It is located under the surface layer consisting of the wearing course and sometimes an extra binder course. If there is a subbase course, the base course is constructed directly above thi

When layers are constructed of differently graded aggregate, fine grading of the lower layer will not be required except when millings are placed as the upper most layer.
No. 4 fraction only. Granular base and subbase materials, however, commonly include from 35 to 70 percent plus No. 4 aggregate, which necessitates making a correction to the laboratory density figures to compensate for the effect of the oversize particles. The formula that has been used in Virginia assumes that the minus No. 4 material is100% compaction for aggregate basecourse/subbase? EngTips,201223· 18 May 11 15:41 I'm writing an RFI requesting revision of a spec calling for 100% compaction on aggregate basecourses and subbases under asphalt paving and PCC paving. Anyone here ever required such a thing for base courses?? The state DOT standard only requires a 95% for all basecourse/subbase.
