Heavy oil and vacuum residue were used to obtain road bitumen 50/70 using two different methods of steam distillation at 323–362 °C and by oxidation, a method using packed column at temperature of 211–220 °C. The obtained residues using two methods steam distillation and oxidation are known as non-oxidized bitumen and oxidized bitumen, respectively. The products were […]

What is bitumen 110/30 It is hard grade of oxidized bitumen with softening port 110C + 5 and penetration 30 +5 desimillimiter. Bitumen 110/30 is mostly using in African countries specially Mali and Guinea . How bitumen 110/30 produce? Bitumen is a type hydrocarbon and after destination and remove of hydrogen more carbon will remove […]

Hot melt and cold applied bitumen joint sealant Solvent-free hot melt compositions for use as bitumen joint sealant , adhesives, caulking compounds or the like are produced by intimately blending elastomeric polymers with tackifying resins and plasticizers to obtain products having a hardness at room temperature of at least about 5 on the Shore A Durometer scale while being sufficiently […]
what is bitumen 75/25? It is hard and breakable bitumen with softening port 75C + 5 and penetration 25 +5 desimillimiter. To be able to test softening point of bitumen 75/25, need to use other high temperature fluid instead of water like liquid paraffin or silicone fluid to do not vapour during the test.(water will […]
What is bitumen 75/35 The asphalt 75/35 is hard and breakable bitumen with softening port 75C + 5 and penetration 35 +5 desimillimiter. Scandinavian countries mostly interesting to buy bitumen 75/35 grade and useful for waterproofing at their climate. How bitumen 75/35 produce? Bitumen is a type hydrocarbon and after destination and remove of hydrogen […]
