An applicator mechanism for applying a layer of aggregate material on a ground surface comprising an adjustable bracket for mounting the applicator mechanism to a carrying device, a hopper attached to the mounting bracket having a first opening for receiving a supply of aggregate materials said hopper having a second opening for dispensing the aggregate material onto the ground surface, a first shaft attached to the hopper and in communication with the second opening having projections for spreading the aggregate material onto the ground surface through the second opening, a mechanism for driving the first shaft, a second shaft having at least one structure for interacting with the projections in order to control the size or amount of aggregate material exiting the hopper through use of a spring force that adjusts the tension applied to the paddle by way of a handle used to rotate the second shaft, and a mechanism for holding the tension handle in one of several predetermined positions.
A roadway paving system for chipsealing a roadway surface comprising a novel roadway paving vehicle and a novel supply truck is provided. The roadway paving vehicle comprises an asphalt binder material dispensing system and an aggregate material dispensing system. The asphalt binder material dispensing system includes an asphalt tank and a sprayer that sprays a first layer of the asphalt binder material over the roadway surface. The aggregate material dispensing system comprises an aggregate hopper and conveyor mechanism that discharges a second layer of aggregate material over the roadway surface. No wheels run over a freshly laid surface. Supply trucks are linked to the roadway paving vehicle to refill the roadway paving vehicle on a continuous basis without the need of stopping the vehicle.
