MODIFIED MARSHALL TEST FOR DETERMINING THE SUSCEPTIBILITY OF BITUMINOUS MIXTURES AT ROAD SERVICE HIGH TEMPERATURES

This work attempts to study the behavior of bitumens when forming bituminous mixtures at high temperatures of service in highway pavements. The results corresponding to the previous experiences that have been the base of the present work formed part of the Spanish National Report sent to the 3rd International Symposium, RILEM, Belgrade 1983. A modification of the Marshall test has been used to allow the determination in a simple way, of the rheological properties of the bituminous mixtures, in the interval of the temperatures in which the most important characteristics of these materials are manifested fundamentally when employed in highway pavements. A temperature of about 60 degrees C represents this critical zone in which the phenomena of plastic deformation of these mixtures are produced, and constitute one of the actual and most important problems to set up in the bituminous materials.
