Description

Asphalt Concrete Compositions Having Low Noise and Permeable Using Styrene Isoprene Styrene, Styrene Ethylene Butylene Styrene and Aggregate-powder of Improved Grain Size for Anti-freezing and Constructing Methods Using Thereof}

The present invention relates to a low noise drainage asphalt concrete composition for anti-icing, and more specifically, SIS, SEBS and improved aggregate particle size to have low noise and drainage properties and to prevent freezing at the same time by using SIS, SEBS and fine powder aggregates. It relates to a low-noise drainage asphalt concrete composition for preventing freezing containing fine powder aggregate and a construction method thereof.

In general, asphalt is a black or dark brown solid or semi-solid thermoplastic material composed of a very complex composition of thousands or more of high molecular hydrocarbons (C-H) containing organic compounds and trace amounts of inorganic compounds, and has the property of gradually changing to a liquid state when heated.

The asphalt is divided into natural asphalt, petroleum-based asphalt and paving tar, and straight asphalt and emulsified asphalt are widely known.

In addition, the asphalt is used as a bonding material or an adhesive material because it has excellent adhesion and excellent adhesion to mineral materials, and is also used as a waterproof material because it is not soluble in water and is impermeable, and the viscosity can be changed according to the purpose of use. Its application range is diverse, and it is used for various purposes such as road pavement, waterproofing, general industrial use, and agricultural use.

On the other hand, drainage asphalt concrete was first constructed in the UK in the 1950s to prevent water filming on the runway, and in the 1980s, high-viscosity modified asphalt was developed in Japan to improve durability due to the high porosity (open asphalt concrete), a disadvantage of drainage asphalt. However, since 2001, all expressways and general roads in Japan have been obligated to use drainage asphalt unless there is a special reason.

In Korea, since it was first tested and paved on the Gyeongbu Expressway in 1997, the Ministry of Construction and Transportation has designated the drainage pavement method as a new technology in 1999 and has been gradually expanding it. However, problems such as aggregate removal, plastic deformation, and potholes have occurred and technically needs to be supplemented. Actually.

Drainable asphalt has a porosity of 20% or more, so that rainwater is permeable in rainy weather and rainwater does not accumulate on the road surface. Compared to general asphalt, rainwater scattering during driving is small, and the formation of spray is small, so it is better to secure visibility when driving. In addition, since the water screen phenomenon is small and the road surface anti-slip effect of the car is large, the effect of preventing traffic accidents is large, and it absorbs the road surface friction sound caused by the air pumping phenomenon between the car tire and the road surface generated during driving due to the formed air gap. It is a high-performance asphalt that can reduce noise by about 4 to 8 dB.

However, since the contact area between the aggregates due to the high structural mechanically high voids of the drainage asphalt concrete is small, the aggregates are easy to detach and have low durability compared to general asphalt concrete.

In addition, water impermeable asphalt concrete is required to be impermeable in order to prevent ground subsidence caused by permeation of rainwater into the basement layer in the base or intermediate layer, and after forming an impermeable layer by tec coating, a drainage layer is installed thereon.

In general, the drainage layer is selected and used as an optimal distribution of aggregate particles to form a matrix structure of aggregates with a particle diameter of 5 mm to 13 mm to form a porosity of 20% or more. Drainable asphalt mixtures have larger voids between asphalt-coated aggregates and aggregates than general asphalt mixtures, so the contact area between the aggregates and aggregates is relatively small, so when an asphalt mixture having the same adhesion or stress is used, the asphalt unit is a binder compared to the general asphalt mixtures. Since the energy load per area is large, the bond between the aggregates is easily broken and the possibility of desorption is very high.

Therefore, in the case of a water-draining asphalt mixture, the viscosity at 60°C requires more than 200,000 poise and at the same time requires more enhanced physical strength.

It can be seen that such high stress is an incomparable high viscosity when comparing that the viscosity of the general asphalt mixture is 3000 to 5000 poise at 60°C.

