Transport infrastructures interact closely with the surrounding environment, significantly influencing design and management criteria.

Le infrastrutture di trasporto interagiscono strettamente con l’ambiente circostante, influenzando in modo significativo i criteri di progettazione e gestione. Le strade in particolare necessitano di un’adeguata resistenza passiva agli agenti atmosferici e alle variazioni di temperatura. Al giorno d’oggi le soluzioni tradizionali possono risultare inadeguate a causa dell’aumento della frequenza e dell’intensità degli eventi climatici estremi (forti piogge, alluvioni e caldo anomalo). Inoltre la scelta dei materiali per la realizzazione delle strade può contribuire attivamente amplificando gli effetti negativi, in particolare per quanto riguarda il fenomeno delle isole di calore e il drenaggio dell’acqua piovana. Il presente elaborato analizza le principali problematiche legate all’impiego di schemi e materiali tradizionali, esamina il quadro normativo attuale e le più recenti direttive in materia ambientale. In conclusione vengono esaminate le nuove tecnologie a disposizione e le prospettive future.

Abstract
Transport infrastructures interact closely with the surrounding environment, significantly influencing design and management criteria. Roads, in particular, require adequate passive resistance to weather conditions and temperature fluctuations. Nowadays, traditional solutions may prove insufficient due to the increasing frequency and intensity of extreme weather events (such as heavy rainfall, flooding, and abnormal heat). Moreover, the choice of materials used in road construction can actively contribute to amplifying negative effects, especially in relation to the urban heat island phenomenon and stormwater drainage. This paper analyses the main issues associated with the use of traditional design schemes and materials, reviews the current regulatory framework, and discusses the most recent environmental directives. Finally, it examines the new technologies available and outlines future perspectives.| File | Dimensione | Formato | |
