NEW TRENDS IN SPECIFICATIONS AND THEIR APPLICATION TO ASPHALTS PROCESSED IN THE COUNTRY

NEUVAS TENDENCIAS EN ESPECIFICACIONES Y SU APLICACION A LOS ASFALTOS PROCESADOS EN EL PAIS

Current specifications for paving asphalts in force in European countries, and in the principal states and specialised institutions of USA are reviewed. New trends for the classification according to their viscosity at different temperatures are evaluated, taking into consideration that measurements provide a uniform system for evaluating changes in asphalt properties before and after laboratory ageing. The temperature range used for determination is from 4 to 135 degrees C. Locally produced paving asphalts were tested according to the new specifications. The data allow comparison between the current IRAM penetration system for the classification of asphalts, and the new tendency by viscosity. A comparison is included of limiting test values for the remaining tests in current specifications. /TRRL/
