Embodiment 1

[0039] The self-compacting fast-curing pavement patching material described in this embodiment is prepared according to the following method from the following components by weight:

[0040] (1) Heat 60 parts of ceramic sand aggregate with a particle size of 70-140 mesh and a specific gravity of 1.8-2.0 to 150-160°C;

[0041] (2) Add 30 parts of thermoplastic phenolic resin into the clay aggregate while it is hot and stir evenly to obtain a stable mixture;

[0042] (3) Add 1 part of urotropine to the reactant obtained in step (2) while it is hot, stir evenly and cool down naturally;

[0043] (4) Cool the reactant obtained in step (3) to room temperature, crush it to a particle size of 70-140 mesh, and sieve it to obtain the required repair material.

[0044] The repair material prepared in this embodiment is tested, and its strength can reach 45 MPa only by heating for 60 minutes, which can fully meet the strength requirements of airports or expressway pavement.

Embodiment 2

[0046] The self-compacting fast-curing pavement patching material described in this embodiment is prepared according to the following method from the following components by weight:

[0047] (1) Heat 95 parts of ceramsite aggregate with a particle size of 70-140 mesh and a specific gravity of 1.7-2.5 to 700-800°C, and then naturally cool to 90-100°C;

[0048] (2) Add 4 parts of thermoplastic boron phenolic resin to the ceramsite aggregate while it is hot and stir evenly to obtain a stable mixture;

[0049] (3) Mix 10 parts of urotropine into the reactant obtained in step (2) while it is hot, stir evenly and cool down naturally;

[0050] (4) Cool the reactant obtained in step (3) to room temperature, crush it to a particle size of 70-140 mesh, and sieve it to obtain the required repair material.

[0051] The repairing material prepared in this embodiment is tested, and its strength can reach 48MPa only by heating for 65 minutes, which can fully meet the strength requirements o...

Embodiment 3

[0053] The self-compacting fast-curing pavement patching material described in this embodiment is prepared according to the following method from the following components by weight:

[0054] (1) Heat 85 parts of small steel ball aggregates with a particle size of 20-40 mesh and a specific gravity of 7.9 to 160-200°C, and then naturally cool to 90-100°C;

[0055] (2) Add 10 parts of silicone-modified epoxy resin to the small steel ball aggregate while it is hot, and mix evenly to obtain a stable mixture;

[0056] (3) Add 2 parts of ammonium chloride to the reactant obtained in step (2) while it is hot, and let it cool down naturally after stirring evenly;

[0057] (4) Cool the reactant obtained in step (3) to room temperature, crush it to a particle size of 20-40 mesh, and sieve it to obtain the required repair material.

[0058] The repair material prepared in this example is tested, and its strength can reach 60 MPa only by heating for 70 minutes, which can fully meet the stre...

Abstract

The invention belongs to the field of casting materials, and particularly relates to a pavement patching material with relatively high self-compaction and capable of being quickly cured, a preparation method of the pavement patching material, and application of the pavement patching material in the field of quickly carrying out rush repair. The self-compact and quickly-cured pavement patching material comprises the following components in parts by weight: 60 to 95 parts of dense aggregate, 4 to 30 parts of thermoplastic resin adhesive, and 1 to 10 parts of thermal initiation latent curing agent which can induce the thermoplastic resin adhesive to be quickly cured at a heating state. The pavement patching material can form a high-strength pavement base material within 50 to 70 minutes at a heating state, so that the time for rush repair and curing is greatly reduced.

Description

technical field [0001] The invention belongs to the field of casting materials, and in particular relates to a self-compacting and rapidly solidified coated sand material and a preparation method thereof, as well as an application in the field of rapid repair of road surfaces. Background technique [0002] With the rapid development of my country's economy, the number of airport runways has increased rapidly, a large number of high-grade highways have been constructed, and the implementation of concrete projects such as city squares and municipal highways has improved the quality of human life and promoted the healthy development of the national economy. Most of the existing roads use concrete construction pavement, which not only has good quality but also has a long service life. However, the maintenance of the concrete pavement after the pavement is damaged during use is more complicated. It needs to be closed and out of service for repair, and it needs to use relatively l...
