Screed -- Continued.
The screed uses an electric heat system powered by an on-board generator. Electric heat provides a safety
measure over propane in wartime and during operations in other hazardous environments. The hydraulically-
controlled screed extends to 16 ft (4.9 m) and bolt-on extension boxes (one on each side) further extend the
screed width to 20 ft (6.1 m).
While the majority of BMPM controls are available to the main operator, screed functions can be manually
adjusted by screed control operators stationed on the screed platform at the rear of the BMPM.
Sonic Auger Sensors
Figure 2. Sonic Auger Sensors.
The BMPM uses sonic auger sensors (Figure 2, Item 1) to control the amount of paving material flowing to the
screed and screed extensions when operating in automatic mode. Each auger and conveyor is independently
controlled for maximum material management on any given job requirement. The screed control operator has the
capability to switch the augers from automatic to manual at any time during the paving operation.
