Circulating air heating hot in place asphalt recycling machine with 4200L diesel fuel tank
Maintenance method of asphatl road hot in place recycler for pavement thinckness between 40mm and 60mm
4CM ≤recycled thickness≤6CM
1. Original pavement heating(1st layer heating)
v2 same types of heaters keep on heating in echelons, for road surface of 3CM, fast temperature increasing and softening
vSpeed: 3-4M/min
vRoad surface temperature after 1st heater heating: 160
vRoad surface temperature after 2nd heater heating: 180
2. Original pavement milling(1st layer milling)
Front heating tank keeps on heating, full penetration of heat to 3-4cm
Milling loosing: width control, thickness control
Additive adding: precise control of reclaiming agent and asphalt etc.
Mixing: Rear miller fully mixes the pavement mixture and additive
After milling: old bank over 100
Road trough temperature about 90
3. Road trough heating(2nd layer heating)
Heated by the heater with a channel
Base trought temperature after heating: over 180
2cm thickness rapid temperature increasing and softening
4. Milling of the road trough(2nd layer milling)
Front heating tank keeps on heating, full penetration of heat to 2cm
Milling loosing: width control, thickness control
Additive adding: precise control of reclaiming agent and asphalt etc.
Mixing: Rear miller fully mixes the pavement mixture and additive
After milling: old bank about 120 ; road trough temperature about 90
5. New material adding and double layers heating
New material adding: precise control according to the set ratio
Double layer heating: increase the temperature quickly, high efficiency
After increasing the temperature: recycled mixture temperature is about 140
6. Remixing
Aggregate collecting, batch type mixing makes more evenly
Mixed finished mixture temperature is over 140
Before paving the bonding layer will be heated to 90 , realizing “hot bonding”
7. Paving
Paving temperature: over 140
Paving bonding layer temperature:90 or so
8. Rolling
Initial rolling temperature:140
Final rolling temperature: 90
