Asphalt and Bituminous
w+b offers a wide range of testing machines for different asphalt and bituminous materials tests. Each system can be individually configured according to your testing needs for an optimal solution.Bitumen is a mixture of organic liquids that are highly viscous, black, sticky, entirely soluble in carbon disulfide and composed primarily of highly condensed polycyclic aromatic hydrocarbons..
Asphalt is a composite material commonly used for construction of pavement, highways and parking lots. It consists of asphalt binder and mineral aggregate mixed together then laid down in layers and compacted.
In this section you find a wide range of testing machines for the determination of the strength, stiffness, fatigue resistance, marshall tests of asphalt and bituminous mixtures.
In addition we offer a wide range of testing equipment for the determination of binder content, internal friction, cohesion, consistency, softening point, viscosity, quality of aggregates, level of compaction a.s.o. of bituminous and asphalts.
All testing machines and equipment conform to the relevant international standards as EN, ASTM, AASHTO and other corresponding national standards. The main field of application are bituminous and unbound material testing including conducting of uniaxial testing and research on bituminous mixes to determine resilient modulus, Poisson's ratio, indirect tensile creep and strength, dynamic modulus, tensile strength, phase angle, and flexure fatigue. Further triaxial asphalt, soil resilient modulus, dynamic foundations design, liquefaction, and conventional tests are performed.
Cold Bending Test Device TD-KB for the Determination of flexibility of roofingmaterials at low temperatures
The TD-KB series is designed for the determination of flexibility of bitumen sheets at low temperatures according toEN 1109 & SIA 281.
These easy-to-use units allows to perform tests in the temperature range from -45°C to +200°C and offers the pre-temper of up to 6
specimens at the same time.
The lower bending distance is adjustable and all parts that submerge into the cooling liquid are made from Cr-Ni Steel.
