CORRELATION OF THE RESULTS FROM CREEP TEST WITH THE MEASUREMENTS OF THE WHEEL TRACKING TEST

KORRELATION DER ERGEBNISSE AUS DEM KRIECHVERSUCH MIT DEN MESSUNGEN IM WHEEL-TRACKING-TEST

Creep experiments were carried out with various asphalt mixes on cylindrical samples at a stress of 0.1 mn/m2, at a loading and unloading time of 2 hours each and at a temperature of 25 and 40 degrees C. There is a description of the creep equipment developed at the building laboratory of Rijkswegen. It is shown how certain material factors can be determined from the total deformation, e.g the proportion of reversible deformation, the proportion of irreversible deformation and the velocity of creep. The results have been compared with the measurements obtained in the wheel tracking test. The type of production of the sample pieces is similar for these tests. It was found that the irreversible proportion of deformation for mixtures with an equal make-up of minerals compares well with the measured deformation obtained in the wheel tracking test. A detailed description is given for a mixture with very high porosity which exhibits a deviating behaviour. Finally, a comparison is made with the results obtained in the Marshall test. It is possible to derive a good interrelation between the Marshall flow number and the deformation in the wheel tracking tests. (TRRL)
