The invention relates to a main module (10) for a command and reporting system (50), which main module comprises a control unit (16) and a device interface (18) for coupling to at least two command and reporting devices (12, 12.1, 12.2, 12.3, 12.n) in a line topology. The main module (10) also has a bus interface (13) for connecting to a superordinate control unit (11), wherein the control unit (16), by means of the device interface (18), is designed to control at least two command and reporting devices (12, 12.1, 12.2, 12.3, 12.n) separately by means of a command signal (20). According to the invention, the command signal (20) is designed for device-address-free delivery at the respective command and reporting device (12, 12.1, 12.2, 12.3, 12.n) and has a target cell (22) and an incrementable counting cell (24) for this purpose. The invention further relates to a method (100) by means of which the device-address-free delivery is implemented. The invention further relates to a computer program product (80) suitable therefor, to a command and reporting system (50) in which the invention is implemented, and to an automation system (60) equipped with a corresponding command and reporting system (50).

The Present disclosure is related to hot-mix asphalt (HMA) which open new price/performance areas to asphalt cement concrete (ACC) pavement. Equivalent-performing pavement may be made at lower cost, or higher-performing pavement may be made at equivalent-to-prior-art cost. The amendments, recycled asphalt pavement (RAP, and including recycled asphalt shingles [RAS]), and reinforcing fiber (aramid fiber) may be adjusted as described herein to achieve a desired price/performance target.
