[0002] During the construction of roads and bridges, after the concrete pavement is paved and leveled, before the pavement solidifies and hardens, it is necessary to use an indentation mold to indent the pavement. The indentation of the pavement can increase the friction coefficient of the pavement and prevent the pavement from being slippery in rainy and snowy weather, causing safety accidents.
