DESCRIPTION A Tied Concrete Block Mat with Doubled Layered Underlayment. This work shall consist of furnishing and placing the system in accordance with this specification and conforming with the lines, grades, design, and dimensions shown on the plans. 2. MATERIALS Flexamat Standard is manufactured from individual concrete blocks tied together with high strength knitted polypropylene bi-axial geogrid. Each block is tapered, beveled and interlocked and includes connections that prevent lateral displacement of the blocks within the mats when they are lifted for placement. Tied Concrete Block Mat with Doubled Layered Underlayment shall be Flexamat Standard, manufactured by Motz Enterprises, Inc. 2.1. Blocks. Furnish blocks manufactured with concrete conforming to the cement requirements of ASTM C150 and to the aggregate requirements of ASTM C33. Blocks shall have a minimum weight of 3 Ib. per block and placed no further than 2 in. apart. Material weight per square foot shall not exceed 10 lbs. Blocks shall have a 2.25" profile, a flat -top pyramid shape, and a coarse finish without protrusions. Concrete shall have a minimum compressive strength requirement of Tablel and certified by a third party. Table 1 Concrete Compressive Strength Requirements Age 7 - Day Required Compressive Strength psi 5000 psi 14 — Day 6000 psi 28 - Day 6900 psi 2.2. Polypropylene Bi-Axial Geogrid. The interlocking geogrid shall be an open knitted fabric composed of high tenacity, multifilament polypropylene yarns knitted and coated in tension with an acrylic based coating which is designed to resist degradation in environments with exposure to water and low pH (,4 pH) and high pH (>9 pH). When combined with the revetment mat, this will yield a high tenacity, low elongating, and continuous filament polypropylene geogrid that is embedded within the base of the concrete blocks. Ensure the geogrid meets the requirements of Table 2. 1-4 Table 2 Polypropylene Bi-Axial Geogrid Property Unit Test Requirement Mass/Unit Area oz/yd2 ASTM D5261 6.5 oz/yd2 Aperture Size English units Measured 1.4x 1.4 inch Ultimate Wide Width Tensile Strength (MD x CMD) Ib/ft ASTM D6637 2,055 Ib/ft Elongation at Ultimate Tensile Strength (MD x CMD) % ASTM D6637 6% Wide Width Tensile Strength @ 2% (MD x CMD) Ib/ft ASTM D6637 822 Ib/ft Wide Width Tensile Strength @ 5% (MD x CMD) Ib/ft ASTM D6637 1,640 Ib/ft Tensile Modulus @2%(MDxCMD) Ib/ft ASTM D6637 41,100 Ib/ft Tensile Modulus @5%(MD xCMD) Ib/ft ASTM D6637 32,800 Ib/ft 2.3.

When seeding is shown on the plans, provide subgrade material that can sustain growth. Ensure the prepared subgrade provides a smooth, firm, and unyielding foundation for the mats. The subgrade shall be graded into a parabolic or trapezoidal shape to concentrate flow to middle of mat or mats. When vegetation is required, distribute seed on the prepared topsoil subgrade before installation of the concrete mats in accordance with the specifications. Install mats to the line and grade shown on the plans and per the manufacturer's guidelines. The manufacturer or authorized representative will provide technical assistance during preparation and installation of the concrete block mats as needed. Provide a minimum 18 in. deep concrete mat embedment toe trench at all edges exposed to concentrated flows. Recess exterior edges subject to sheet flow a minimum of 6 in.
