Description

Low noise drainable asphalt concrete composition containing SBS and construction method using the same {Low Noise Asphalt Concrete Compositions Using Stylene Butadien Stylene and Constructing Methods Using Thereof}

The present invention relates to a low-noise, drainable asphalt concrete composition containing SBS and a construction method thereof. More specifically, it relates to a low-noise, drainable asphalt concrete composition containing SBS that has low noise drainage using SBS and a construction method thereof. .

In general, asphalt is a black or dark brown solid or semi-solid thermoplastic material that is very complexly composed of thousands of types of polymer hydrocarbons (C-H) containing organic compounds and trace amounts of inorganic compounds, and has the characteristic of gradually changing into a liquid state when heated.

The asphalt is divided into types such as 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 binding material or adhesive material because it has excellent adhesion and adhesion to mineral materials. It is also used as a waterproofing material because it does not dissolve in water and is impermeable. The viscosity can be changed depending on the purpose of use. Its application range is diverse and it is used for various purposes such as road paving, waterproofing, general industrial purposes, and agricultural purposes.

Meanwhile, drainable asphalt concrete was first constructed in the 1950s in the UK to prevent hydroplaning on runways, and in the 1980s, high-viscosity modified asphalt was developed in Japan to improve durability due to the high porosity (open asphalt), a disadvantage of drainable asphalt. , it was expanded widely to compensate for its shortcomings, and since 2001, the use of drainable asphalt has been mandatory on all highways and general roads in Japan unless there are special reasons.

In Korea, since the first test pavement was installed on the Gyeongbu Expressway in 1997, the Ministry of Construction and Transportation designated the drainage pavement method as a new technology in 1999 and is gradually expanding its application. However, problems such as aggregate detachment, plastic deformation, and potholes still occur, and technological supplementation is urgently needed. This is the situation.

Drainable asphalt has a porosity of more than 20%, which allows rainwater to permeate during rainy weather through the formed pores and prevents rainwater from accumulating on the surface of the road. Compared to general asphalt, rainwater scatters less while driving, and the formation of spray is small, ensuring better visibility when driving. In addition, the effect of preventing traffic accidents is large because hydroplaning is small and the effect of preventing the car from slipping on the road surface is large, and the formed air gap absorbs road surface friction noise caused by the air pumping phenomenon between car tires and the road surface that occurs during driving, so it is better than existing roads. It is a high-performance asphalt that can reduce noise by about 4 to 8 dB.

However, due to the structural mechanics of drained asphalt concrete, the contact area between aggregates due to high voids is small, so the aggregates are easy to separate and have low durability compared to general asphalt concrete.

In addition, impervious asphalt concrete is essential to prevent ground subsidence caused by rainwater permeating into the basement in the base or middle layer, and a drainage layer is laid on top of this to form an impermeable layer by applying tectonic coating.

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

Therefore, in the case of drainable asphalt mixtures, a viscosity of 200,000 poise or more at 60°C is required, and at the same time, more enhanced physical strength is required.

Such high stress can be seen as an incomparably high viscosity when comparing the viscosity of general asphalt mixtures of 3000 to 5000 poise at 60°C.

However, this high-viscosity, high-stress drainage asphalt mixture has a significantly higher viscosity at the known construction temperature of 125 to 135°C than general asphalt, so there is a high possibility of poor compaction, and there is a high possibility of plastic deformation and potholes due to poor compaction. Because it has disadvantages, high-level construction temperature management is important, and many researchers are tasked with researching how to secure constructability at general construction temperatures while maintaining high viscosity and high stress.

Therefore, as a result of extensive research to improve asphalt, which is a binder for drainable asphalt mixtures, with higher cohesive strength, SBR-Latex, styrene-isoprene-styrene (SIS), and styrene-butadiene-styrene ( Methods for improving the viscosity of asphalt compositions by using synthetic rubber as a modifier such as styrene-ethylene-butadiene-styrene (SEBS), Ethylene Vinyl Acetate, etc. are already known. This is true, and many efforts have been made to increase viscosity and stress by using synthetic resins such as polypropylene and polyethylene.

Among them, SBS synthetic rubber is the most widely used in terms of economic efficiency, but SBS is not compatible with asphalt, so when it is mixed by heat and melted and left, layer separation occurs, and the quality of the pavement is realistically heterogeneous due to the quality heterogeneity between layers of the asphalt mixture. It is true that there are many problems with this.

In particular, in order to be homogeneously heat-melted and mixed with asphalt, SBS must be kept at a temperature above 180°C and stirred for at least 5 hours to be relatively homogeneously heat-melted and mixed. Therefore, industrially modified asphalt compositions are manufactured by asphalt manufacturers through a premixing process. I had no choice but to produce it myself.

Therefore, much effort has been put into researching the prevention of interlayer separation of modified asphalt mixtures and shortening the heat melt mixing process in terms of sexual energy.

Republic of Korea Publication Patent No. 10-0267575 relates to adding a certain amount of sulfur compound and alkali metal hydroxide as a layer separation stabilizer to stabilize the layer separation of the modified asphalt composition. Because this modified asphalt composition is a premix type, its modification characteristics have already been confirmed in the production process and it is bound to be supplied to the asphalt plant.

Therefore, not only is it a limiting factor in various grade changes in asphalt concrete factories, but there is also the problem of low low-temperature durability.

Meanwhile, Republic of Korea Patent Publication No. Zen 10-2005-0074414 proposes a high-viscosity drainage asphalt modifier mixed with SBS and an adhesion-imparting resin and oil, and an asphalt mixture containing the same. The patent for the modifier is a patent for manufacturing a plant mix type modifier, and has the characteristics of a high viscosity modifier to meet the high stress (High Consistency) required for drainable asphalt mixtures. However, due to the high viscosity, the viscosity at common construction temperatures is also high. It has the disadvantage of being highly sensitive to construction temperature, and because the construction temperature must be somewhat high, it is difficult to control the construction temperature, making it difficult to develop structural strength due to poor compaction due to a decrease in construction temperature at the installation site.

Therefore, there is a risk of scattering as the cantabro loss rate (%) is 11 to 16% in the porosity range of 20%.

The present invention was created to overcome the above-described problems, and provides an asphalt concrete composition that is durable, does not easily cause plastic deformation, aging, and/or peeling, and has low noise and drainage properties.
