STONE FOR RIPRAP

A. Stone grouted riprap shall consist of field stones furnished in broad flat shapes to the maximum extent practicable. All stone shall be hard, sound, durable, highly resistant to weathering and shall be suitable as protection material for the intended purpose.

B. Samples of the stone material proposed for use in the Works shall be submitted to the Engineer for approval prior to its use in the Work.

C. The minimum apparent specific gravity shall be 2.5 and the maximum absorption shall be 6% when tested in accordance with AASHTO T85 – 85. The stone shall have an abrasion loss not greater than 45% when tested in accordance with AASHTO T96.

D. Unless otherwise indicated on the drawings or directed by the Engineer, stones for grouted riprap shall generally weigh between 10 and 50 kg with at least 60% weighing more than 30 kg.

E. Mortar for grouted riprap shall of 1:3 cement: sand mortar by volume. Water added shall be the least amount which will yield a mix of suitable consistency to ensure proper mortaring of riprap. Sand and cement shall conform with the relevant requirements of "Concrete and Concrete Mixes and Testing".
