Experimental results, including the selection of repair concrete and steel-fiber-concrete mixtures for rigid pavement repair are presented. The complex effect of the superplasticizer, hardening accelerating agent and steel anchor fiber on the concrete mixture properties has been studied. Compressive and flexural strength characteristics of the repair material were determined in the early and design ages of hardening. Using the method of experimental statistical modeling, the optimal dosages of dispersed reinforcement in combination with accelerating agent and workability modifier have been determined.
