AGGREGATE BASE COURSE MATERIAL TESTING AND RUTTING

A complete suite of characterization tests were conducted on 16 aggregate materials with laboratory samples consistently prepared for a mid-range dense-graded base course gradation. The tests included imaging-based aggregate particle shape analyses, moisture-density, resilient modulus, shear strength, and permanent deformation.

What is crushed aggregate base?

08-08-2018  Structural Uses of Aggregate Base. When doing structural foundations or base course under concrete slabs and asphalt pavement roadways, Aggregate Base is in use. It can be placed by attentive spreading then compacting. The sub-base if formed by dust and small chipped aggregate layers, typically Crushed Fines. The crushed aggregate base lays on heavy traffic or driveways areas. Dense Aggregate Base
