Description

[0001] The present invention relates to an asphaltic asphalt concrete composition for a surface layer having improved waterproof performance, including fine-particle aggregates of SIS and improved aggregate size, and a method of applying the same. for Improving Waterproof and Constructing Methods Using Thereof}

The present invention relates to a gussmastic asphalt concrete composition for a surface layer which is improved in waterproof performance by including SIS and fine aggregate aggregates having an improved aggregate particle size and a method of applying the same. More particularly, the present invention relates to an SIS and an improvement method for improving physical properties of an asphalt concrete (PG 82-34), including a fine aggregate of aggregate-size aggregate aggregate, and having improved cracking-reducing effect and adherence, and improved waterproofing performance, and a method for constructing the asphalt concrete composition for surface layer .

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 gas-mastic asphalt mixture having excellent imperviousness, durability, abrasion resistance, impact resistance, flexibility, sliding resistance and adhesiveness has been developed instead of the conventional heated asphalt mixture.

Goosmatic asphalt mixtures, also known as asphalt coulees, are special asphalt pavements developed in France and are referred to as goose mastic asphalt in Germany and Japan and asphalt mastic or mastic asphalt in the United Kingdom and the United States.

The goosmastic asphalt mixture has various advantages compared to the conventional heated asphalt mixture as described above. Since the compaction is unnecessary in the construction, it is installed by the work finishing method or the professional finisher.

A conventional method for constructing such a mixture of goeth mastic asphalt will be described as follows. Gusmastic asphalt mixture is produced by mechanical mixing method at high temperature (170 ℃ ~ 250 ℃) in mixed liquid, aggregate, sand, and stone mixed with appropriate ratio, 34% of the total weight of the mixture, and sand, aggregate, and stones account for 85-66% of the total weight of the mixture.

Unlike the conventional hot asphalt solution, the mixed solution mixed with the goosmastic asphalt mixture has high bonding strength, durability and waterproofing ability to 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 goosmastic asphalt mixture is to be directly produced on site, it is necessary to mix materials such as a mixture, aggregate, sand, and stone, a forced heating mixer, a mixed liquid quantity feeder, a heater for heating aggregate, sand, A fuel supply device, an electric and power supply device, a quality control device for coordinating all of them, other equipment and tools, and a job material are required.

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.

Moreover, conventional methods of overlaying general modified asphalt, concrete compositions or repair mortars of grades 2 to 3 (PG64-22.76-22) have been applied by way of concrete structures, roads, and / or bridge pavements.

However, the concrete of the second to third grades has a short lifetime and insufficient adhesion force and flexibility, so that material separation and portholes are frequently generated and waterproof performance is deteriorated.

In order to minimize the cost due to the maintenance, it is required to minimize the plastic deformation, develop aging of the goosmastic asphalt concrete composition for surface layer which is not easily peeled off for a long time, .

The present invention has been made in order to overcome the above-mentioned problems, and it is an object of the present invention to provide a waterproofing material which is capable of being directly blended in the field, has good waterproofness and durability and can prevent penetration water and portholes without plastic deformation, aging and / The present invention provides a surface-modified goeth mastic asphalt concrete composition having improved waterproof performance.
