The invention relates to a rubber elastic self-compaction concrete for plate-type ballastless tracks, which is used for obviously enhancing the compression strength of the self-compaction concrete and enabling the self-compaction concrete to have favorable shock absorption and damping capacities. The rubber elastic self-compaction concrete for plate-type ballastless tracks can be used as a filler between the track plate and the bottom plate in a CRTS III plate-type ballastless track structure, and can also be used as a filler between a switch plate and the bottom plate in a switch structure. The self-compaction concrete is composed of the following components in parts by weight: 100 parts of cement, 4-10 parts of rubber powder, 30-60 parts of mineral admixture, 250-300 parts of fine aggregate, 250-300 parts of coarse aggregate, 1-2 parts of basalt fiber, 5-15 parts of expanding agent, 1.0-2.0 parts of water reducing agent, 0.01-0.05 part of rheologic assistant, 0.001 part of defoaming agent and 40-60 parts of water. The grain fineness of the rubber is 30-50 meshes, and the surface of the rubber is previously treated with polyvinyl alcohol and a silane coupling agent.
