The speed of asphalt construction will be faster. After the asphalt is heated, it will have a relatively high viscosity, which is easy to mix with some small gravel and directly spread on the road. Therefore, the efficiency of using asphalt to build roads will be relatively high, and it will not take a long time to open to traffic. If it is relatively long, it may take two or three hours. If it is relatively short, it usually only takes tens of minutes.
