Greater than 90% of smooth roadways in the united state are made from asphalt, which is created with nonrenewable products such as oil. One means to make leading even more lasting is to reuse old sidewalk. When roadways damage down and require repaving, transport firms can reuse their old sidewalk right into a recyclable product called redeemed asphalt sidewalk, or RAP. This technique minimizes carbon exhausts and saves natural deposits.
