BITUMEN 60/70 PENETRATION PAVING BITUMEN GRADE
A grade of 60/70 bitumen means the penetration value is in the range 60 to 70 at standard test conditions which commonly used as a Paving Grade. Bitumen is applicable for the production of hot mix asphalt for bases and pavements and for road construction. Penetration Grade Bitumen supplied by Black Gold Co. is petroleum grade bitumen, produced from fractional distillation of crude oil and vacuum residue (short residue) feedstock. Bitumen is specified by the penetration and softening point test. Designing is by penetration range only. The penetration grade bitumen has a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature-viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability and application temperatures of bitumen.
Black Gold Co. guarantees that the Bitumen Grade 60/70 is produced in compliance to AASTHO M20-70 and ASTM D946/D946M standards and it meets the specified requirements.
