The base course is generally com posed of granular material such as crushed aggregate, gravel, selected soil, or a mix ture of selected soil and aggregate. Since the cost of the surface course per ton is sev eral times that of the base course, its thickness is generally just a fraction of

THE PROPERTIES OF AGGREGATE FOR DENSE GRADED BASE COURSE CONSTRUCTION J.E. GRAY Engineering Director, National Crushed Stone, Association, ·washington, D.C. The purpose of this paper is to discuss several aspects of dense graded aggregate base course construction which are essential to obtain the best in
Aggregate Base Course . Aggregate Base Course often referred simply as ABC, has certain desirable properties. Base Course in pavements refers to the sub-layer material of an asphalt roadway and is placed directly on top of the undisturbed soil (Sub-Grade) so as to provide a foundation to support the top layers of the pavement.
Highway base courses are typically constructed using crushed and processed aggregate. Crushed base aggregates are typically a cost effective means of carrying loads and reducing the thickness of the asphalt layer in paved roads. For some projects in Montana, however, obtaining materials

Aggregate base (AB) is typically made of a recipe of mixing different sizes of crushed rock together forming the aggregate which has certain desirable properties. 20 mm or 3 ⁄ 4 in Aggregate Base, Class 2 , is used in roadways and is an aggregate made of a specific recipe of different sizes and quality of rock inclusive of 20 mm ( 3 ⁄ 4 in) to fine dust.
Crushed and processed aggregate are typically a cost effective means of carrying loads and reducing the thickness of the asphalt layer in paved roads—but, for some projects (such as in Montana), obtaining materials that meet the current specifications for crushed base course is becoming uneconomical due to declining resources.
Crushed aggregate base course is a mixed stone with the dimensions of 0.075mm – 19mm, 0.075mm – 25mm with the following technical specifications: Technical specifications: Resistance to original rock compression (Mpa) >80; Los Angeles Abrasion on aggregate (LA),% ≤ 35

ing. These steps will be applied to the three main types of base courses
Crushed stone base courses have a CBR >100% - if I remember, offhand, this is "given" in AASHTO pavement design (else it is 80%). There is little difference between 80 and 100 or 120% as far as behaviour is concerned and I think that you can simply use the AASHTO recommendations. Most specifications I have seen for natural sand and gravel
drawings should be referred to as "graded-crushed aggregate base course (GCA)" wherever a base material with a CBR of 100 is required. "Graded-Crushed Aggregate Base Course" should be retained in the title and the rest of the specification should be edited accordingly to retain the information necessary for this material. c.
