The instrument measures the roughness coefficient of a joint.
The unit is also designed to test the possible fluage tendency of
bituminous mixtures covering a slope of a dam subject to high sun
radiations. The fluage tendency is the permanent viscous deformation
of a material. The apparatus consists of an inclined adjustable
plane on which the sample is placed.
Inclination angle: 0 – 75°
Max. sample diameter: 100 mm
The plane is slowly tilted until sliding of the upper surface of
specimen on the lower one occurs. The roughness index can be
evaluated from the measured inclination angle.
Dimensions: 270x175x265 mm
Weight: 5 kg approx.
