Type A Water -reducing admixtures Type B Retarding admixtures Type C Accelerating admixtures Type D Water -reducing and retarding admixtures Type E Water -reducing and accelerating admixtures Type F Water -reducing, high range admixtures Type G Water -reducing, high range, and retarding admixtures
c.Acceptance of Material for Use . The Department has established a list of Chemical Admixtures For Use In Portland Cement Concrete. These products can be found on List II -1 of the Department’s "Materials, S ources, and Devices With Special Acceptance Requirements" Manual. Refer to Subarticle 106.01(f) and ALDOT -355 concerning this list.
810.01 Geotextile Filters.
Geotextile filters shall m eet the appropriate chemical and physical requirements of AASHTO M 288 for the application for which the material is to be used. The Department has established a list of acceptable Geotextiles. Only the materials on this list shall be furnished for use. Th is list, List II -3, is given in the "Materials, Sources, and Devices With Special Acceptance Requirements" Manual. Information concerning this list is given in Subarticle 106.01(f) and ALDOT -355. Geotextile rolls shall be furnished with a suitable wrappin g for protection against moisture and extended ultraviolet exposure prior to placement. Each roll shall be labeled or tagged to provide product identification sufficient for inventory and quality control purposes. Rolls shall be stored in a manner which protects them from the elements. If stored outdoors, they shall be elevated and protected with a waterproof cover. The geotextile shall be formed in widths of not less than 6 feet {2 m}. Sheets of geotextile may be sewn together with thread of a material meeting the chemical requirements given for the plastic yarn to form filter widths as required. The sheets of geotextile shall be sewn together at the point of manufacture or another approved location. SECTION 811 POLYMER ADDITIVES FOR ASPHALT MATERIALS
811.01 General.
Any polymer not specifically addressed in this Section shall not be used. Variations in composition of polymers listed in this Section will also be considered, if requested in writing to the M aterials and Tests Engineer. The use of any polymer shall require the submittal of a written certification to the Materials and Tests Engineer from the manufacturer showing test results for physical properties of the material including, as a minimum, polym er types, polymer percentages, percentage of any cross linking agent and specific gravity. The manufacturer shall also submit a procedure for incorporating the polymer into the asphalt material for actual production and laboratory blending, which would inc lude blending procedures, desired temperatures, duration of blending, etc. A sample of the bituminous material along with an infrared trace using ALDOT 408 procedure or AASHTO T 302 for emulsions showing the styrene and butadiene peaks and percentage of po lymer shall also be submitted by the refinery to the Department for laboratory evaluation prior to use. This submittal shall be made annually or upon request by the Department or if the manufacturer changes polymer sources. Field blends of emulsions shall not require an FTIR trace.
