Complex verification of the road pavement serviceability

Anssi Lampinen, Laszlo Gaspar

Research output: Book/ReportReport


As a part of the scientific-technical co-operation between Finland and Hungary problems connected with pavement serviceability and pavement condition evaluation have been dealt with. The following themes were dealt with in the jointly drawn up report: evaluation of pavement serviceability, measuring methods and equipments for structural serviceability of pavements, road data bank, long-term observation of roads and pavement distresses. The Hungarian report states that there has been an intensive research work on the themes in Hungary during the last decade. Two basic levels of pavement evaluation types are briefly introduced: a detailed condition rating primarily for research purposes and a rapid, less detailed condition rating for operational purposes. The main characteristics of the sufficiency rating carried out on the total Hungarian state highway network are summarised. The Hungarian road data bank is just now under development. A long-term observation of selected highway sections has been carried out in Hungary since 1972. The method is explained. A catalogue has been worked out for Pavement deficiencies in 1980. Some retails of this catalogue are introduced here. The Finnish report presents a background of serviceability measurements in Finland. It states that pavements serviceability evaluations are carried out for several reasons: construction of a new road, characterisation of load carrying capacity of the road network, need for repaving, evenness of new pavement. The following serviceability measurement methods are introduced briefly: longitudinal evenness measurements, wear measurements, cross fall characterisation, pavement failures and visual inspections. The Finnish road data bank was started in 1972 and includes at the moment 37 different data types. A long-term observation of 50 highway sections was started in 1979 and has been carried out since then. The use of studded tyres affects the wear resistance and the serviceability of pavements in Finland. At the moment there are already apparatuses for the evaluation of pavement serviceability that are easy to use and they have enough capacity even for a systematic evaluation of the road network. The systematic evaluation of road condition has become an important factor when considering the maintenance and the construction work. The road data bank is an important factor in this work and in it data about serviceability ought to be included.
