The performance of the mixture at low temperature was one of the most important factors to be considered to ensure its application in cold areas.
If increase the content of asphalt mixture, flexibility of the mixture rises and then show the same properties with hot mix asphalt (HMA).
Grading evaluation of recycling asphalt mixture Waste asphalt pavement can be recycled, but its performance is affected by factors of old milled material performance, the correct gradation designing and construction quality control.
The mixture milled need to be classified piled, evaluation content is mainly gradation , mechanical properties (crush value,acicular content), etc.
We can see that there are no significant difference for main properties between the three, and they all meet the requirements of the asphalt mixture lower layer, the emulsified asphalt milled mixture has the highest low-temperature bending tensile strain,but conventional asphalt mixture’s high temperature properties is best.

The structural change and properties of W6Mo5Cr4V2 alloy (M2 steel) inoculated by addition of rare earth (RE)-Ti were investigated.
Many attempts have been made to develop a process to minimize carbide segregation and increase the properties of M2 steel [6,7].
However, the studies are very limited about the effects of modification on the M2 steel properties, especially high temperature wears resistance and thermal fatigue resistance.
In this paper, the effect of RE-Ti composite modification on the structure and properties of M2 steel was studied.
This is because the morphology of carbides is the main factor affecting the properties of iron and steel.

Many processes and their relative factors are optimized using statistical techniques such as Taguchi method, Response Surface method (RSM), Grey Relational approach (GRA)etc.

The above studies help us in identifying the significant parameters in FS welding process that can affect the mechanical properties such as tensile strength and tensile elongation.
The mechanical clamps were used to clamp the plate in the worktable of the machine.
The range and respective units of each input and output factor differ.

In order to investigate the progressive failure process of brittle rock, the mechanical properties of red sandstone from southeast Shandong province were systemic studied.
Beside the stress concentration and dissipative effect, there are several other factors that have influence on the deformation and failure properties of rock.

Domestic and foreign scholars have had lots of studies on determination method and influencing factors of surface roughness.
It was an important way for reasonably developing plantation-Magnoliaceae glanca Blumes as a fast-growing timber specy in the south of China to strengthen comprehensive research of the nature and mechanical processing properties, therefore, many experts do a lot on this [8-9].
According to the above factors and determination of their levels, the orthogonal header design of the first sanding test L16(54) was shown in Tab.1.
To know whether three factors have significant influence on various parameters or not, the variance analysis is carried on.

According to the literature survey and test data report, the major factors which influence the reliability of 32m prestressed RPC girder in railway bridges are given in this paper.
Introduction RPC (Reactive Powder Concrete, RPC) is a new type of high performance composite material and has shown a wide applied prospect because of its good mechanical property and good durability [1-3].
At the same time, there exist many uncertain factors in structural engineering, so the statistical property of random parameters for the system including material characteristics and practical dimensions of the structure as well as loads will be changed.
The indeterminacy of the materials of structural members is mainly due to the quality of the material and the property variation of the material caused by the factors such as fabrication technology, load conditions, outline dimension and the environmental conditions etc.
