Recycled PCCP may be used for Riprap, Ditch Lining, and Shot Rock, provided the respective Soundness and Wear requirements are met. 1114.2 REQUIREMENTS
a.Stone for Riprap .
1.Composition. Provide quarried stone for riprap that meets the installation class specified in the Contract Documents. (2) Quality. Soundness, minimum (KTMR-21) ................................................................................ 0.85 Wear, maximum (AASHTO T 96) ............................................................................... 45% Inspection of the quarry ledge, stock piles, and av ailable sites where comparable stone from the same bed(s) is in service to verify the Product Control requirements have been met.
3.Product Control. Provide stone for riprap that is free of soil, shale or shale-like material and cracks, seams or other defects that will decrease the durab ility of the material after placement. Provide riprap from sources that have been inspected and approved by the KDOT Geologist. A riprap source may be rejected if more than 15% of the product from the source deteriorates within 5 years of exposure, either in service or in a natural weathering test plot (such as a boulder pile at the quarry). Deterioration is defined as any one piece losi ng more than 25% of its original volume either due to damage during handling and placement or due to cracking or splitting as a result of weak seams in the rock. Determination is made by visual inspection. Size. The class requirements are given in TABLE 1114-1 . 1114 - STONE FOR RIPRAP, DITCH LINING AND OTHER MISCELLANEOUS USES

3.Production Control. Provide stone for ditch lining that is free of soil, ch ert, shale or shale-like material and cracks, seams, or other defects that will decrease the durability of the material after placement. No more than 10% of individual rocks shall have their least dimension less than 1/3 of their greatest dimension. Provide ditch lining from sources that have been inspected and approved by the KDOT Geologist. A ditch lining source may be rejected if more than 15% of the product from the source deteriorates within 5 years of exposure, either in service or in a natural weathering test plot (such as a boulder pile at the quarry). Deterioration is defined as any one piece losing more than 25% of its original volume either due to damage during handling and placement or due to cracking or splitting as a result of weak seams in the rock. Determination is made by visual inspection. Size. Provide stone for ditch lining that complies with TABLE 1114-2. TABLE 1114-2: STONE FOR AGGREGATE DITCH LINING (D 50) Size D50 Max.
