- STONE FOR RIPRAP, DITCH LINING AND OTHER MISCELLANEOUS USES STONE FOR RIPRAP, DITCH LINING AND OTHER MISCELLANEOUS USES

1114.1DESCRIPTION

This specification covers stone for the following uses: • Riprap • Aggregate Ditch Lining (D50) • Filter Course • Flumes, Flume Drains and Slope Drains • Tree Wells or Cribs • Shot Rock • Granular Drainage Blanket • Sediment Basin Risers Where referred to, quarried stone is defined as limestone, dolomite, calcite cemented sandstone, rhyolite, quartzite, basalt and granite, removed from naturally occurring formation by standard extraction and sizing methods. Recycled PCCP may be used for Riprap, Ditch Lining, and Shot Rock, provided the respective Soundness and Wear requirements are met.

1114.2REQUIREMENTS

Documents.

• Soundness, minimum (KTMR-21) ................................................................................ 0.85 • Wear, maximum (AASHTO T 96) ............................................................................... 45% • Inspection of the quarry ledge, stock piles, and available sites where comparable stone from the same bed(s) is in service to verify the Product Control requirements have been met.

• Provide stone for riprap that is free of soil, shale or shale-like material and cracks, seams or other defects that will decrease the durability 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. - STONE FOR RIPRAP, DITCH LINING AND OTHER MISCELLANEOUS USES TABLE 1114-1: STONE FOR RIPRAP* Class Percent Heavier Than 8 ton 4 ton 2 ton 1 ton ½ ton ¼ ton 250 lbs 200 lbs 100 lbs 75 lbs 5 lbs Heavy Series 8 Ton 50+ 95+ 4 Ton 0 50+ 95+ 2 Ton 0 50+ 95+ 1 Ton 0 50+ 95+ ½ Ton 0 50+ 95+ ¼ Ton 0 50+ 90+ Light Series Facing 0 50+ 90+ Light 24” 0 50+ 90+ Light 18” 0 50+ 90+ *Percent of total sample weight composed of pieces heavier than the indicated weight

• Provide stone for ditch lining that is free of soil, chert, 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.
