Problems solved by technology

At this time, in order to melt the asphalt, it is necessary to heat the road surface, and the process is complicated and takes a long time.
In addition, the hardening speed of the relaid material is slow, and it is necessary to prohibit or restrict the passage of vehicles for a long time, resulting in traffic congestion
Not only that, due to the poor bonding force of the part where the existing pavement material and the re-paved material are combined, the re-paved part is easily damaged again or separated from the existing pavement, and there are problems such as short service life and high maintenance costs

Embodiment approach

[0040] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0041] figure 1 It is a partial shedding and damaged part on the overall asphalt pavement, and a sectional view of the state after this type is repaired by the present invention.

[0042] Such as figure 1 As shown, the existing paving body (10) refers to the general asphalt pavement, and the damaged part (10a) refers to the local damage formed on the existing paving body (10) in a large range, such as Figure 5 The bumpy part of the photo.

[0043] The aggregate of the existing paving body (10) falls off partially to form a damaged part (10a), and the damaged part (10a) is subjected to rolling impact when the vehicle passes, not only the gravel combined on the road surface in an independent state will be damaged again, Moreover, the concave part of the road surface will also cause impact on the vehicle and cause damage to the vehicle. In severe cases, it will...

[0063] Before making quick-hardening epoxy mastic, it is first necessary to prepare a mixture of 20% quick-hardening epoxy resin, 80% silica sand with a particle diameter of 20-100 mesh, 25% quick-hardening epoxy resin, and silica sand with a particle diameter of 20-100 mesh. 75% mixture, 33% quick-hardening epoxy resin, 67% mixture of silica sand with a particle diameter of 20 to 100 meshes, and then mix according to their respective proportions to make blocks (hereinafter referred to as " patching material blocks") after hardening.

[0064] Separately take a piece of asphalt that is actually in use, and harden it after applying the material on its surface.

[0065] As a comparison material, take a piece Figure 5 The asphalt pavement material shown in actual use is the aggregate (95% by weight) formed by mixing gravel and sand used in general asphalt pavement and asphalt (5% by weight) that is heated and melted into a liquid state. ) mixed materials. The asphalt pavement ...

Abstract

The present invention relates to a repair material for an asphalt road and a method for repairing roads using the same. More specifically, the present invention provides a repair material capable of selectively filling a relatively wide damaged portion and a relatively small crack portion such as a crack on an asphalt road, reduces construction time by removing a step for heating asphalt and quickening the curing speed of the repair material, prevents water permeation by having excellent binding force with existing road pavement materials and waterproof properties, and further improves durability even when dynamic loads of vehicles are repetitively generated by having repaired road surfaces connected to each other. To this end, the repair material for an asphalt road comprises epoxy mortar which is formed from high speed hardening epoxy and silica sand, and the method for repairing roads using the same comprises the first step of preparing epoxy mortar by mixing the repair material on the repair portion of an asphalt road, the second step of filling the damaged pavement surface with the epoxy mortar and then carrying out plastering work, and the third step of hardening the repair pavement material.

Description

technical field [0001] The present invention relates to a road repairing material capable of repairing damaged or cracked parts of asphalt pavement, and a method of using the repairing material. Background technique [0002] Generally speaking, traffic road surface can be divided into asphalt pavement and concrete pavement. The asphalt used in the present invention refers to the residue obtained after volatilizing most of the volatile oil in petroleum crude oil, which is mainly black or dark brown. [0003] Bitumen is produced naturally and artificially from petroleum. Most of the asphalt currently used to lay roads is petroleum asphalt. Bitumen becomes liquid at high temperatures and very hard at low temperatures. When laying roads, asphalt in its solid form is heated to turn it into a liquid state. Pour about 5-6% asphalt into gravel, sand, stone powder and other aggregates, mix it, lay it on the road and compact it, and finally form an asphalt road. [0004] The pavin...
