                  and durable pavement technologies |   
                |  |  The 
                  Pavement Team is conducting studies on rational and economical 
                  management of pavement, evaluation of pavement performance, 
                  and theoretical pavement structure design method aiming to effectively 
                  utilize Japan's precious assets for a long period of time. It 
                  is also investigating pavement technologies that improve the 
                  roadside environment to construct comfortable and safe cities 
                  and promote recycling. |
