Types of Bitumen Mixes for Pavements -Applications in Road
The bitumen mix with a large amount of fine aggregate i.e. sand will form open graded bitumen mix. When the mix lack materials of two or more sizes, it will form gap graded bitumen mix. The semi-graded mix will have a gradation lying in between the open graded and the gap graded.

Page 1 CHAPTER 24. BITUMINOUS MIX DESIGN NPTEL May 3, 2007 Chapter 24 Bituminous mix design 24.1 Overview The bituminous mix design aims to determine the proportion of bitumen, ller, ne aggregates, and coarse aggregates to produce a mix which is workable, strong, durable and economical.
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 ...
