Abstract

A mobile paving system (10) is provided that produces paving material while the mobile system (10) proceeds over a surface. The mobile paving system (10) includes an aggregate hopper (12) operable to hold aggregate for use in producing paving material and a mixer (24) operable to mix aggregate with remaining ingredients to produce paving material. A moisture sensor (47) is associated with the aggregate. The moisture sensor (47) is operable to measure moisture in the aggregate and to provide an output representing an amount of moisture measured. A processor (34) is operable to receive an input representing the amount of moisture measured. The processor (34) is further operable to determine a dry weight of aggregate by converting from to dry weight volume used to produce paving material using bulking effect data for the aggregate corresponding to the amount of moisture measured. A mobile paving system (10) is also provided that includes a scale (28) operable to measure and provide a signal representing the weight of aggregate being conveyed by a conveyor (22) to the mixer (24). The processor (34) is operable to receive the signal from the scale (28) and to determine a dry weight of the aggregate being conveyed from the weight measured and the amount of moisture measured.