However, this high-viscosity, high-stress water-draining asphalt mixture has a significantly higher viscosity than general asphalt at 125-135℃, which is a known construction temperature, so the possibility of poor compaction is high. Plastic deformation due to poor compaction and potholes are highly likely to occur. Due to its shortcomings, high-level construction temperature management is important, and many researchers are tasked with securing workability at general construction temperatures while having high viscosity and high stress.

Therefore, as a result of repeated studies of asphalt, which is a binder of water-repellent asphalt mixture, to have higher cohesiveness, SBR-Latex, styrene-isoprene-styrene (SIS), styrene-butadiene-styrene ( Methods of improving the viscosity of asphalt compositions by using synthetic rubber such as styrene-ethylene-butadiene-styrene (SEBS), vinyl ethylene acetate (Ethylene Vinyl Acetate), etc. as a modifier are already known. In addition, many efforts have been made to increase viscosity and increase stress by using synthetic resins such as polypropylene and polyethylene.

Among them, SBS synthetic rubber is most commonly used in terms of economy, but SBS has poor compatibility with asphalt, so when it is mixed by heat melting and left unattended, layer separation occurs. Due to the quality inhomogeneity between the layers of the asphalt mixture, in reality, the quality of the pavement becomes uneven. It is true that there are many problems.

In particular, in order to be homogeneously hot-melt-mixed with asphalt, SBS is relatively homogeneously hot-melt-mixed only if it is kept while stirring at about 180°C or higher for at least 5 hours, so industrially, the SBS-modified asphalt composition is manufactured by using a premixing process It was forced to produce it directly.

Therefore, even now, much effort has been devoted to the study of preventing interlayer separation of SBS-modified asphalt mixtures and shortening the heat-melting mixing process in terms of energy.

Republic of Korea Publication Patent No. 10-0267575 relates to the introduction of a certain amount of a sulfur compound and an alkali metal hydroxide as a layer separation stabilizer to stabilize the layer separation of the SBS modified asphalt composition. Since this SBS modified asphalt composition is a premix type, the modified properties have already been confirmed in the production process and must be supplied to the asphalt concrete plant.

Therefore, it is not only a limiting factor for various grade changes in the Ascon plant, but also has a problem of low low temperature durability.

On the other hand, Korean Patent Publication No. Gen 10-2005-0074414 proposes a high-viscosity drainage asphalt modifier obtained by mixing a tackifying resin and oil in SBS and an asphalt mixture containing the same. The modifier is a plant mix type modifier manufacturing patent, and has the characteristics of a high viscosity modifier to meet the high stress (High Consistency) required characteristic of a water-draining asphalt mixture, but the viscosity at common construction temperature due to the high viscosity is also large. There is a disadvantage in that the sensitivity according to the construction temperature is large, and it is difficult to control the construction temperature because the construction temperature must be slightly high, and thus it is difficult to develop structural strength due to poor compaction due to a decrease in the construction temperature at the installation site.

Therefore, there is a concern that the loss rate (%) of the cantablo may scatter from 11 to 16% in the range of 20% porosity.

On the other hand, the biggest problem that continues in most concrete structures on the road is concrete deterioration caused by freezing and thawing and snow removal. In particular, the freezing and thawing of the concrete structure in the snowy cold region repeatedly acts in winter by freezing and thawing, and the road during snowfall uses a chloride-based snow removal agent to maintain a safe traffic flow. Therefore

Accordingly, structures such as sideways and dykes, heavy components, and bridge railings, which are machine-placed concrete, are directly exposed to chloride and freeze-thaw environments, so that the reinforcement is corroded by surface scaling, exposure of coarse aggregates, and penetration of chloride ions. As such, the premature damage and durability of concrete are rapidly deteriorating, and maintenance costs are greatly increasing.

