Base course is a layer of material in pavements, such as asphalt roadways, race tracks, or sporting fields. It is usually made of a construction aggregate, such as crushed rock, and provides a stable foundation for the surface layer.
Learn how to construct a base course for road paving, which provides support and stability to the surface course. Find out the materials, specifications, and methods for dry-bound, water-bound, and penetration macadam bases.

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. It is typically made of a recipe of different...
Aggregate Base is used as the base course under asphalt pavement roadways, under concrete slabs and structural foundations, and as backfill material for underground pipelines and other underground utilities within a roadway. It is placed by means of attentive spreading and compacting to a minimum of 95% relative compaction, providing the stable fou...
The Sub-Base is a layer of small chipped aggregate and dust, typically Crushed Fines, which is laid above the ABC on driveways or heavy traffic areas. The thickness of sub-base can range from 1 to 2 inches on light weight traffic areas like pathways and paver patios above the sub-grade when a ABC is not required,
Learn about Aggregate Base Course (ABC), a sub-layer material of asphalt roadways and concrete slabs. Find out its properties, uses, thickness, and cross-section layers.
Aggregate base is a construction aggregate used as a base course in roadways, cement pads, foundations and underground utilities. It is composed of crushed rock or recycled asphalt and concrete particles that can pass through a 20 mm screen.
30 août 2024 · The base course is a layer of granular material placed directly on top of the subgrade and below the pavement layer. Its primary role is to support the pavement structure, enhance load distribution, and ensure the durability of the road.
30 août 2024 · The Aggregate Base Course (ABC) is a layer of aggregate material that is placed between the subgrade and the pavement surface. It is designed to provide a stable foundation for the road surface, distribute loads evenly, and enhance the overall performance of the roadway.
1 déc. 2018 · The purpose of this project is to investigate the long-term performance of gravel as base course layer material and assess the potential degradation over time. Aggregate degradation is defined as the breakdown of an aggregate into smaller particles [2].
