3.17 *Asphalt thermometer
Only if equipped with such a thermometer are data about asphalt
temperatures displayed on the indicators.
[A] Asphalt thermometer sensor
General Asphalt compaction can only be done in a special temperature range.
Depending on the asphalt composition, different temperature limits apply
for compaction. The upper (HI) and lower (LO) limits are determined
on site and saved in the system memory. Since the asphalt cools down
continually, the driver has to pay attention to the temperature of the
lower drum. If the machine reaches the temperature limit, this limit (HI or
LO) is displayed in addition to the asphalt temperature.
