Abstract: There is described a computer-implemented method for handling a mixer truck containing a return concrete load. The method generally has: accessing return concrete data including at least quantity data indicative of a quantity of the return concrete load contained in the drum of the mixer truck and composition data indicative of a composition of the return concrete load contained in the drum; accessing ticket data including job tickets each including a ticket specification; establishing a list of eligible job tickets by comparing the return concrete data to each job ticket, and including a given one of the job tickets in the list contingent upon finding a match between the ticket specification and the return concrete data; and generating a signal indicative of the established list of eligible job tickets.

Abstract: There is described a method of operating a concrete mixer truck having a rotary drum configured to receive fresh concrete and an on-board computer. The method generally having: performing an unloading operation including unloading a first portion of the fresh concrete from the drum at a job site, a second portion of the fresh concrete remaining in the drum as return concrete subsequently to the unloading operation; the computer acquiring a first signal indicative of a presence of fresh concrete in the drum; the computer acquiring a second signal indicative of termination of the unload operation; the computer activating an indicator perceivable by a driver of the concrete mixer truck contingent upon receiving both the first signal and the second signal, the indicator signalling a presence of return concrete in the rotary drum to the driver.

Abstract: There is provided a method of coordinating the actions of a plurality of trucks using at least one beacon sending a first signal including a first signal beacon identifier to a first truck device of a first one of the trucks, the at least one beacon sending a second signal including a second signal beacon identifier to a second truck device of a second one of the trucks, a coordinating computer receiving a first input from the first truck device, the first input including at least the first signal beacon identifier and a first truck identifier, receiving a second input from the second truck device, the second input including at least the second signal beacon identifier and a second truck identifier, determining a queue order for the trucks based on the first input and the second input, and transmitting directive signals to the trucks based on the queue order.
