Description

[0001] The present invention relates to a colorless mastic asphalt concrete composition using SIS,

The present invention relates to a colorless mastic asphalt concrete composition using SIS and a method of applying the same. More particularly, the present invention relates to a colorless mastic asphalt concrete composition using SIS capable of improving durability, water resistance and chloride penetration resistance, ≪ / RTI >

In general, the conventional heated asphalt mixture used mainly for road pavement can not be installed by the cold-applied construction method which is applied at the sub-zero temperature in the winter, and when the summer season, temperature and load change occur, rutting phenomenon), irregularities of the longitudinal section, corrugation phenomenon and leveling phenomenon repeatedly occur, which causes the cracks of the road, the port hole, the peeling of the aggregate, and the deviation of the aggregate.

Therefore, on average, repacking and repairs were repeated over a period of four to five years. This contributed to a yearly increase in the budget for maintenance, rather than the packaging budget for the establishment of the national road.

In order to overcome this problem, a goosal asphalt mixture having excellent imperviousness, durability, abrasion resistance, impact resistance, flexibility, slip resistance and adhesiveness has been developed instead of the conventional heated asphalt mixture.

The goos asphalt mixture, also known as the asphalt coule, is a special asphalt pavement developed in France and is referred to as goose asphalt in Germany and Japan and asphalt mastic or mastic asphalt in the United Kingdom and the United States.

The Goose asphalt mixture has various advantages compared to the conventional heated asphalt mixture as described above, and it is unnecessary to compaction even in the construction, so that it is installed by a work finishing method or a professional finisher.

A conventional method for constructing such a cusp asphalt mixture will be described below. The goosel asphalt mixture is produced by mechanically mixed mixing method at high temperature (170 ℃ ~ 250 ℃) in the mixed ratio, aggregate, sand, Of the total weight of the mixture, and the sand, aggregate, and stones account for 85 to 66% of the total weight of the mixture.

Unlike conventional heated asphalt solution, the mixed solution mixed with Goose asphalt mixture has high bonding strength, durability and waterproof property which can overcome all the disadvantages caused by temperature or load change.

Particularly, when a large amount of mixed liquid is added and heated and mixed at a high temperature, the mixture has excellent fluidity as the lava ejected from the volcano flows down. As the natural cooling, the packed layer can be integrated without performing the compaction process.

When the above-mentioned goos asphalt mixture is to be directly produced on site, it is necessary to mix materials such as mixture, aggregate, sand, and stone, a forced heating mixer, a mixed liquid quantity feeder, a heater for heating aggregate, sand, A supply device, a mixture liquid heating device, a fuel supply device, an electricity and a power supply device, a quality control device for coordinating all of them, other equipment and tools, and a job material.

As described above, the asphalt pavement is sometimes subjected to plastic deformation along the running track 5 years before the construction, causing severe driving problems, and even if there is no plastic deformation problem, the packaging material gradually ages with the passage of time There is a problem that maintenance is required periodically due to occurrence of severe cracks. As an example of such a repair method, Korean Patent Registration No. 0880030 discloses that 60 to 80% by weight of asphalt cement; And 15 to 35% by weight of a vegetable oil; and an aliphatic polyamide (Aliphatic polyamide) is contained in the asphalt composition.
