On average, 3% of the land area in Japan is covered by roads, and in urban areas, the percentage exceeds 20%. In order to maintain these assets, a whopping several trillion yen is spent every year. In terms of roads and particularly pavement, we, the Road Laboratory, deliberate about what kind of materials should be used, what are the desirable ways to design, construct and make repairs, and therefore what kind of roads are strong, comfortable and safe, reflecting also concern for the environment.
