CHARACTERISTICS OF GRADED BASE COURSE AGGREGATES DETERMINED BY TRIAXIAL TESTS. Several series of triaxial compression tests are made to determine the effect of miximum size of aggragate, of fines passing No. 200 sieve, of plasticity, of shape of particle, of type of aggregate, and of blending aggregates of different types, on the strength and deformation of dense graded base course aggregates.

Mix Design of Cement-Stabilized Recycled Aggregate Base Course Material
The results showed that the use of 100% recycled concrete aggregates increased the optimum moisture content and decreased the maximum dry density of base course materials compared to those of natural base materials.

Long term performance of gravel base course layers in asphalt pavements
The aggregate samples were removed from the base layer with the aid of basic tools such as small shovels and hand-held pick-axes to dig down to the bottom of the base-course aggregate layer. It should be noted that the authors visually inspected the base course layers during sampling and looked for evidence of contamination, infiltration, or pumping of fine materials from subgrade soils.

Asphalt Concrete Base (ACB) – Pavement Interactive
Asphalt Concrete Base (ACB) Asphalt concrete base (ACB), also called asphalt treated base (ATB), is a dense-graded HMA with a larger nominal maximum aggregate size (1 inch) intended for use as a base course or binder course (see Figure 1). In addition to site paving benefits, ACB can be advantageous because it can provide:

[PDF] Sustainable Use of Crushed Concrete Waste as A Road Base Material
Crushed concrete waste is a by-product from building demolition and constitutes a principal component of municipal solid waste consisting of concrete, sand, brick, rock, metals and timber. Over 50% of this waste is commonly sent to land-filled sites, resulting in the impact on the limited capacity of land-filled sites. Nowadays, the sources of virgin natural aggregates aredepleted by increases

Aggregate Base Courses
For this reason, aggregate base courses are usually a graded mixture of soil elements (meaning they contain various sized particles) that bind crushed stone or gravel in a matrix. If desired base course attributes need to be especially emphasized in a pavement design due to challenging site conditions, sometimes two courses of base materials are placed, each having different soil constituents
