The CRT-Prall is designed to carry out the Prall Test according to EN 12697-16A Method A in which a cylindrical specimen of asphalt having a diameter of 100mm and a length of 30mm is tested at a temperature of 5o C. THe specimen is worn by abrasive action over a standard time period of 15 minutes by 40 steel spheres. The loss of volume in millillitres is recorded and reported as the abrasion value.


You can get the Coopers model CRT-PRALL in two versions, 2- and 4-places. That saves a lot of time and gives less wear on the machine.
