Viscosity properties of bimodal bitumen emulsions: new approach

The emulsions used in the manufacture of half warma sphat should contain very little water in their formulation. Conventional monomodal emulsions have a maximum dispersed phase concentration, ϕ, of 0.69. Recent research in this field is focused on the development of concentrated emulsions, ϕ = 0.70-...
