| Abstract: | Through the investigation of natural grit used as the material of the main arterial highway in Tibet,the region research on natural grit in Tibet has been carried out,which is mainly based on the climate type.According to the gradation composition of natural grit at various districts in Tibet,the thickness of the natural grit in Tibet has been analyzed by the method of characteristic aperture passing rate and fineness modulus.Meanwhile,the representative gradation of natural grit in Tibet is proposed. |

| Keywords: | Tibet natural grit representative gradation characteristic aperture fineness modulus |
