ABSTRACT: This research deals with productivity and cost of rock disintegration and side casting of materials with the use of a hydraulic hammer mounted on a PC 220 Komatsu crawler excavator, which is used on rocky slopes of Hyrcanian forests of Iran. A continuing time study was applied during the road construction. To estimate the volume of rock disintegration, the average end area equation was used. The increasing cut-slope height decreased productivity. The productivity of hydraulic hammer averaged at 5.5 m3h1 for the mean work volume of 5.07 m3m1. The unit cost of the system was 7.7 m3. From the economic point of view a new machine with multipurpose system could be recommended for forest road construction operations in rocky areas.
