Aggregate road base material 1

[nagatalluri]

Hello

I am working on aggregate road base material for access roads in a project. These roads are meant for a wind project component delivery. The contractor is using KDOT AB-3 material for the aggregate base.

Compaction tests conducted on this material showed OMC 13.5% and MDD 113pcf. We have compaction results from the same site where the native soil (Lean clay) has OMC 15% and MDD 111pcf.


Have you encountered any such materials from your experience in the past. The reason is I am checking other road aggregate materials and they have OMC 6-8% and MDD in the range of 130-140 pcf.

I am wondering if this material could really be used for road construction ? if roads are constructed using such material do they last?

Any input on the range of moisture and MDD for road aggregate materials

Your help is appreciated

Thanks

Yes! Roadway materials vary. A lot depends on the specific gravity of the material, with respect to its ultimate MDD.

Provided the stability requirements (CBR>80) are met, the MDD doesn't mean much except for compaction purposes.

it varies like geology across the world. it would make my life easier if everybody at least agreed to use a common "name" for the stuff that goes under the pavement
