Asphalt Modifier(Sasobit)
Sasobit제품은 Asphalt 개질재로서 제품 첨가 시 PG를 올려주는 역할을 할뿐 아니라 시공 시 아스콘 온도를 낮추어주어 Warm Mix용 첨가제 역할도 하는 wax제품입니다.
Comparison between Bitumen wax and FT-hydrocarbon wax
- Mixing stage
- >20°C possible decrease in mixing temperature
- Compatibility easy blending
- Reduced blending time
- Energy savings
IMPROVED WORKABILITY
- Placing and compaction
- Lower working temperatures or wider working window
- Reduced fumes
- Lower impact of weather
- Reduced roller compaction necessary
- Faster laying or paving
Asphalt Modifier(Sasobit REDUX)

Asphalt Modifier(Sasolink TX)란?
개질아스팔트 제조시 PG를 올려주기 위해서 사용되는 Polymer(SBS,SBR,LATEX,etc)와 Asphalt의 혼합(Blending) 상분리(Phase Separation)를 줄여주는 Chemical Linking Agent 입니다.

With Sasolink
Sasolink TX의 장점
- Convenient to handle free-flowing powder form.
- Ease of dispersion
- Dispersion time is dramatically reduced from the usual 5 hours dispersion time (for SBS alone) to about 2 hours in total, further no post dispersion stabilization time is necessary.
- Since dispersion cycle times are minimized, Plant throughput is increased
- The viscosity of the modified asphalt is substantially reduced such that it may be easily handled and transported with consequent energy savings.
- A stable modified asphalt blend is produced such that it is easy to handle, transport and use without the bother of phase separation and associated inconveniences.
