PDF Asphalt Mix Design - Foundation Performance

Mix Composition The rule of thumb would be to never allow a different material or different source to be used than what is on the mix design. You need to know if your local agency allows: •Switching binder grade on same design (maybe) •Switching binder source within same grade (maybe) •Aggregate Types (never) •Aggregate Sources (never)

History of asphalt mix design in North America, Part 1 ...

Hveem’s mix design philosophy is that sufficient asphalt binder is needed to satisfy aggregate absorption and to have a minimum film thickness on the surface of the aggregates. In order to carry load, the aggregates had to have a sliding resistance (measured by the Hveem stabilometer) and a minimum tensile strength to resist turning movement (measured by the cohesiometer).

Cold mix asphalt: An overview - ScienceDirect

Asphalt mix design methods vary, worldwide like in USA, the SUPERPAVE method is widely implemented, in Europe and Asian countries, the MARSHALL method is used (Rubio et al., 2012). In HMA, heating is used to achieve the required viscosity and workability whereas in case of CMA it is achieved by using water, emulsifier agent or solvent whereas ...
