Increase RAP with Astec ReMix CCPR System
BY AsphaltPro Staff
Through cold central plant recycling (CCPR), state departments of transportation (DOTs) and other agencies can use more recycle material while reducing greenhouse gas emissions associated with traditional mix production operations. The Astec ReMix™ CCPR system is a modular plant, designed to help producers use up mountains of recycled asphalt pavement (RAP) stockpiles at their facilities. It employs a “cold” foaming process.
By reusing RAP materials and mixing them at ambient temperatures, the system reduces the need for both virgin aggregate and energy for heating the mix. This conserves both natural resources and lowers carbon emissions.
The Astec ReMix system has a nominal production rate of 300 tons per hour production. It offers a range of modular configurations. From highly portable setups to maximum production configurations capable of handling large-scale road construction, the Astec ReMix CCPR provides producers with options.
The system comprises the following components:
- A core load with a trailer chassis;
- 300 TPH pugmill;
- Feed conveyor;
- Controls system;
- Water line connection;
- Shore power connection;
- Water pump and metering system; and
- Either a foamed asphalt injection system or an asphalt emulsion injection system.
The system features an intuitive user interface to enhance productivity and reduce the learning curve for operators. The touchscreen and controls are located on a panel at ground level and offer real-time trending and diagnostics. The controls include recipe memory, automatic material proportioning, and start/stop capability and speed control (where applicable) for plant motors.
The free water system includes a 180-gallon-per-minute pump with a 3-horsepower variable speed electric drive, flowmeter and valve. The cleanout system features a 2-gallon-per-minute cleaner pump, 10-gallon spray bar recirculating cleaner system and 5-gallon water line cleaner system. The pugmill is a twin-shaft design mixing box with AR steel liners featuring an electric motor with v-belt driven gear reducer.
The first two units are in testing with producers and the design is available for purchase.
