The materials’ properties of soil and pile are different, what’s more, the soil can not withstand tensile stress or the tensile performance is poor.
The properties of the pile and soil materials.
The properties of the pile and soil materials are showed in the Table 1 and Table 2.

If the die life could be generally enhanced tens of thousands times, this advanced forming technology can be used not only in the low melting point alloy forming, but also will make a spurt of progress in the iron and steel materials auto parts manufacturing industrial application.
The peak of the temperature was the highest, and overstepped the mold material operating temperature upper limit.
This also means that die temperature for iron and steel materials in liquid die forging changes rapidly, and the die is more susceptible to thermal fatigue damage.
So the research on die life is more important for iron and steel materials in liquid die forging.

Materials and experiments 2.1.
Firstly, polymer material(such as PEG, epoxy resin) and nanometer materials were mixed at 80℃ for 15mins.
Then, some coupling agent(like silane) was added to the above-mentioned materials, 80℃ for 15min.
These conditions cannot meet the requirement of the paving materials.
