpiece has only one surface condition and one material. 3)Executables : To make things happen Executable is the base entity of all executable objects.

amurakami.t@aist.go.jp, bk.matsuzaki@aist.go.jp
Keywords: tribology, friction, wear, intermetallic compound, Fe7Mo6, spark plasma sintering.
Because it is well known that MoO3 is a low friction material, the Fe7Mo6-based alloy/Al2O3 tribopairs exhibited low friction coefficients at 873 K in air and at 298K in water.
More work will be needed to obtain low friction materials at high temperatures in air and at 298 K in water.

Many lightweight materials have been used for vehicle weight reduction.
Let’s take a closer view, as to what materials were used and how did we go about using them for good results.
This provides enough adhesion to hold the materials in place.
However, when using less permeable materials or higher viscosity resins, this number may be reduced.
