Özet

The aim of the study is to determine temporal change of degradations occurring on forest road pavement due to meteorologic factors and determine relations between meteorologic factors and pavement degradations in three month periods for one year. A terrestrial laser scanner (TLS) was used to determine the amount of degradation on forest road pavement. According to the results, mean monthly areal wearing was calculated as 49.6 m(2), mean monthly areal sediment accumulation was calculated as 58.6 m(2), while mean monthly volumetric wearing was calculated as -0.75 m(3) and mean monthly volumetric sediment accumulation was calculated as 0.51 m(3). Also, it was found that, total areal wearing values and total areal sediment accumulation values significantly different in three month periods for one year. In additon to this, volumetric pavement degradation (wearing and sediment accumulation) and areal wearing is positively related to periodic precipitation and precipitation intensity while total areal sediment accumulation is negatively related to periodic precipitation and precipitation intensity in three month periods for one year. Consequently, TLS system can be used effectively in monitoring and evaluating road pavement condition. Also, TLS system is useful and necessary system to obtain high accuracy data for periodic monitoring operation in all kind of engineering structures like forest roads.
