Resin cement for levelling cement concrete road surface

Abstract

The invention relates to the field of road construction, in particular to resin cement for levelling cement concrete road surface. The resin cement for levelling cement concrete road surface overcomes the shortages of existing methods for levelling cement concrete road surface and especially solves the problem that common cement concrete has the disadvantages of low cement concrete bonding strength, slow strength development, long solidification time, long traffic hampering time and the like when common cement concrete is used for repairing road surface. The resin cement is prepared from 10-20% of epoxy resin, 0.2-0.5% of curing agent, 5-15% of polyving alcohol particle of which the particle size is 2-3cm, 3-10% of polyving alcohol powder of which the particle size is 70-80 meshes, 5-10% of 108 glue, 2-6% of asbestos fiber with 70-80 meshes, 0.5-2% of common silicate cement, 2-5% of sand and water. The resin cement has strong cohesive force with old road surface after solidifying, does not need to cut and chip damaged sites of the old road surface, has the characteristics of quick hardening, early strength, small contraction, small chromatic aberration with old concrete, strong cohesive force, abrasion resistance, endurance and convenient construction and is favourable for improving road surface repair quality and speed.

[0001] The invention relates to the field of road construction, in particular to resin cement for leveling cement concrete road surfaces. Background technique

[0002] As one of the important forms of high-grade pavement, cement concrete pavement has been widely used more and more. Cement concrete pavement has the advantages of high strength, durability and low maintenance cost. However, during the use of cement concrete pavement, due to the repeated action of traffic load, the continuous influence of various environmental factors, coupled with many factors such as design, construction and maintenance, damage will inevitably occur. Once the cement concrete pavement is damaged, it is difficult to repair, the maintenance period is long, the traffic is affected, and the maintenance cost is high. With the emergence of cement concrete pavement damage, the research and exploration of cement concrete pavement effective and rapid repair materials and processes have...
