RIP-RAP PROJECTS NOT AS SIMPLE AS THEY APPEAR

Potential problems for the contractor on riprap work include grading of rock, keyway excavation, and skip placement. Specifications must be read carefully before starting a job. A rock rake is an essential tool in spreading the riprap while permitting undesirable material to pass through. Availability for rock that will break to specifications should be considered. Most keys are dug using a 40- or 50-ton crane with clamshell bucket. If the distance is 30 ft or less from road to eroded area, the backhoe may be used for fast keyway excavation; a crane or dragline bucket will also be needed to dress and comb slopes.
