The invention relates to a dry material used for a cement emulsified bitumen mortar of vertical connecting plate type ballastless rails, which comprises the following components in portion by weight: 100 portions of gelled material, 138 to 195 portions of sand, 0.05 to 0.5 portion of fiber, 0.003 to 0.01 portion of aluminum powder, 0 to 0.1 portion of polymer, and 0 to 10 portions of stone dust. By adding fiber, particularly hydrophilic fiber to dry materials, the toughness, the shock resistance and the fatigue resistance of the mortar prepared from the dry materials can be improved, the bleeding phenomenon of the mortar can be avoided and the lasting quality of the mortar can be improved; simultaneously, by selecting different gelled materials, particularly the combinations of between the different gelled materials, the problem that the prior dry material and the mortar prepared from the dry materials are difficult to satisfy the requirements on various construction environments and use environments, particularly the environments with lower temperature can be solved.
