Effective Repair and Refurbishment Compound for the Strengthening of a Road Concrete Pavements

Road pavements for various purposes are constantly exposed to high traffic loads, high temperature changes and aggressive influence of ice-reagents during winter, which cause a negative effect on the durability of concrete. To restore the weakened concrete properties and further protection an effective multifunctional material is needed.A composite repair-protective material modified by a mixture of developed complex additive has a compressive strength not less than 55,0 MPa, the abrasion resistance mark corresponds to an abrasion brand G1, frost resistance corresponds to brand F2400, and wherein has a high adhesive strength equal to 3,2 MPa for concrete B40 pavement providing a monolithic composition. This material also has a high corrosion resistance. The designed repair material has a protective penetrating ability, thereby increasing the strength of the concrete pavement on 2 classes, and increasing the frost resistance on 100 cycles. The designed repair and protective material successfully passed the pilot tests at the seaport territory.
