The Direct Tension Tester – DTT Equipment is a complete instrument to assess the static stiffness and failure properties of asphalt binders at low service temperatures, as per AASHTO T 314 standard. butterfly” to a stretch at low temperatures (+6°C to -36°C) in order to obtain a tensile strength. This equipment is used after characterization in the BBR (Bending Beam Rheometer) equipment, to evaluate modified binders that may have a stiffness greater than that desired, but which may not show a tendency to crack during contraction, due to their deformation capacity at low temperatures, as it has sufficient ductility.

Stratura is a pioneer in high-performance asphalt materials technology, which has the Direct Tension Tester – DTT Equipment, an important tool that enables engineers and consultants to anticipate decision-making in relation to design and construction methods, such as:

– Evaluate the best binder to be used at low temperatures without thermal cracking, predicting the temperature at which thermal cracking will occur on the road.
