Yes.
Bitumen is already water resistant - it is a mixture of long chain polymers, many of which are asphaltic.
You can make acrylic bitumen emulsions which are water dispersible but which, when cured (dried) have the same (or similar) water resistance as pure bitumen.
We need context to be able to answer this. These are two different categories of plastics, but what do you mean by "mixed"? Mixed where, and mixed how?
Many liquids can be mixed forming true solutions.

It varies: watercolor, oil, acrylic, mixed, ...
Acrylic paints are powdered colour that is mixed with a clear acrylic medium. It is insolvent once dry.
The binder of the acrylic paint is called "acrylic polymer emulsion," and it can be found in different forms, which can be referred to as the "acrylic mediums". The easiest way to make acrylic paint is to use Aqua - Dispersions of Pigments, which are completely ready to use when you buy them. Acrylic paint is fast drying that contains pigment suspension in acrylic polymer emulsion. This type of paint can be diluted with but are resistant to water when they dry. A finished acrylic paint can resemble an oil or water colour painting depending on how much the painting is diluted or modified with acrylic gels or pastes.
These solutions are not miscible.
Mixed media acrylic.
because they are not soluable
There are no best rated pastel paints in acrylic, because pastels and acrylics are different types of paints. Acrylic paints are made with synthetic resins, while pastels are made from ground pigment mixed with oil and wax.
