Standards & Grades
We reliably supply high-quality bitumen globally for road construction and industrial projects, ensuring competitive pricing and timely delivery.
Oxidized Bitumen
Air-blown bitumen offers a high softening point, improved elasticity, and excellent durability. It is widely used in roofing membranes, waterproofing systems, pipe coating and various industrial applications where thermal stability and long service life are required.
Bitumen 150/5
Extremely strong grade for industrial and insulation applications
Bitumen 115/15
Superior thermal stability for hard and heat-resistant waterproofing
Bitumen 105/15
Optimum structural rigidity for rainy and damp-proofing membranes
Bitumen 105/35
Tough grade which offers strong thermal and structural stability
Bitumen 90/25
Resilient grade for membranes and protective coatings
Bitumen 90/40
Flexible oxidized bitumen for roofing and waterproofing needs
Bitumen 90/15
Hard and heat-resilient grade for those with industrial waterproofing needs
Bitumen 90/10
Very strong bitumen for insulation of boards as well as pipe coating
Bitumen 85/40
Balanced pliability for improved flexibility and enhanced durability for roofing.
Bitumen 85/35
Reliable grade for general waterproofing and construction applications.
Bitumen 85/25
Heat-stable grade for membranes as well as construction use
Bitumen 75/35
Softer oxidized bitumen for dynamic waterproofing systems
Bitumen 75/25
Calibrated pliability for superior roofing and damp-proof applications

Frequently Asked Questions.
Durable oxidized bitumen for waterproofing, roofing, and long-lasting construction protection, ensuring superior performance and reliable results.
Standards messaging gap: Homepage prominently and repeatedly cites ASTM/EN/AASHTO compliance, COA, and MSDS for its product lines generally and for Bitumen 60/70 specifically (with exact spec numbers). The Oxidized Bitumen page makes zero mention of any standard, COA, or MSDS for oxidized bitumen — an inconsistency in how rigorously each product line is presented, which could read to a procurement buyer as oxidized bitumen being less quality-assured than penetration grade, even if that's not true.
Stat counter formatting mismatch: "Specialized Bitumen Grades" renders as 0+ on the homepage but as plain 0 on the oxidized bitumen page — both appear to be broken/unpopulated JS counters, but the formatting inconsistency itself is a small polish issue worth fixing alongside the underlying bug.
Template artifact links (kodesolution.com/desix/services-gird/, /projects/marketing-webdesign/, /projects/software-development/, /projects/creative-photography/, /projects/apps-development/) are unique to this page in what I checked — these are not present in the homepage's packaging section, which correctly links to /jumbo-bags/, /drums/, /bitutainers/, /bitubox/. This confirms the oxidized bitumen page's packaging block was not updated when the homepage's was, and is worth checking on every other product category page (Cutback, Emulsion, Viscosity, etc.) for the same leftover links.
"Penetration GradeS" heading appearing on a page entirely about oxidized (non-penetration) grades is a direct topical contradiction within the page itself and should be treated as the highest-priority single fix, since it actively confuses both users and topical-relevance signals for search/AI systems.
________________ Priority order if fixing sequentially
Fix the four broken packaging tile links and the off-domain "Find Your Solution" link (1.9, 1.8) — these actively send buyers off-site or to dead ends.
Remove/correct the "Penetration GradeS" mislabel (1.4).
Add a per-grade specification table with standards references (4.1, 4.2) — this single addition improves AEO, GEO, and E-E-A-T simultaneously.
Rewrite meta description and grade tile copy (1.2, 5.1).
