Semi-rigidity base materials have been widely used in China for a long period; and now cement stabilized aggregates is the main one. Low dosage cement stabilized aggregates road base is similar with it but the cement dosage is less
so the performance of economy and preventing cracking become better. Firstly
how the percentage of various dimension granule influent the intensity of this material is analyzed secondly
the curve about the relation of intensity and dosage of cement is made
which is based on the same percentage of various aggregates; at last
through comparing the CBR and intensity of various dosage cement stabilized aggregates
the probability of using low dosage cement stabilized aggregates is confirmed.
