In this study, forest road construction techniques, environmental damages, cross sections and productivity by using hydraulic excavator and bulldozer were investigated in forested lands in Antalya (Aykiricay region) and Eskisehir (Seyitgazi region) province in Turkey. Besides, cross sections built by using bulldozer and excavator were compared considering differences in fill-slope and cut-slope sections. Maximum length of fill slope for bulldozer and excavator were found to be 17 m on 80% slope gradient and 11 m on the same slope gradient, respectively. The unit costs of bulldozer and excavator were calculated as $21.8 per meter and $8.5 per meter, respectively. Productivity of bulldozer and excavator were found to be 105.8 m3/h and 66.2 m3/ h, respectively. The wounded rates of trees under the forest road in Aykiricay and Seyitgazi are found 23% and 40%.
