• Marshall Breaking Heads are used to determine deformation under load and flow rate of 4 or 6in (102 or 152mm) hot-mix asphalt samples.
• Lottman Breaking Heads test moisture susceptibility of asphalt specimens.
• Asphalt Tack Bond Shear Strength Apparatus evaluates the shear strength of tack coat between asphalt layers.
• Semi-Circular Bend (SCB) Test Fixture is used to test the strength of asphalt mixtures as well as the low-temperature fracture energy.
