Embodiment 1

[0051] The self-compacting fast-curing pavement repair material in this embodiment is prepared from the following components by weight according to the following method:

[0052] (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℃;

[0053] (2) Add 30 parts of the novolak resin to the ceramic sand aggregate while it is hot and stir evenly to obtain a stable mixture;

[0054] (3) Add 1 part of urotropine to the reactant obtained in step (2) while it is hot, stir it evenly, and cool down naturally;

[0055] (4) The reactant obtained in step (3) is cooled to room temperature, and crushed to a particle size of 70-140 mesh, and sieved to obtain the required repair material.

[0056] The repair material prepared in this example has been tested, and its strength can reach 45 MPa after only heating for 60 minutes, which can fully meet the strength requirements of airports or highway pavements.

Embodiment 2

[0058] The self-compacting fast-curing pavement repair material in this embodiment is prepared from the following components by weight according to the following method:

[0059] (1) 95 parts of ceramsite aggregate with a particle size of 70-140 mesh and a specific gravity of 1.7-2.5 are heated to 700-800°C, and then naturally cooled to 90-100°C;

[0060] (2) Add 4 parts of the thermoplastic boron phenolic resin to the ceramsite aggregate while it is hot and stir evenly to obtain a stable mixture;

[0061] (3) While it is hot, add 10 parts of urotropine to the reactant obtained in step (2), stir it evenly and then cool down naturally;

[0062] (4) The reactant obtained in step (3) is cooled to room temperature, and crushed to a particle size of 70-140 mesh, and sieved to obtain the required repair material.

[0063] The repair material prepared in this example has been tested and only needs to be heated for 65 minutes, and its strength can reach 48 MPa, which can fully meet the strength...

Embodiment 3

[0065] The self-compacting fast-curing pavement repair material in this embodiment is prepared from the following components by weight according to the following method:

[0066] (1) Heat 85 parts of small steel ball aggregate 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;

[0067] (2) Add 10 parts of thermoplastic silicone modified epoxy resin to the small steel ball aggregate while it is hot, and mix it evenly to obtain a stable mixture;

[0068] (3) Add 2 parts of ammonium chloride to the reactant obtained in step (2) while it is hot, and stir it evenly and then cool down naturally;

[0069] (4) Cool the reactant obtained in step (3) to room temperature, crush it to a particle size of 20-40 mesh, and sieve to obtain the required repair material.

[0070] The repair material prepared in this example has been tested, and its strength can reach 60 MPa after only heating for 70 minutes, which can fully meet the strength...

Abstract

The invention belongs to the field of road construction, and in particular relates to a method for rushing to repair damaged road surfaces rapidly. The method for rushing to repair the damaged road surfaces rapidly comprises the following steps of: (1) placing an electric heating device to the pits of the damaged road surfaces; and (2) filling repairing materials into the pits of the damaged road surfaces, covering the electric heating device, meanwhile starting up the electric heating device, and heating for 50-70 minutes so as to enable the repairing materials to be heated up and cured, thereby repairing the damaged road surfaces. The repairing materials consist of 60-95 parts of dense aggregate, 4-30 parts of thermoplastic resin bonding agents as well as 1-10 parts of thermal initiation latent curing agents capable of inducing the thermoplastic resin bonding agents to be cured rapidly under the heating state. By utilizing the method, high-intensity road surface base materials can be formed within 50-70 minutes under the heating state, and the time for rushing to repair and curing is shortened greatly.

Description

Technical field [0001] The invention belongs to the field of road construction, and specifically relates to a method suitable for rapid rush repair of road engineering. Background technique [0002] With the rapid economic development of our country, the number of airport runways has increased rapidly, the construction of high-grade expressways, and the implementation of concrete projects such as urban squares and municipal highways have improved the quality of human life and promoted the healthy development of the national economy. Many existing roads use concrete for pavement construction, which not only has good quality but also has long service life. However, the repair of the concrete pavement after it is damaged during use is more complicated. It needs to be closed and shut down for repair. Larger machinery is needed to open the pavement and rebuild it. At the same time, the maintenance period is long. At present, the commonly used repair materials for concrete pavement re...
