• Aggregate Base Course Acme Sand Gravel

    ConstructionUseAppearanceAggregate 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 sizes of aggregate rock inclusive of 1 to fine dust. Aggregate is made from quarried rock, recycl在acmesand上查看更多信息
