Bituminous Material - an overview | ScienceDirect Topics

The term soil-bitumen (or soil-asphalt) has been used to refer to a waterproofed cohesive soil, typically employing the use of ~ 4-7% bitumen. Asphalt concrete usually refers to stabilized granular soil, where sand or well-graded aggregate is mixed with between 3% and 10% bitumen to provide a durable water- and abrasion-resistant structural layer.

Bituminous Mix - an overview | ScienceDirect Topics

Asphalt concrete is a combination of two primary ingredients: (i) aggregate and (ii) asphalt cement. Typically, the aggregate constitutes 90–95% (w/w) of the total mixture and the asphalt cement (asphalt binder) constitutes 5–10% (w/w) of the total mixture to form the asphalt concrete. In the production process, the aggregate and binder are ...

Aggregates - Portland Cement Association

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
