Import Bitumen Grade (60/70) Penetration Bitumen — Buy in Bulk from Supplier in Turkey

Kevser Sanayi supplies penetration grade bitumen 60/70 from Turkey, a standard paving grade used extensively in road construction across temperate climate zones. This grade indicates a penetration value between 60 and 70 decimillimetres at 25 degrees Celsius, measured under standard conditions with a 100-gram needle load for 5 seconds. The material presents as black to dark brown with the high viscosity and colloidal structure characteristic of petroleum-derived bitumen. It dissolves in carbon disulfide and carbon tetrachloride, confirming its hydrocarbon classification. The supplier's source description notes technical specifications and grades are available upon direct request, a common practice for Turkish bitumen exporters handling variable refinery outputs.

The 60/70 penetration grade sits in the medium-hardness range of paving bitumens, softer than 40/50 and harder than 80/100 or 85/100 grades. Standard production involves vacuum distillation of crude oil followed by air blowing or solvent deasphalting to achieve target penetration and softening point values. Typical industry softening point for this grade ranges from 46 to 54 degrees Celsius by ring-and-ball method. Ductility at 25 degrees Celsius typically exceeds 100 centimetres, indicating good elastic recovery under traffic loading. The material exhibits impenetrability to moisture and water, provides electrical insulation, and shows moderate resistance against acids, bases and salts. Adhesion to mineral aggregates remains its most critical performance property, directly influencing pavement durability and stripping resistance.

Road construction contractors, asphalt mixing plant operators, and infrastructure developers in temperate regions form the primary buyer base for Kevser Sanayi's 60/70 bitumen. Applications include hot mix asphalt for wearing courses, binder courses, and base layers, plus road maintenance overlays and patching works. The grade also suits waterproofing membranes, damp-proof courses, and some industrial coating applications where moderate hardness and good temperature susceptibility are required. Turkish bitumen benefits from strategic location between Middle Eastern crude sources and European, African, and Central Asian markets. Buyers should confirm packaging options (typically bulk tanker, steel drum, or polybag), Incoterms, and seasonal availability, as bitumen requires heated storage and transport to maintain workability.

Kevser Sanayi operates from Barbaros Hayrettin Pasa Mah., Nazim Hikmet Blv. No: 84C/57 in Esenyurt, Istanbul, 34515, Turkey. The supplier holds a harbor trust tier classification on the platform, indicating a verified business registration and operational presence, though buyers should note the response rate displays as 0.00 percent with zero average response hours recorded. This suggests limited or no recent engagement through platform messaging, so direct contact verification is advisable. The company profile does not disclose establishment year, employee count, annual revenue, or specific refinery partnerships, so claims about scale or capacity cannot be confirmed from available data.

Kevser Sanayi's listing focuses specifically on penetration bitumen 60/70 for road construction, with an offer to provide technical specifications and additional grades upon request. This indicates a trading or distributorship model rather than confirmed vertical integration with a refinery. The source description contains commodity-level product knowledge rather than proprietary manufacturing claims. Buyers should independently verify the company's supply chain position, whether they source from Tupras (Turkey's dominant refiner) or alternative sources, and their capacity to provide consistent batch quality and documentation. No certifications, quality management systems, or client references are stated in the available profile.
