Pen Grade Bitumen / Asphalt (60/70, 80/100 penetration) is the core binder material of global asphalt pavement and building waterproof industrial chain, and Linkwin cooperates with large refineries to implement whole-process index monitoring for our asphalt products, strictly controlling penetration value, softening point, ductility, flash point and solubility parameters to guarantee stable grading performance, avoiding excessive hardness brittleness or too soft high-temperature deformation defects of inferior asphalt products. Our petroleum asphalt possesses excellent viscoelastic characteristics at variable temperature conditions: maintaining sufficient flexibility and anti-cracking performance under low-temperature winter environment, while resisting flow deformation and rutting under high-temperature summer traffic load, with strong adhesive force bonding crushed stone aggregate tightly to form stable asphalt concrete pavement structure. Two mainstream penetration grades can meet differentiated engineering design requirements for heavy traffic and medium-light traffic road projects respectively.

In road engineering construction field, 60/70 penetration asphalt is designated binder for expressway, national trunk highway, heavy-load urban arterial road and port heavy-duty pavement asphalt concrete mixing production, requiring high stability against repeated heavy vehicle compression deformation. 80/100 penetration asphalt is more suitable for municipal secondary roads, county and township rural roads, parking lot pavement and asphalt cold patch repair material production. In building waterproof industry, both grades serve as base raw material for SBS modified waterproof roll, self-adhesive bitumen membrane, asphalt waterproof coating and basement anti-seepage primer manufacturing, widely used for roof waterproof, underground basement, bridge deck anti-seepage and tunnel waterproof engineering construction. Many overseas engineering contractors frequently complain about unstable penetration index, poor ductility, easy cracking or rutting pavement failure from low-quality asphalt suppliers; our batch-by-batch full-index testing mechanism fundamentally solves these engineering hidden dangers, ensuring your road and waterproof project construction quality and long-term service life.

Conventional supply modes include bulk asphalt tanker vessel shipment and 180kg iron drum packaging delivery, customized packaging solutions can be arranged according to customer port unloading and production feeding demands to reduce transfer cost. We maintain long-term large inventory reserve to shorten order delivery cycle and avoid project construction suspension caused by asphalt raw material shortage. Complete export inspection documents, batch COA, MSDS and engineering qualification test reports can be issued rapidly to simplify import customs clearance and engineering bidding qualification submission procedures globally. Our professional bulk petroleum product sales team calculates targeted FOB and CIF quotations based on order tonnage and destination port, provides asphalt grade selection technical consultation matched with local climate and engineering design, and supports small batch trial supply before large project framework cooperation. Choosing Linkwin as your asphalt bitumen supplier stabilizes your engineering raw material cost, guarantees project acceptance qualification rate and builds long-term competitive advantage in infrastructure construction market.
