BITUMEN

Being our core busasphalt-highwayiness for the past 22 years, bitumen both in Bulk & Drummed, is our expertise. Our export volume is substantially high; around 30,000 Mts of Bulk Bitumen and 20,000Mts Of Drummed Bitumen in Pentration Grades of 60/70, 85/100, 40/50, 30/40, Viscosity Grade VG-30 and VG-40, Performance Grade & Cutback. We are the main supplier of bitumen to Bangladesh, India both East & West coast, Indian Subcontinents, Oman as well East & West Africa under one Holding based in UAE, Oman and other Middle Eastern countries.

Our close relationship with major refineries in the Middle East gives us the competitive edge in supplying competitive rates to our customers. All our shipments are accompanied with quality certificates from either of these inspection companies but not limited to Intertek SGS, and Geochem.

Viscosity Grade

Bitumen is graded based on absolute viscosity at 60 ºC or kinematic viscosity at 135 ºC. The SI physical unit of dynamic viscosity is Poise and     kinematic viscosity is expressed in CentiStokes. Pure bitumen has been graded based on AASHTO-M226 and ASTM-D3381 standards.

2. In Bulk

NDT is a leading exporter of Bulk Bitumen from Middle Eastern Refineries. With access to Bulk bitumen carriers floating in the Gulf and and Indian Subcontinent region, we pride ourselves in our capability to load and do all the necessary formalities for a smooth sailing of cargo for our respected customers. The carriers are normally holding a capacity of 2500-5000 mts.

3. Poly Bags:

Bitumen Poly Bags made from (unique poly-alkene compound) have a great advantage by reducing wastage of bitumen. These bags are designed to melt along with the bitumen to form a homogeneous mass at a temperature between 160 and 170 Centigrade, without leaving any unmelted or partially materials, not producing any pollution while being easy to ship and store and at more competitive prices.

Overall features & benefits:
  • Capacity: 300 Kg
  • Withstanding temperature at 130º C± 10º C in the bitumen-filling process.
  • Filling temperature ≤140 º C for the road bitumen
  • Working house temperature ≥ 8 º C
  • Melted completely at 160º C–170º C, while the machine stirred about 20_30 minutes
  • Summer pile up at most for 5_6 layers. Winter pile up for 6_7 layers.
  • The elongation at break is ≥250%
