Abstract:

A study was conducted to determine if sandstone materials could be potentially used as riprap. Nineteen rock samples (16 sandstone samples) were collected in six western states. The rock samples were derived from sites hosting rock art and ruins that were dated between 850 and 1200 A.D. The 19 samples were subjected to a suite of seven rock quality/durability tests. The results indicate that sandstone has remained intact for 800 to 1200 years and that selected sources yield moderate to high quality sandstone materials that may be considered for riprap applications.
