Bitumen 15/25 useful for paving of bridge

Bitumen 15/25

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.

Why contractor choose this grade?

Selection of the appropriate binder is a very important aspect in the asphalt mix design process. Usually binder grades are affected by temperature and traffic loading expected in service, with stiffer binder grades selected when heavily loaded or slow-moving vehicles are expected. However, utilisation of stiffer binders often results in stiff mixes that have workability related issues since they are not easy to place and compact to the desired density. Furthermore, sometimes stiff binders are modified with polymers that further increase their viscosity hence substantially negatively impacting on workability at a given temperature.

Application of bitumen 15/25

This type of Bitumen 15/25 useful for paving of bridge and stiffness asphalt mixes in heavy traffic road construction.

It 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.