In addition, if it snows in winter, it is easy to freeze, and if it freezes in this way, vehicle accidents and safety accidents for pedestrians may occur.Therefore, it is necessary to prevent the road from freezing by quickly melting snow accumulated on the road. Recently, a record heavy snow phenomenon occurs frequently due to abnormal weather conditions, so much attention is paid to preventing freezing of roads in winter.

The present invention has been created to overcome the above-described problems, has good durability, plastic deformation, aging, and/or peeling does not easily occur, and at the same time has low noise drainage property, and an asphalt concrete composition that prevents freezing in winter easily. Want to provide.

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.

Here, it is recommended to use a natural asphalt mixture as the asphalt mixture.

The asphalt mixture, in particular, the natural asphalt mixture is not particularly limited as long as it is a natural asphalt mixture commonly used in the art, but preferably straight asphalt, Trinidad lake asphalt, Trinidad epure (Trinidad epure) ) It is preferable to use asphalt or a mixture of at least one or more selected from these, more preferably a mixture of straight asphalt and natural asphalt with a penetration degree of 20 to 40, for example Trinidadrake asphalt and/or Trinidad ePure asphalt. It is recommended to use a mixture of 70 to 80% by weight of straight asphalt having a penetration degree of 20 to 40 and 20 to 30% by weight of natural 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 natural asphalt serves to improve the fluidity of the asphalt concrete composition of the present invention and to increase deformation resistance, sliding resistance, and friction resistance.

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

The natural asphalt is preferably included in the asphalt mixture in an amount of 20 to 30% by weight, 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 exceeds 30% by weight.

It can add elasticity to the asphalt concrete composition.

In addition, the styrene ethylene-butylene styrene is a block copolymer based on styrene and butadiene and has rubber-like elasticity, and while most rubbers are not easily molded due to crosslinking, they can be reshaped into thermoplastic rubber. Therefore, when heated above the Tg temperature of polystyrene, the domains soften and flow with shearing force, and when cooled, the domains can be reproduced again, so it can be easily molded using a thermoplastic molding method.

The aggregate refers to sand, gravel, basalt, pitted stone, basalt, and other similar materials.

Specifically, the aggregate may further include basic malt having an absorption rate of about 0.7% and/or bauxite having an absorption rate of about 5.40%.

Here, it is preferable to use the aggregate having an average particle size of 0.08 to 13 mm, specifically, those having an average particle size of 0.08 mm or more and less than 4.76 mm are referred to as fine aggregates, and those of 4.76 mm or more are referred to as coarse aggregates. The preferred amount of aggregate is preferably 500 to 2,000 parts by weight based on 100 parts by weight of asphalt, and the amount of fine aggregate and coarse aggregate contained in the aggregate is not particularly limited, and thus can be appropriately adjusted as needed.

In addition, when the melt viscosity of polyethylene wax at 140°C is less than 80 cPs, the high-temperature properties are weakened, making it unsuitable as asphalt for road pavement.When the melt viscosity at 140°C exceeds 400 cPs, the viscosity of the asphalt becomes too high to produce asphalt concrete composition and There may be a problem that the process is not performed properly during pouring.

On the other hand, the modified fatty acid used by mixing with the wax serves to improve the moisture sensitivity of the asphalt concrete composition while supplementing the neutralization function of the polyethylene wax.

Specifically, the modified fatty acid is obtained by melt-reacting a fatty acid having 12 to 24 carbon atoms with at least one selected from the group consisting of calcium hydroxide, magnesium hydroxide, zinc hydroxide and zinc oxide in terms of the effect of improving the moisture sensitivity of the asphalt concrete composition. desirable.

In addition, it is preferable that the modified fatty acid has a melting point in the range of 110 to 140°C. When the melting point of the modified fatty acid is out of the above range and is higher than the manufacturing temperature of the asphalt composition, the effect of supplementing the neutralization function and improving the moisture sensitivity cannot be obtained.
