Description

6cm depth single lane hot in place recycling equipment for road maintenance

?

Description

ARHR-5120A type hot in-place recycler takes diesel as fuel, being 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.

?

Combination mode for ARHR-5120A type hot in-place recycler

It’s composed of 2 units of heater, one unit of milling machine, one unit of channel heater, one unit of channel milling machine, one unit of double-layer heater and one unit of lifting remixer, totally 7 individual units.

?

Characteristics of the equipment

1, Minimization of aging in construction, low-temp.and tender heating method, ensuring pavement surface temp. less than 195℃;

2, Multi-step heating and milling method effectively solve problem of insufficient heat penetration, and realize non-break and no gray material when milling;

3, Realizing accurately and uniformly adding for regenerant, asphalt and new asphalt mixture;

4, Realization of double-layer heating for mixture effectively increases heating area and greatly improve mixture heating effect.

5, Adopting infrared heating technology, positioning heating toward road trough in front of paver, realizing heat connection.

6, Adopting batch type mixing technology, to make recycling mixture mixing sufficiently and uniformly.

7, Asphalt smoke and gas caused by agitation on certain position would be treated for a more cleaning construction environment.

8, Recombination of function makes a smaller size of units for better mobility and transportation.

9, Loading device realizes automatic lifting and falling, crane is not required when units moves in or out.

Process node control | Original pavement heating | Original pavement milling |
Heating mode | Heat source temp. | Pavement temp. | Trough bottom temp. after heating | Degree of aging | Milling mode | Bank condition |
Infrared heating | 900℃～1100℃ | 250℃～300℃ | 100℃ | serious | 4-5cm whole layer milling | 110℃,no broken, no gray material |
Normal hot air circulation | 350℃～550℃ | 190℃～200℃ | 70℃ | light | 4-5cm whole layer milling | 90℃,light broken,there is gray material |
Our layered hor air circulation | 350℃～550℃ | First layer | 160℃～180℃ | 100℃ | light | Single layer, 2-3cm layered milling | 110℃, no broken, no gray material |
