726.01 DESCRIPTION. Furnish and place aggregate bedding material
on geotextile fabric for drainage structures .
726.02 MATERIALS. Materials shall comply with the following
subsections: Plastic Soil Blanket 203.10 Bedding Material 1003.10 Geotextile Fabric 1019.01
726.03 PLACEMENT OF BEDDING . Place geotextile fabric in
accordance with plan details prior to placing bedding material. Properly proportion and mix bedding materials prior to placement in the foundation. Take care to prevent damage to geotextile fabric during placement of bedding material. Place, shape, and uniformly compact bedding material to the satisfaction of the engineer. Overlap or sew adjacent rolls of geotextile fabric. When rolls are overlapped , overlap a minimum of 18 inches , including the ends of the rolls. Assure that the top layer of the fabric is parallel with adjacent rolls and in the direction of bedding materials placement. When rolls are sewn, join adjacent rolls by sewing with thread made of polyester or a material with equivalent strength and durability. When field sewing, employ the J-seam or “Butterfly” seam with the two pieces of geotextile fabric mated together and turned in order to sew through four layers of fabric. Sew with 2 rows of Type 401, two-threaded locking chain stitch. Submit factory seams other than specified to the Materials and Testing Section for approval. When the ground is covered with water or supersaturated soil, sew the fabric. Remove damaged fabric and replace with new fabric or cover with a second layer of fabric extending two feet in each direction from the damaged area. Use material excavated below the established grade of the structure or dispose of it in accordance with Section 203 . Place a plastic soil blanket in accordance with 203.10 at structure ends when bedding material is exposed.
