PG dei bitumi stradali per il territorio italiano
2010
L’ARTICOLO SINTETIZZA IL LAVORO DI RICERCA SVOLTO DALL’UNIVERSITÀ DI PALERMO PER DEFINIRE - SU BASE TERRITORIALE NAZIONALE - LE TEMPERATURE CARATTERISTICHE DETERMINANTI PER LA QUALIFICAZIONE DEI BITUMI, CONFORMEMENTE ALLE SPECIFICHE SUPERPAVE. NE SONO DERIVATE CARTE TEMATICHE DELLE TEMPERATURE MASSIME E MINIME DI PROGETTO DELLE PAVIMENTAZIONI STRADALI CHE I TECNICI POTRANNO UTILIZZARE PER LA SELEZIONE DEI LEGANTI BITUMINOSI.
Effect of the construction process on the performances of asphalt paving mixes with crumb rubber from scrap tires
2004
This paper presents the results of an experimental study on the use of CRM (Crumb Rubber Modifier) in bituminous mixtures for asphalt pavements, using a Dry Process. Employing experimental methods capable of ensuring that the mixtures obtained and the stress conditions that they undergo in pavements are representative, we clarify some aspects relating to the design and production of mixtures; we also show the effects of the bitumen-rubber interaction on mechanical performances (fatigue resistance and rutting). Among the various factors involved in manufacture, a particular investigation was carried out on the effects of asphalt content, mixing temperatures and mixture compaction. The experi…
