Bitumen 15/25 is penetration bitumen which is blown by hot air and blended by special polymers to keep the penetration in low level and softening point in high level.
Application of bitumen 15/25
Bitumen 15/25 useful for paving of bridge and stiffness asphalt mixes in heavy traffic road construction.
Bitumen 15/25 is used in bituminous mixtures and gives it a high degree of stiffness, developing a good tensile strength and fatigue specifically, according to the pg-3 standard, a high modulus for semi-dense mixtures man means a stiffness modulus> 1 1000 MPA.
