The photodegradation behavior of a straight asphalt was investigated using a new method "photodegradation test of asphalt binder using pressed thin film samples". Although the photodegradation caused by outdoor exposure is limited to the near surface

A porous elastic road surface (PERS) is superior to drainage asphalt pavement for reducing highway traffic noise. In earlier research and development, for example using a test track, the difference in sound power level (Lw) of cars has been regarded

Focusing on sunlight that has severe effects on the degradation of asphalt pavement during service, this study examined the relationships between the film thickness of asphalt and the states of photodegradation. The results confirmed that thinner fil

Carbon black, used as a reinforcing filler for rubber materials, was evaluated for asphalt binders in pavements. Carbon black added to straight asphalt within 20 wt% caused an increase in the elastic modulus and a decrease in the viscosity of the asp

The components of asphalt binders were separately irradiated with ultraviolet (UV) rays to examine the aging mechanism. The results confirmed that saturates are converted to resins and asphaltenes, resulting in oxygen-containing functional groups, i.

Highway traffic noise is a serious problem in urban areas of Japan, not only for residents along highways but also for highway administrators. Only 13% of urban highways have met the environmental standard for noise. Noise barriers cannot be used as

Using an aging test method, “UV Aging test by pressed thin film samples”, a straight asphalt and a modified asphalt type-II binder were examined for their aging behavior. The results confirmed that this method is effective to simulate the outdoor
