NOVACEL.100 (Loose Cellulose Fibre)

For stone mastic asphalt to be introduced in Malaysia, the main problem is the compatibility of the premix plant with the technology. SMA is currently produced worldwide by using the pelletized cellulose fibre from the German (VIATOP). This fibre has to be mixed in the batch premix plant. There were only several quarry has this specialized premix plant. Majority are still using drum premix plant. To cope with this compatibility issue, we have come out with the loose cellulose fibre. The bitumen supplier (ESSO, etc) will mix this fibre with the bitumen. The bitumen will then can be mixed at the drum premix plant to produce SMA. Thus by using this loose cellulose fibre, all premix plant can produce SMA and there will be no issues of incompatibilities.

NOVACEL.80 (Pelletized Cellulose Fibre)

At present, the most commonly used cellulose fibre stabilising additive is supplied as pellets – fibre is mixed with bitumen creating a pelletized form that may be easily handled and added during mixing. Bitumen-compounded fibre pellets offer several advantages over pure fibre pellets:

  1. Disperse rapidly and completely
  2. No dry mixing time, odourless and dust-free
  3. Not susceptible against humidity
  4. May be dosed automatically
  5. Produce much more homogenous mix
  6. A higher quality of SMA
  7. Increasing mixing outpu

Bitumen-coated fibre pellets are not sensitive against humidity.  The bitumen functions as a range spacer and pelletizing aid during production.  The pellets are added centrally into the mixer, and will disperse quickly and completely.  Compared with pure fibre pellets, much shorter premixing times are required with bitumen-coated fibre pellets. This has the added advantage of reducing stress on the mixer and aggregates.  This allows the batch sizes to be increased resulting in higher throughput.
