Description

High-level mastic asphalt concrete construction materials and their construction methods improved CO2 generation reduction and construction by sis} using SIS to reduce CO2 generation and improve workability.

The present invention relates to a paving goose asphalt concrete composition and a construction method thereof, including SIS and fine powder aggregate of improved aggregate particle size, and a method of construction thereof, and more particularly, SIS and improved aggregate particle size for improving the physical properties of asphalt concrete. It relates to a paving goose asphalt concrete composition and its construction method, which is a commonality grade with high PG grade performance (PG 82-34) including fine powder aggregate of, and has good crack reduction effect and adhesion and improved waterproof performance.

In general, the conventional heated asphalt mixture, which was mainly used for road pavement, cannot be installed by the cold-cooled ground construction method that is constructed at sub-zero temperatures during the winter season. In addition, in the summer or when changes in temperature and load occur, bending ( rutting phenomenon), irregularities in the longitudinal section, corrugation phenomenon, and leveling phenomenon occur repeatedly, causing cracks in the road, port holes, peeling and separation of aggregates, etc., reducing the life of the road.

Therefore, on average, re-paving, refurbishing, and repairs were continuously repeated every 4 to 5 years, which acted as a major factor in increasing the budget for maintenance every year rather than the pavement budget for new roads in the country.

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

The goose asphalt mixture, also called asphalt coule, is a special asphalt pavement material 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.

As described above, the goose asphalt mixture has a variety of advantages compared to the conventional heated asphalt mixture, but it does not require compaction in construction, so it is installed by a manpower plastering method or a professional finisher.

A conventional method for constructing such a goose asphalt mixture will be described as follows. The goose asphalt mixture is produced using a mechanical forced mixing method at high temperature (170℃~250℃) of mixed liquid, aggregate, sand, stone powder, etc., which are mixed in an appropriate ratio, and the weight of the mixture is 15 to 34% of the total weight of the mixture. It occupies a degree, and sand, aggregate, stone powder, etc. occupy 85-66% of the total weight of the mixture.

The mixed solution mixed with the goose asphalt mixture has high bonding strength, durability, and waterproof properties that can overcome all of the disadvantages caused by temperature or load changes, unlike the existing heated asphalt solution.

Particularly, when a large amount of mixed liquid is added and heated and mixed at a high temperature, the mixture has excellent fluidity as if lava erupted from a volcano flows down, and as it is naturally cooled, the pavement layer can be integrated without performing a compaction process.

In the case of direct production and construction of the above-mentioned goose asphalt mixture on site, a forced heating mixer, a quantitative supply device for mixed liquid, a heater that heats aggregate, sand, stone powder, etc. A supply device to supply, a mixed liquid heating device, a fuel supply device, an electricity and power supply device, a quality control device that controls all of them, other equipment, tools, miscellaneous materials, etc. are required.

As described above, the asphalt pavement occasionally undergoes plastic deformation along the running track 5 years after construction, causing serious driving problems, or even if there is no plastic deformation problem, the pavement material gradually ages with the passage of time. There is a problem in that a severe crack is generated and maintenance must be performed periodically. As an example of such a repair method, Korean Patent Registration No. 0880030 includes 60 to 80% by weight of asphalt cement; An asphalt composition for emergency repair of road pavement comprising a binder, comprising 15 to 35% by weight of vegetable oil, and comprising Aliphatic polyamides is disclosed.

Moreover, until now, as a method of paving concrete structures, roads, and/or bridges, a conventional method of overlapping a general modified asphalt of grade 2 to 3 (PG64-22.76-22), a concrete composition or a repair mortar has been applied.

However, the 2 to 3 grade concrete has a short lifespan, lacks adhesion and flexibility, frequently causes material separation and portholes, and poor waterproof performance.

Accordingly, in order to minimize the cost of maintenance, it is required to develop a paving goose asphalt concrete composition that minimizes plastic deformation, does not age for a long time, does not peel off easily, and improves waterproof performance.

The asphalt according to the present invention is not particularly limited as long as it is an asphalt commonly used in the art, but petroleum-based asphalt or an asphalt mixture may be recommended.

The asphalt mixture is not particularly limited as long as it is an asphalt mixture commonly used in the art, but preferably, straight asphalt, Trinidad lake asphalt, Trinidad epure asphalt, or at least one selected from these It is preferable to use the above mixture, more preferably straight asphalt having a penetration degree of 20 to 40 and a mixture of, for example, Trinidad Epure asphalt and/or Trinidad Epure asphalt, more preferably 20 to 40 penetration. It is recommended to use a mixture of 70 to 80% by weight of straight asphalt and 20 to 30% by weight of asphalt consisting of Trinidad Epure asphalt or Trinidad Epure asphalt.

Here, the straight asphalt is a conventional asphalt obtained by distilling or distilling raw materials with petroleum asphalt, and having a degree of penetration of 20 to 40 is more preferable because of its ease of construction on a road.

The straight asphalt is preferably contained in the asphalt mixture in an amount of 70 to 80% by weight. If the content is less than 70% by weight, it may take a long time to harden after paving the asphalt, the softening point may be lowered, and if it exceeds 80% by weight, the fluidity may be lowered.

In addition, the asphalt functions to improve the fluidity of the pavement goose asphalt concrete composition, which includes the SIS of the present invention and the fine powder aggregate of the improved aggregate particle size, and improves the waterproof performance, and increases deformation resistance, sliding resistance, and friction resistance. .

As the asphalt, Trinidad lake asphalt and/or Trinidad epure asphalt may be used.

The asphalt is preferably contained in an amount of 20 to 30% by weight in the asphalt mixture, and when the content is less than 20% by weight, the effect of improving fluidity, deformation resistance, sliding resistance and friction resistance is insignificant, and may exceed 30% by weight. In some cases, the asphalt of the present invention may be softened and the softening point may be lowered.

Here, if the melting temperature of the petroleum resin is 100°C or less, it is not good because it may stick to each other or form a lump when the temperature is high. If the penetration is less than 0.5dmm, it is too soft to improve the high-temperature properties of asphalt. It becomes a problem.

In addition, if the viscosity of the petroleum resin at 140°C is 500 cps or more, the viscosity is higher than that of asphalt, so the manufacturing time is too long.

Here, if the melting temperature of the petroleum resin is 100°C or less, it is not good because it may stick to each other or form a lump when the temperature is high, and it may be a defective product. It becomes a problem.

In addition, if the viscosity of the petroleum resin at 140°C is 500 cps or more, the viscosity is higher than that of asphalt, so the manufacturing time is too long.
