Warm Mix Asphalt, Long Haul & Compaction Aid
- Thermo+ “Green” Liquid Additive
A new generation vegetable based non-hazardous liquid additive, allowing the production of Warm Mix Asphalt (WMA). Enabling temperature reduction to 110ºC for production and 90ºC for laying and compaction.
- Safe handling, no odour, shelf stable (season to season), pumpable at low temperatures and heat stable.
- Improves aggregate-binder adhesion.
- Suitable for acid included bitumen.
- Thermo+ is a surfactant, this solution doesn’t change the physical properties of the mix design, it only facilitates a performance aspect.
RECOMMENDED DOSAGE:
0.3% Long haul & compaction aid
0.5% Warm Mix Asphalt (130°c mixing, 110°c compaction)
1.0% Ultra Low Mix (110°c mixing, 90°c compaction)
*Dosed into the Bitumen Tank with slight agitation or recirculation, Inline Injection, or added to Binder weighting scale (Batch Plants). For Binder Supplier – dosed into the transport truck during bitumen loading.
Asphalt Performance Enhancer
- BITCEL Cellulose Fibre
- APS-92 Liquid Anti-Strip / Adhesion Promoter
A compressed Cellulose Fiber pellet, used as a binder stabiliser/drainage inhibitor in asphalt production with high bitumen content: SMA, OGPA, asphalt thin layers, high module mixes.
RECOMMENDED DOSAGE (by weight of total asphalt mix)
0.3% to 0.5%
Based on silane nanotechnology chemistry, APS-92 enhances the chemical affinity between aggregate-binder with very low dosage rate.
Odour free, stable in hot bitumen shelf stable (season to season), pumpable at low temperatures.
Reduce/replace hydrated lime dosage in mix design – significant CO2e benefit.
Heat stable adhesion agent for hot cut back bitumen, won’t expire over time
RECOMMENDED DOSAGE (by weight of bitumen)
0.05% – 0.10%
*Dosed into the Bitumen Tank with slight agitation or recirculation, Inline Injection, or added to Binder weighting scale (Batch Plants). For Binder Supplier – dosed into the transport truck during bitumen loading.
Decorative Pavements & Treatments
- Iron Oxide – Natural asphalt colourant
Micronox R01 – Natural Iron Oxide is inherently coloured “Spanish Red”. Supplied in powder format with an average particle size of approx. 1 um.
- Micronox R01 meets tight colour and quality specifications, as required in the Paint and Coatings industry
- Commercially competitve against synthetic colourants with superior UV resistance
- Low CO2e is a naturally occuring product
- Can be blended with synthetic colourants for tailored colours
- Dosed during asphalt production for coloured mixes – bike lanes, bus lanes
Recycled Asphalt (RAP)
- RAP-8V “Green” rejuvenator
A new generation vegetable based non-hazardous liquid additive. A True Rejuvenator, formulated to directly enhance the degraded resin and aromatic content in the oxidised bitumen.
- Pumpable at low temperatures
- Odour-free, heat-resistant and storage-stable in heated bitumen
- Enables reduced asphalt mix production temperatures in applications where reclaimed asphalt is added (Moderate Warm Mix ability)
- Allows for high RAP content Asphalt mixes – over 50%
RECOMMENDED DOSAGE (by weight of RAP)
Typical dosage between 0.10% – 0.15%
*Dosed into the Bitumen Tank with slight agitation or recirculation, Inline Injection, or added to Binder weighting scale (Batch Plants). For Binder Supplier – dosed into the transport truck during bitumen loading.
Bitumen Additives
- BITLINKER – Crosslinking agent for polymer modification
- Natural Bitumen – Natural bitumen viscosity modification/low CO2e mixes
A Cross-Linking agent in granular form, specifically developed to reduce odour and enhance stability of PMB (modified bitumen with SBR/SBS polymers) for long storage periods. It contains chemical catalysts, accelerators and bonding agents.
- Non hazardous
- Faster Digestion Time for PMB producers (less energy input)
- More stable PMB – improves bond between the bitumen and polymer
- Drastically reduce H2S emissions
- Enables reduced SBS dosing
RECOMMENDED DOSAGE (by weight of bitumen)
0.10% – 0.25%
*Dosed in the PMB plant, multiple dose points available
Natural Asphalt/Bitumen, branded AS03, is a naturally occuring substance sourced from Colombia. Used in it’s natural state (no refining process) this products has a drastically lower CO2e footprint than straight run bitumen. Blend with bitumen or sustainable alternatives for bio-binders, enhanced performance coatings or to increase viscosity. Supplied in palletised format (2-4mm granules) for safe storage, handling and ease of processing.
