Oxidized bitumen 75/35
Bitumen is produced from petroleum used for the production of asphalt. Oxidized bitumen 75/35 are also used for road construction as well as for waterproofing work.
Uses of oxidized bitumen 75/35
Bitumen is produced from petroleum used for the production of asphalt, chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, also oxidized bitumen 75/25 used for road construction, pavement, crack seal and repairmen, civil works, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, dust-binding, coating, insulating and impregnating agent, make rubber and plastic products.
Engineering properties of bitumen 75/35
The use of bitumen as such, or as a binder in diverse composite materials, is based on its mechanical properties and on the way these properties depend on the loading time and temperature. Bitumen 75/35 are manufactured in a variety of grades with different mechanical properties to meet the demands of road and industrial applications. For the civil engineer and the industrial bitumen user, it is of considerable value to define the mechanical properties of bitumen in terms that are analogous to the elastic moduli of rigid materials. For the structural design of pavements, it is essential to be able to measure and predict the fundamental mechanical characteristics of paving materials. The stiffness modulus of an asphalt depends on the stiffness modulus of the bitumen and the volume fractions of the different mixture components (aggregates, bitumen, air). The stiffness modulus of bitumen is also a suitable parameter for the breaking properties of the bitumen itself and of the asphalts prepared with it
