3 Paving sections, one lane each

1st paving section with Evotherm, paving mainly at minus degrees,

Asphalt mix temperature in the usual range, near the lower T° limit

2nd paving section with Evotherm, paving at outside T° around 15°C,

Asphalt mix temperature was reduced

3rd paving section with hydrated lime, without Evotherm, paving at

summer temperatures, Asphalt mix temperatures in the usual range

Asphalt production and delivery from 2 mixing plants

Mixing plant #1, no parallel drum, no injection system for liquid additives

Delivered exclusively the mix AC 32 TS with 30 % RAP

Mixing plant #2, with parallel drum & injection system for liquid additives

Delivered the mixes AC 16 BS with 35 % RAP + SMA 8S

B 51 in the area of Prüm
