original asphalt 中文意思是什麼
original asphalt
解釋
天然瀝青-
By structural analysis and calculation for original highway structure without permeable layer, the critical modulus of base have been obtained which makes asphalt pavement fill different allowable stress criterion. by structural analysis and calculation for different highway structure with permeable layer, critical modulus of permeable base course are obtained to make asphalt pavement fill different allowable stress criterion. the paper also presents the tendency of structure response of different highway structure with drainable layers mainly depends on the thickness of asphalt pavement, the thickness and the critical modulus of permeable base
對于不設排水層的原路面結構，通過結構計算得出對應于不同的瀝青面層容許應力值時所需的基層臨界模量值；對于加設排水層的路面結構，通過結構計算得出對應于不同的瀝青面層容許應力值時所需的排水基層臨界模量值；加設排水層的路面結構的結構反應的變化趨勢主要取決于瀝青面層厚度、排水基層厚度和排水基層臨界模量值。 -
Whether original asphalt or bituminous mixture, test findings proved that homemade heavy traffic asphalt was as good as import asphalt
