Abstract: For two classes of hyperbolic systems of conservation laws new definitions of a $\delta$-shock wave type solution are introduced. These two definitions give natural generalizations of the classical definition of the weak solutions. It is relevant to the notion of $\delta$-shocks. The weak asymptotics method developed by the authors is used to describe the propagation of $\delta$-shock waves to the three types of systems of conservation laws and derive the corresponding Rankine-Hugoniot conditions for $\delta$-shocks.
