Description

Asphalt-based asphalt composition and water-resistant inner sheet using the same {ASPHALT COPOSITION FOR PREVENTION OF ROOT AND SHEET FOR PREVENTION OF WATER AND ROOT}

TECHNICAL FIELD This invention relates to the field of construction. Specifically, It is related with the sheet | seat and construction methods for domestic water and internal roots, such as a rooftop.

Recently, the urban environment problem caused by desertification, tropicalization, and destruction of ecological space of the city has emerged, and the rooftop greening business of downtown buildings has been actively developed as part of improvement measures and environmental technology development.

Roof greening is an alternative that can satisfy both the ecological problem solving and energy saving of the city at the same time. Its purpose is to utilize the rooftop space that is left in the city which lacks green space.

However, when the existing rooftop space is used, a new planting landscaping facility is installed on the rooftop, causing structural safety concerns.

The most serious of these is the fundamental solution to the leakage problem.

To date, the greening system has not achieved great results due to the absence of technical verification process (load leakage) that can systematically support the requirements of various rooftop recordings.

For this reason, the scope of the domestic materials process for roofing greening of domestic buildings was very limited.

In Korea, although the government support system for the rooftop recording project is in place, the activation of the rooftop recording project is delayed somewhat due to the lack of technical support for each element of the rooftop recording system.

In particular, in the rooftop recording system, domestic demand is pointed out as a basic requirement, but the insufficiency that is handled by the owner and related industries is pointed out as a big problem.

In addition, we apply the domestic method, which is considered to be excellent among the rooftop methods that are generally applied, but this is not an appropriate case for applying a special environmental factor called rooftop recording. There are big challenges to prevent.

As such, domestic construction work for rooftop recording has not been recognized as an important project so that there are relatively few research investment and improvement efforts for technology development in academia and industry, and the backwardness of construction technology, quality and construction management It still does not escape.

However, in the rooftop greening, there is an urgent need for improvement of domestic design and construction method that can take responsibility for the durability of buildings, not just water blocking technology.

Therefore, it is important to maximize the economic value through long-term durability and maintenance of the building, considering that the support of various roofing systems can be expanded only when materials and methods suitable for the characteristics of roofing greening are introduced. Will be the condition.

The present invention has been made to solve the above problems, it is an object of the present invention to propose a waterproofing asphalt composition and a waterproofing waterproofing sheet using the same to implement a rooftop greening system while maintaining the durability of the building.
