Abstract
A chip sealing train for use in carrying out a chip sealing operation on a roadway using foamed asphalt cement includes a chip supply dump truck, an asphalt cement supply truck and a chip spreader. The chip spreader includes a receiving hopper for receiving stone chips from the raised dump bed of the chip supply dump truck and a spreader assembly which is adapted to dispense the stone chips onto the roadway. The chip sealing train includes a water tank and a foam dispersal assembly. The foam dispersal assembly includes a foaming chamber, an asphalt cement supply line that is in fluid communication with the asphalt cement supply truck and the foaming chamber, and an asphalt cement pump for pumping asphalt cement from the asphalt cement supply tank into the foaming chamber. The foam dispersal assembly also includes a water supply line that is in fluid communication with the water tank and the foaming chamber, and a water pump for pumping water from the water tank into the foaming chamber. A spray bar is adapted to dispense foamed asphalt cement from the foaming chamber onto the surface of the roadway in front of the spreader assembly.
