Abstract. | In Japan various coating technology was researched and developed, which during the process of operation are subjected to large seasonal temperature changes and heavy rainfall. The technology is developed to solve problems of the coating ageing and reduce environmental problems. Draining coatings, absorbing noise. The surface of the coating is more porous than conventional asphalt, it allows water to seep down, then water flows on a sloping impervious surface in the direction of the drain. The coating has a non-slippery surface, even in wet weather. Permeability also suppresses noise from the tires. Water retention coating. Water is retained in the asphalt concrete and the temperature of the coating is reduced due to the evaporation of water. Thermal insulation coating. Special paint is applied to the surface of the coating to reflect infrared rays from the sun and thus reduce the heat which accumulates in the coating. Paint controls the temperature rise on the surface of the pavement, improves the thermal environment in hot weather. For roads in urban areas that are used exclusively by passenger vehicles, reduced geometrical parameters. Lane width was reduced from 3.25 m to 2.75 m. This allows to reduce the cost of construction, especially in the presence of a bridge or tunnel and the construction can be completed in a shorter time. For high-speed roads in rural areas, are proposed to design 2 line roads that can be built with lower cost, compared with the 4 line high-speed roads. In order to ensure mobility of elderly and disabled people, improvements of transport accessibility of sidewalks separated by a dividing strip (lawn). In cities where traffic jams occur almost every day, it is desirable to improve the intersections. But it is difficult because of the impossibility of obtaining land. On the other hand, in rural areas where the population is shrinking, there is an urgent need to open large shopping malls and to have an accessibility to modern medical care, that is, infrastructures that will allow all people, including the elderly and persons with disabilities to live a full life. |
