新旧规程中沥青混合料理论最大相对密度测定的对比

关于沥青混合料理论最大相对密度的测定,由于原规程中对于真空度的要求不合理,新规程取消了真空度标准,统一采用负压标准,同时对试验步骤中的细节进行了修订,增加了修正试验。通过对新旧规程的对比分析,有助于更好地测量沥青混合料理论最大相对密度。

Contrast of Measure of Theoretical Maximum Relative Density of Asphalt Mixture in New and Old Criterions

Due to the requirement on vacuum degree in old criterion is illogical about the measure of theoretical maximum relative density of asphalt mixture,the new criterion replaces vacuum degree with negative pressure standard,edits the details of test steps,and adds the correction test.The contrastive analysis of new and old criterions helps to measure the theoretical maximum relative density of asphalt mixture better.
