Selecting the correct materials Asphalt magazine

The maximum particle size is important because it controls the appropriate lift thickness of the mixture placement. For good paving results, the lift thickness of a dense-graded asphalt mix should be 2½ to 3 times the maximum aggregate size or 3 to 4 times the nominal aggregate size in the mix.

Asphalt Pavement Thickness and Mix Design Asphalt Institute

In order to be compacted, the mixture must have controlled workability. Typically, for dense-graded mixes, a lift thickness of 3 to 4 times the nominal maximum size (NMS) of the aggregate is needed. For example, a mix containing ½-inch NMS stone should be placed at

Lift thickness governs aggregate size. Minimum lift thickness should be at least 3 times the nominal max. aggregate size to ensure aggregate can align themselves during compaction to achieve required density and also to ensure mix is impermeable. The maximum lift thickness is dependent also upon the type of compaction equipment that is being used.

HOT MIX ASPHALT PAVEMENT DESIGN GUIDE

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

Chapter 2 Asphalt and Asphalt Paving Materials

AGGREGATES Aggregates (or mineral aggregates) are hard, inert materials such as sand, gravel, crushed stone, slag, or rock dust. Properly selected and graded aggregates are mixed with the cement-ing medium asphalt to form pavements. Aggregates are the principal load-supporting components of an Asphalt Concrete pavement.

The available nominal aggregate sizes are 4.75 mm, 9.5 mm, 12.5 mm, 19.0 mm, and 25.0 mm. Mixtures with larger nomin al aggregate size designations have larger particle sizes in their gradations. The maximum particle size in a mixture is larger than the size in the nominal aggregate designation, so refer to 401.05 for gradation range information.
