**705.02 Riprap Rock.** Furnish hard, durable, angular rock that is
resistant to weathering and water action and free of organic or other
unsuitable material. Angular rock is characterized by sharp, clean edges
at the intersections of relatively flat surfaces. Furnish rock with
width and thickness of individual rock at least one-third its length
(dimension of longest axis). Do not use shale, rock with shale seams, or
other fissile or fissured rock that may break into smaller pieces in the
process of handling and placing. Conform to the following:

> **(a)** Apparent Specific Gravity, AASHTO T 85 2.40 min.
>
> **(b)** Absorption, AASHTO T 85 4.0% max.
>
> **(c)** Sodium Sulfate Soundness Loss (5 cycles), AASHTO T 104 12%
> max.

> **(d)** Los Angeles Abrasion, AASHTO T 96 50% max.
