Abstract: A method includes determining, using a processing device, a set of observations from coolant data, the coolant data being received from one or more sensors in an environment associated with a coolant. The method further includes determining, using a machine learning model and the set of observations, a contamination level of the coolant. The method also includes initiating an operation, using the processing device, responsive to determining the coolant contamination level.

Abstract: A hopper insert is provided for a road paver. The hopper insert includes a funnel-shaped base body formed by four side walls. The upper side of the base body is open and at least three of the side walls extend inwardly therefrom to a bottom opening. One of the side walls includes a side outlet which is open to the bottom opening. The base body or the side outlet is adjustable in a width direction extending along the side wall containing the side outlet. The hopper insert is removably disposed in an integrated hopper of a road paver. The integrated hopper includes a rear wall with a gate that is adjacent the side wall of the hopper insert containing the side outlet. The side outlet is adjustable in the width direction to correspond to the width of the gate.
