NanoBit-SD+AD. Pellets for Fiber Modifed Asphalt Mixtures + adhesion promoter

Descriptionе

NANOBIT-SD+AD stabilizing agent is intended to be added to the stone matrix asphalt mix at the stage of preparation in order to ensure resistance to the mix separation within the draindown limits during pre-storage in storage bins and during transportation to the paving location, as well as giving an additional effect to the adhesive additive.
NANOBIT-SD+AD – Brown granules up to 8 mm long, 4 mm in diameter.

Dosage:0,3 – 0,5% of the SMA mass.
The average agent effective dosage: :0,4% of the SMA mass.
The amount of agent is selected according to the preliminary laboratory test results for a particular asphalt concrete mix composition.

Main Advantages

Adhesive effect
The stabilizing additive “Nanobit-SD+AD” includes an adhesive additive, which provides improved adhesion of the binder with stone materials in crushed stone and mastic asphalt concrete.

Safe for Human
The stabilizing agent is produced based on purely cellulose fibers and modified bitumen, it does not contain carcinogenic substances and hazardous types of mineral fibers (chrysotile asbestos, etc.).

Producibility and Ease of Use

Due to both low bulk density and high flowability of the granules with maximum diameter of 4 mm, the agent is easily dosed by pneumatic conveying systems. Good flowability and additional talcing prevent clumping and caking of granules during long-term storage and transportation. Full coverage of the fibers with bitumen film eliminates moisture absorption and fiber burning in the asphalt concrete plant mixer.

Perfect Distribution in SMA-Mix

The agent composition ensures complete dissolution of the granules and uniform distribution of the fibers during mixing. The fiber becomes active immediately after distribution in bitumen.

Effective in the Asphalt Production

Nanobit-SD prevents asphalt stains when laying asphalt concrete. Excludes draindown into a vehicle body during transportation of hot asphalt concrete mix. Enhances the asphalt-mixing plant performance, since it requires no additional time for “dry” mixing.

Wide Range

The range of Nanobit-SD stabilizing agents includes several modifications: with the adhesive and temperature-decreasing effect, as well as the complex product with an extra added polymer.

Package and Storage

The agent is packaged in bags with a capacity of 1 m³ or more (big bags), as well as in bags made of polyethylene film. The agent mass in bags shall not exceed 8 kg. The package shall ensure the air tightness, preservation of the agent mass and properties in the course of transportation and storage. The package shall protect the agent from the moisture of the ambient air.

The warranty storage period is 1 year from the date of production. The opened bags are recommended to be used within 24 hours.

Application Technology

The stabilizing granular agent is recommended to be added to the mixer of a modern asphalt-mixing plant onto a heated aggregate prior to feeding or together with mineral powder, providing for “dry” mixing in batch-type mixers for 15-20 seconds.
The stabilizing agent must be evenly distributed in the asphalt binder. It is recommended to use special dosing feeders to inject the additive.
