Superpave Mix Design - Pavement Interactive

Additionally, the maximum aggregate size can be influential in compaction and lift thickness determination. Gradation Specifications. Superpave mix design specifies aggregate gradation control points, through which aggregate gradations must pass. These control points are very general and are a starting point for a job mix formula. Aggregate ...


Aggregate size and lift thickness are inseparable. All mix selections should allow for at least 4 times the nominal maximum aggregate size for the desired lift thickness. This means 9.5mm aggregate surfaces should be a minimum of 1-1/2"thick. Please consult with the Maryland Asphalt Association for guidance in specifying the proper superpave

Provide coarse aggregate for asphalt concrete base used in flexible pavements consisting of CCS, gravel, or crushed air-cooled slag.


The effects of aggregate type, size, and content on the behavior of normal and high-strength concrete, and the relationships between compressive strength, flexural strength, and fracture energy are discussed. The concrete mixtures incorporate either basalt or crushed limestone, aggregate sizes of 12 mm ('h in.) or 19 mm (:Y. in.), and

Provide coarse aggregate free of coatings of clay and silt. Do not add soil materials such as clay, loam, or silt to compensate for a lack of fines in the aggregate. Do not blend overburden soil into the aggregate. Feed each material or size of material from an individual storage unit at a uniform rate.
