Asphalt Modifier

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(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.

  • Without Sasolink

  • 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.
