道路舗装用PAN繊維改質アスファルト:優れたわだち掘れ抵抗性、ひび割れ抑制性、耐老化性、および疲労性能

Why Asphalt Pavement Needs Fiber Modification Asphalt pavement is widely used in road construction because it gives a smooth driving surface. It can reduce driving noise. It can improve riding comfort. It can also reduce tire wear compared with some rigid pavement surfaces. But asphalt pavement also has clear problems. Under high temperature and heavy traffic, asphalt can become soft and deform. This can create rutting, shoving, and permanent deformation. Under low temperature, asphalt can become brittle. This can cause cracking. Under repeated traffic load, asphalt pavement can also develop fatigue damage. These problems reduce road service life. They also increase maintenance cost. For highways, airports, bridge decks, urban roads, […]
