Abstract
Obnavljanje cestovnih kolnika s obzirom na sustav održavanja
Highlights
Highway networks of industrialized countries are nowadays generally completed, and so only some city by-passes or expressway sections still await construction
In addition to professional routine maintenance of roads, the design and construction features of structural pavement rehabilitation activities are of major importance, contributing greatly to an efficient and economic management of road pavements
A well-functioning Pavement Management System (PMS) can inter alia be utilized for optimum timing of pavement condition improvement activities on road sections [2]
Summary
Highway networks of industrialized countries are nowadays generally completed, and so only some city by-passes or expressway sections still await construction. The utilization of standard rules for selecting a rehabilitation strategy (treatment) allows adoption of a consistent approach to planning, and definition of activities, making up the road administration practice [3]. This helps to ensure that funds are spent to the greatest effect and that each road receives a fair share of the budget. The efficiency levels of various pavement rehabilitation methods basically differ depending on a lot of parameters including initial pavement and sub-grade condition, quality of basic materials to be used for pavement rehabilitation, level of rehabilitation design (selection of an "optimum" intervention method), quality of construction, level of timeliness and professionalism in maintenance activities, traffic load characteristics, and environmental load. Since the majority of these trial sections were rehabilitated at least once over the past 25 years, the actual characteristics of the Hungarian road management practice can be collected and scrutinized, so as to utilise this information in road management
