1. A system for monitoring a productivity of a paving machine, the system comprising:
a load monitoring device located on a mount between a traction device and a frame of the paving machine, wherein the load monitoring device is configured to provide a signal indicative of a change in a load on the frame of the paving machine; and
a controller communicably coupled to the load measuring device, the controller configured to:
receive the signal indicative of the change in the load on the frame;
determine a sum value of the change in the load on the frame based on the signal received each time when a material is delivered to the paving machine, wherein the signal indicates an increase in the load on the frame; and
determine a weight of the material provided to the paving machine based on at least the sum value of the change in the load.
