Problems solved by technology

[0004] The asphalt filling repair method has the following problems: the flatness is reduced due to the deformation of the existing road surface, and reflection cracks occur in which the filled layer that has cracks in the lower layer also cracks.
[0012] Resin paste is paved with thin layers of resin such as epoxy, polyester resin, acrylic monomer, polyurethane, and polyurea resin. Due to the difference in hardening expression according to the construction temperature, the material mechanics between resin and asphalt pavement Differences, reduced durability, and as an expensive material, its economical efficiency is low, making it dif

Embodiment Construction

[0064] Specific examples are given below to describe the present invention in more detail. However, the scope of the present invention is not limited to the descriptions of the Examples, and it is obvious to those skilled in the art to which the present invention pertains.

[0065] Table 2 lists the composition ratios of asphalt binders using the above-mentioned asphalt additives of the present invention. What did not add the additive of this invention was used as a comparative example.

[0066] Table 2

[0067] Composition ratio (weight percent) Example 1 Comparative example 1 Additives of the present invention 2～6 3.5 - Modified asphalt 94～98 96.5 100

[0068] In the asphalt binder of the present invention, when the additive is less than 2% by weight, it is difficult to give full play to the function of the additive; when it exceeds the range of 6% by weight, excessive fluidity will cause the binder to break down. The physical propertie...

Abstract

The invention discloses a reflection crack resistant, low noise, highly durable asphalt mixture and its thin layer surfacing pavement method. Provided are: an economic and eco-friendly asphalt additive for inhibiting reflection crack and enhancing the durability of a road; an asphalt mixture comprising the same; and a method for paving a thin layer using the same. The inventors invents: a plant-type asphalt additive in which plant oil, naphthene-based oil, a mineral fiber, and an organic vulcanization accelerator are mixed; a low-noise asphalt mixture comprising the additive; and a method for paving a reflection crack-resistant, low-noise, and highly durable thin layer using the asphalt mixture.

Description

technical field [0001] The invention relates to a low-noise and high-durability asphalt mixture for suppressing reflection cracking and a thin layer paving method using the mixture. Background technique [0002] The design life of asphalt concrete pavement in Korea is 20 years, including one maintenance, but the actual maintenance is performed every 2 to 3 years. It is an indisputable reality that road life is shortened due to the increase in traffic volume and heavy vehicles, and frequent resurfacing is required as users' expectations for roads increase, resulting in heavy economic pressure. [0003] The road pavement maintenance process can be divided into cutting filling and non-cutting filling, and the non-cutting filling process is divided into general filling and thin layer filling. [0004] The asphalt filling maintenance method has problems in that the flatness is lowered due to deformation of the existing road surface, and reflective cracks occur in which the filli...
