dc.description.abstract | Due to the insularity of Taiwan region, she is always in lack of natural resources. Sand and stone are the basic materials for constructions have been mined over a long period of time and for considerable quantities. For the time being, except for the eastern riverbanks, almost all riverbanks in the western region that supplies sand and stone materials have exhausted. Therefore, effective control and use of sand and stone resources have become the primary task of construction management.
As regards the asphalt concrete used for pavement constructions, the components of its plane leftovers still remain sand, stone, and asphalt cements. The plane leftovers of asphalt concrete can be recycled with the use of hot-mixed regeneration technology, and the technology produces hot-mixed regenerated asphalt concrete, which can be used as road pavements, so we can achieve the purpose of reducing the usage of sand and stone resources.
Due to relative government policies and legislations, and the defectiveness of the establishment of the model for quality verification, it discouraged the faith relative organizations to the usage of hot-mixed regenerated asphalt concrete, although the hot-mixed regeneration of asphalt concrete plane leftovers has been fully proven in the relative technologies. Therefore, the usage of hot-mixed regenerated asphalt concrete have not yet been put into effect.
As to establish the confidence of relative construction sponsoring organizations, this research will begin with two aspects. First with the planning of contract making strategies, then with the establishment of the model for quality verification, we may effectively popularize the usage of hot-mixed regenerated asphalt concrete. After that, the sand and stone resources that are gradually decreasing can be fully reused to decrease the pressure of the lack of sand and stone resources, and achieve the purpose of reduction of construction by-products. | en_US |
