The loess is widely distributed over the northwest of China, and the compacted loess is used as constructional materials in the construction of fill-dam, road, railway and airport runway etc.
Landfill or hazardous waste storage site also use compacted loess as encapsulation and cushion materials.

Experimental The copper particle with a purity of around 99.5% and ordinary commercially carbamide particle (CO(NH2)2) with a purity of around 99% were used as the parent materials, in which the carbamide has two kinds of particle size and shape.
The quasi-static compressive tests were carried out using a Sans/CMT4204 materials testing system at a crosshead speed of 2 mm/min.

Some developed countries began to make research and developed permeable pavement materials from the 1970 s.
After 1990's, it has become a general experience for the developed countries in urban construction by applying permeable materials to replace the traditional materials for building roads [1].

Table 1 The cutting conditions Name Cutting condition Work-piece material 45 carbon steel Hardness HB187 Tool material YT15Carbide the rotational speed of main shaft 460rpm Feed speed 0.15mm/r Cutting depth Cutting fluid 0.20mm Not used In the first experiment, the cutting force power spectrum measured is shown in Fig.3.
After unfolding the power spectrum in the lower frequency band, we discovery the main frequency constitution is decided by the rotational speed of the main shaft and the work-piece material, but the value approach zero when the frequency is larger than 240 Hz and can be ignored.
