density of graded aggregate base

Aggregate Base Density Data - Earthwork/grading ...

09/06/2005  The (150-180) density data comes from a "Design and Control of Concrete Mixtures" book and appears to refer to the "particle" density of aggregate. However, since the aggregate is made up of particles, it is reasonable that the compacted density of the aggregate is between (150-180 lb/ft^3).

*Please note this tool is intended to be a guide only as the exact conversion depends on a number of factors beyond our control, for example the bulk density of the aggregate, moisture, method and degree of compaction, type of sub-base etc. Your contractor on site should confirm all quantities prior to ordering.

Density of Aggregate - Bulk and Relative Density - Civil ...

The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m 3 (75-110 lb/ft 3). Here, the Standard test method for determining the bulk density of aggregates is given in ASTM C 29 (AASHTO T 19). [2] Relative Density of Aggregate [1] The relative density (specific gravity) of an aggregate is the ratio of its mass to the mass of an equal ...

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.

DEPARTMENT OF HIGHWAYS

Density requirements for crushed graded aggregate base courses are necessary to obtain the desired performance, i.e. to develop shear­ ing strength and to eliminate subsequent consolidation. The load trans­ mission of a particular base material is thereby indirectly dependent upon density, Listed below are some of the factors that affect the density of dense­ graded aggregate base ...
