“…7.See Federal Aviation Administration (2020) (Figure 2) showing that USD1 spent for preventative maintenance early in the road pavement life is equivalent to USD4-5 spent later in the pavement life. This phenomenon is also mentioned by Weninger-Vycudil and Litzka (2017) and Kornejew et al (2019).…”

“…A quantification of deferred maintenance, also referred to as maintenance backlog (Gordon (1994); Summers and Glaeser (2017)), is regarded as a necessary input for multi-year budgeting, but it is rarely measured. Defined with reference to a pre-agreed minimum quality standard, the maintenance backlog estimates, also in monetary terms, the amount of unfulfilled maintenance demands to reach such minimum standard at any given point in time (see it applied in Litzka and Weninger-Vycudil (2012); Weninger-Vycudil and Litzka (2017); Fondazione Caracciolo (2018); or Dvorkin (2020)). In fact, this analytical tool provides a compelling argument in the hands of public administration entities when justifying the choice of spending on maintenance against other competing demands.…”

It is puzzling how the optimal maintenance of infrastructure gets so little attention in the public policy debate and in national strategic infrastructure investment plans. In the case of Italy, an information deficit, inadequate strategic planning and governance, and unpreparedness for macro changes affecting infrastructure emerge as critical root causes of neglect. Despite the increasing attention to sustainability (at national, EU and international level), it is not consistently implemented along the life cycle of infrastructure assets, which would entail adequate funding to operate and maintain existing assets. Public administration plays a critical coordination role and must tackle the excessive normative complexity and consequent lengthiness of the authorization processes. Despite some unmet challenges, several ongoing interventions show Italy’s commitment to address some of the issues. Notably, the creation of an integrated repository tracking all the country’s infrastructure projects, or the national guidelines recently issued to rank and prioritize bridge safety interventions.

“…− lygumo (važiavimo kokybės) tyrimai; − pažaidų tyrimai; − laikomosios gebos tyrimai; − rato sukibimo su danga tyrimai. Kelio naudotojams svarbiausi kriterijai yra saugumas ir komfortiškumas (Litzka et al, 2008), todėl kelio dangos lygumas ir rato sukibimas su danga yra aktualūs kriterijai kelio naudotojams. Kelio savininkams ir inžinieriams svarbiausios yra inžinerinės būklės ir funkcinės būklės analizės.…”

“…Austrijoje vertinami tie patys būklės rodikliai -išilginis kelio dangos nelygumas, provėžos, plyšiai ir paviršiaus defektai. Be šių rodiklių, vertinamas rato sukibimo su danga koeficientas, dėvimojo sluoksnio amžius ir vertinama teorinė laikomoji geba, kuri modeliuojama remiantis dangos naudojimo laikotarpio ir dizaino funkcija (Litzka & Weninger-Vycudil, 2012).…”
