Aggregate:Gravel aggregate sizes were divided into 16~31.5mm,10~20mm,5~10mm and rock chips (<5mm),required the gravel was stronger,no impurities,high density,lower water absorption,grain composition should fit the design requirement;the crush value must meet the design requirement（≤30%）.
Maintenance Management after Molding.After each section of the cement stabilized gravel base rolled and the compactedness test qualified, using geotextile or concrete special maintenance film covered the whole surface.Then sprinkler showered keeping wet,the curing time should not be less than 7 days.spray-head of sprinkles should be fine spray type,high-pressure nozzle was forbidden to prevent damage to the structure,the number of sprinkling water on every day depend on theweather[5].Transportation should be closed during the curing time in order to avoid damage to the base.

Design parameters: trial-mix strength, cement type, cement content, aggregate type, grain composition, water consumption, sand ratio and so on.

This indicates a limited transport of Ge to the SiC surface through the growing SiC layer due to grain boundary diffusion.
Four measures are presented in this figure indicating root mean square (nm) amelioration in function of the number of incorporated Ge monolayer's.

Density is the weight per unit volume, and will increase with increasing atomic number in their subgroup[5].
This condition is due on hydriding process of the U-Zr alloy to form uranium hydride (U-ZrHx) from pieces of U-Zr ingot that does not irregular, then the hydrogen will be absorbed in the Zr metal to form ZrHx at the grain boundaries which lead ingots U-ZrHx become brittle and have irregular shapes.

Silica produced from rice husk has finer grains than mineral silica, is renewable, and contains relatively high silica, which is more than 80% [7].
In the FT-IR spectra, there is a shift in the characteristic absorption of silicate material at wave numbers 1620 cm-1, 779 cm-1, and 462 cm-1, which is assumed to be BTA in silicate.

This haze is probably related to the crystalline grain size and hopefully can be eliminated by changing the film deposition conditions.
The targeted goal for the number of quasi-reversible cyclic voltammograms (100,000 cycles) has been reached for our prepared PB systems deposited on Pt in the acidified solutions (pH ≅ 2).

Transition metal sulfides (TMS) form a very important group of materials exhibiting a number of interesting properties.
Nanocrystalline state is responsible of a high volume of grain boundary, and because this is a high-energy region, favors the surface phenomena, like catalytic activity.

All fatigue tests were run to the failure or separation of the specimens, and the corresponding cycling number was defined as low-cycle fatigue life Nf.
Meanwhile, the cyclic strain hardening behavior is also related to the obstructive effect of solute atoms, secondary phases, grain boundaries, phase boundaries and subgrain boundaries on dislocation motion.

HA/FA-coated ZrO2 implant and FAcoated ZrO2 implant show a micro-porous and rough coating structure with grain and pore size of several micrometers.

Therefore, after heat treatment, the number and the intensity of the slip-able interfacial region would be reduced, and the corresponding interfacial relaxation effects would need a higher activation energy under the vibration load.
In fact, many kinds of interface relaxation effects (e.g. the relaxation effects of the grain boundary[19] and phase interface[20], the interface relaxation of the metal-matrix composites[21] and some viscoelastic polymer composites[22], etc) were manifested in peaks form in a suitable environment.
