After slipform paving and surface anti-sliding structure of cement concrete pavement are completed, it should be maintained in time. In the early stage of maintenance, in order to prevent the cement concrete from being exposed to the sun and rain, it is advisable to spray curing agent or use plastic film for pavement maintenance. You can also use sprinkler maintenance methods such as covering old sacks, straw bags, straw curtains and straw that can store water (but not too early, otherwise there will be traces of sacks on the road). For large-area, high-speed slipform paving, the methods of confining water, covering sand and sprinkling water are not suitable.
