Factors Affecting the Wheel Rutting on Rural Roads

A. Parsakhoo and S.A. Hosseini

In this study, the wheel ruts frequency and dimensions were investigated according to geographical aspects, longitudinal gradient and surfacing layer of rural roads in Denji Kola village, Mazandaran Province, Iran. Ruts were divided into shallow and deep wheel ruts. Results showed that the ruts length and area were significantly affected by longitudinal gradient of rural roads (p<0.0001). Ruts length in longitudinal gradient class 8-12% was significantly more than other classes (p<0.05). The mean of rut length in this class was 8.19 m. The deep ruts frequency in longitudinal gradient class 0-4% was more than shallow ruts, whereas the number of shallow ruts was more than deep ruts in other classes. The effects of geographical aspect on ruts length (p<0.0001), ruts width (p = 0.0019) and ruts area (p<0.0001) was significant. Although, the ruts width and depth on gravel-grassed surface was more than other surfacing layer, the number of ruts in this surfacing layer was less than bare soil and graveled surfacing layer. Thus, thickness layer of gravel which has been covered by grass is the best mixture for surfacing layer of rural roads.
