Using Recycled Aggregates

Aggregate Base Course Our recycled concrete and recycled asphalt is frequently used as the foundation for roads and highway pavement and is generally accepted by the Department of Transportation. The aggregate base course is placed upon the subgrade directly underneath the paved surface and is a highly effective structural foundation for paving.♦.

Chapter Four

The base course in each pavement was a crushed Texas limestone meeting the Texas DOT Grade 1, Item 248, aggregate base specifica- tions. The test sections were instrumented with multidepth deflectometers (MDDs), and an FWD was positioned directly over the MDDs and at several different positions away from MDD and the pavement responses.

What is crushed aggregate base?

 · There are desirable properties associated with Aggregate Base Course (ABC). In pavements, Base Course is a sub-layer material that provides a supportive foundation on sidewalks top layers, that is placed directly on the undisturbed soil. The aggregates derive from concrete, recycled asphalt, or quarried rock. Structural Uses of Aggregate Base.

Construction Manual

The Specifications also require that any aggregate base course (ABC) placed between November 16 and March 15 inclusive must be covered within 7 calendar days with a subsequent layer of pavement structure or a sand seal. The Specifications allow the hauling, with permission of the Engineer, of material over the lower layers of ABC.
