Abstract: A vehicle for filling potholes and the like in roads with an asphalt-gravel mixture which comprises a wheeled chassis and driving motor, a gravel hopper, a tank for holding liquid asphalt, an extendable and retractable boom, a head applied on the boom for mixing and applying the asphalt-gravel mixture to desired road sites, a first hose carried along the boom and communicating between the hopper and the head, and a second hose carried along the boom and communicating between the tank and the head. Improvements in the disposition of the first and second hoses are provided, along with an improved valve for the gravel hopper, to greatly reduce wear in the apparatus during use and thus to reduce the need for maintenance.
