Hot wind circulation Hot in place asphalt recycling machine with air temperature 500~700℃

Equipment introduction and constitute of each unit for hot in place asphalt recycler

I. Compposition for ARHR-5120A type hot in-place recycler

It’s composed of 2 units of heating mobile truck, one unit of milling mobile truck, one unit of channel heating mobile truck, one unit of channel milling mobile truck, one unit of double-layer heating mobile truck and one unit of lifting remixing mobile truck, totally 7 separate units.

ARHR-5120A type hot in-place recycler takes diesel as fuel, which is safe and convenient, application of cycling hot-blast heating minimizes aging in construction, meanwhile, scientific and reasonable unit combination, namely multi-step heating and milling at front end with multi-layer mixture heating at back end compensate for defects of insufficient penetration depth of cycling hot-blast and poor mixture heating effect, which greatly improve quality and efficiency during recycling construction.

II Solution for recycled thickness ≤4CM

1. Original pavement heating

3 sets of same type heaters keep on heating in echelons, road surface 4CM, fast temperature increasing and softening
Road surface temperature after 1st heater heating: 160℃

Road surface temperature after 2nd heater heating: 180℃

Road surface temperature after 3nd heater heating: 200℃

2. Heating&milling

Front heating tank keeps on heating, full penetration of heat to 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 temperature is over100℃
Road trough temperature about 90℃ after milling

3. New material adding and double layer 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 over 135 ℃

4. Heating and remixing

Aggregate collecting, batch type mixing makes more even
Finished mixture temperature after mixing is over 140 ℃
Binding course heated to 90 ℃ before paving, realize “hot bonding”

5. Paving

Paving temperature: over 135℃

Paving binding course temperature : about 90℃

6. Rolling

Initial rolling temperature: 130℃

Final rolling temperature: 90℃
