Selecting the correct materials | Asphalt magazine

Aggregate gradation is the distribution of the various particle sizes. 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 densegraded asphalt mix should be 2½ to 3 times the maximum aggregate size or 3 to 4 times the nominal ...
