ABSTRACT:
An apparatus for securing reflectors to a road bed. The apparatus deposits a small amount of hot liquid bitumen to the surface of the road and before it cools a reflector is set therein. The apparatus includes a vat for heating the bitumen to about 425.degree. F. An articular heated, insulated dispensing conduit connects the output of the vat to a vertical dispensing valve which when actuated deposits a selected amount of liquid bitumen on the pavement. A pump assembly is connected to the output of the vat and is directed into the dispensing conduit and a dispensing valve is provided at the end of the conduit. The whole system is supported on a trailer which is pulled by a truck. The operator sits in a suspended chair and guides the dispensing valve as necessary to obtain the correct location for the reflectors. A foot switch is provided to actuate the pump assembly and valve in a coordinated fashion.
