Of those 55 million tons, about 41.9 million tons (nearly 38 million metric tonnes) contain recycled HMA.Īpproximately 15% of asphalt mixtures in Japan use polymer-modified asphalt binder. According to the National Asphalt Pavement Association of Japan (NAPA), there are about 1,150 asphalt plants in Japan, serving more than 90% of the country and producing about 55 million tons of hot-mix asphalt (HMA) annually. The maintenance of this pavement is accurately controlled. Reason 3: In Japan, the quality of pavement is accurately controlled.Īccording to the Ministry of Land, Infrastructure, Transport and Tourism, in Japan there was a total road length of 341.509 km in 2012, corresponding to 8.050 km to Motorways, 51.237 km to Highways, Main or National Roads, 91.440 km to Secondary or Regional Roads and 190.782 km to others.
