PERFORMANCE TESTS ON BITUMEN AND BITUMINOUS MIXES - Strade & Autostrade - February 2011
A different approach to desining road paving by Pietro Ferrari and Vincenzo Buccino
Three levels of interpretation may be identified in this article. The first, which is the most practical, consists in identifying the limits imposed on the requisites of certain tests, performed on bitumen and its mix, as a function of the minimum and maximum operating temperature, the type and frequency of traffic of the specific road. Deterioration of paving is, in fact, mainly attributable to three things: ruts (permanent deformation due to temperature), fatigue cracking (at moderate temperatures) and cracks due to rigidity at low temperatures...
