Outline of Final Research Achievements |
The total length of public roads in Japan is 1.2 million km. In order to appropriate and manage this huge road stock, it is necessary to utilize concrete pavement useful for LCC in the right place. But then, in utilizing concrete pavement, there are many problems such as material deterioration. In this research, For the purpose of developing highly durable concrete pavement, Durability test using environmental test equipment and fatigue test by concrete that mixes fly ash with conventional concrete. As a result, it was clarified that the fly ash concrete pavement proposed in this study is superior in durability and wear resistance to the conventional pavement.

Academic Significance and Societal Importance of the Research Achievements |
本研究は、国内において舗装への適用事例がほとんどないフライアッシュコンクリートを用いた舗装材料について提案したものである。既往の研究ではほとんど考慮されていない凍結防止剤散布によって促進される材料劣化に着目し、その耐久性を定量的に評価している点では、学術的価値は高いものと考えられる。また、提案した舗装材料は耐久性およびコスト面においても有用な材料であることから、道路資産全体にとって大きく寄与するものと考えられる。
