Method for adding foaming agents to pavement aggregate |
摘要 |
In one aspect of the invention, a method for reconditioning a paved surface includes the steps of providing a vehicle adapted to traverse the paved surface; providing a layer of loose aggregate on an underlayer by degrading the paved surface with a degradation element attached to the vehicle; adding a foaming agent to the layer of loose aggregate on the underlayer; and coating a total aggregate surface area by mixing hot asphalt into the loose aggregate and allowing the foaming agent to expand the asphalt.
