I regret that cohesion and/or adhesion can not be determined from bulk density. These physical properties of soil are more a function of clay minerology and clay content and are further influenced by water content. I would suggest that soil texture would be a better place to start. I refer you to general soils textbooks such as Miller and Gardiner, 1998. Soils in OUr Environment.
