Embodiment 1

[0010] Resin cement for cement concrete pavement leveling is made of the following raw materials in weight ratio: 10% epoxy resin, 0.2% epoxy resin curing agent (T-31), 5% polyvinyl alcohol particles with a particle size of 2 cm, and a particle size of 3% of 70 mesh polyvinyl alcohol powder, 5% of 108 glue, 2% of 50 mesh asbestos fiber, 0.5% of ordinary Portland cement, 2% of sand, and the rest is water.

[0011] The construction method is as follows: 1. Base treatment: clean up the dust, floating soil, oil stains and other pollutants that affect the bonding of the base layer, and clean up the broken pieces that have moved, and moisten the base with water; Mix epoxy resin, curing agent, polyvinyl alcohol, 108 glue, and asbestos fiber, then add water, cement, and sand, and stir evenly to avoid air bubbles; 3. Construction: Apply directly or pour on the diseased surface when the base is wet. The part can be scraped flat, it can be cured in 30 minutes, and the traffic can be resu...

Embodiment 2

[0013] Resin cement for cement concrete pavement leveling is made of the following raw materials in weight ratio: 20% epoxy resin, 0.5% polyamide curing agent (115), 15% polyvinyl alcohol particles with a particle size of 3 cm, and a particle size of 80 mesh 10% of polyvinyl alcohol powder, 10% of 108 glue, 6% of 80-mesh asbestos fiber, 2% of ordinary Portland cement, 5% of sand, and the rest is water. Construction method is the same as embodiment 1.

Embodiment 3

[0015] Resin cement for cement concrete pavement leveling is made of the following raw materials in weight ratio: 10% of epoxy resin, 0.5% of polyamide curing agent (115), 15% of polyvinyl alcohol particles with a particle size of 2-3cm, and a particle size of 3% of 60-mesh polyvinyl alcohol powder, 10% of 108 glue, 6% of 80-mesh asbestos fiber, 2% of ordinary Portland cement, 2% of sand, and the rest is water. Construction method is the same as embodiment 1.

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.

Description

technical field [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...
