Sinkholes are common surface manifestations of the presence of networks of subsurface caverns in areas where the bedrock geology is dominated by soluble rocks such as limestones. Accurate mapping of sinkholes is crucial as they are hazardous to trans

Rockfalls are one of the most common types of slope failures that affect cut slopes along roadways in mountainous regions. The Rockfall Hazard Rating System (RHRS), started in Oregon and adopted by various U.S. states, is used to rate cut slopes with

Rockfall hazard from cut slopes along highways are caused primarily by unfavorable orientations of discontinuities, presence of unconsolidated cobble/boulder deposits, undercutting of strong rocks by weaker rocks, or degradation of weak rock masses.

Seven cut slope sites along Ohio highways containing thick (>10 ft/3.3 m) units of weak rocks (shales, claystones, and mudstones) were selected for investigating slope stability problems and developing design recommendations. Stability problems affec

The slake durability index test is designed to quantify durability of mainly weak rocks. The test is basically tumbling 10 pieces of rocks each weighing 40–60 g for a two ten minute cycles in a water submerged mesh drum (2 mm mesh size). Second cyc
