c.Fly Ash for Modification. Meet or exceed a compressive strength of 100 psi at 7 days.
d.Storage and Handling. Store and handle fly ash in closed waterpr oof containers before distribution on the roadway or fill. Other methods of storag e and handling are subject to the approval of the Engineer. Partially caked or set fly ash is unacceptable for use. 2005.3 TEST METHODS Sample the fly ash using KT-29. Test the chemical composition of fly ash in accordance with ASTM C 311. Test physical properties of fly ash by ASTM D 5239, paragraph 6.4. 2005.4 PREQUALIFICATION New sources, sources that have not been used on a KDOT project within the last 12 months, and sources which have allowed the required monthly reporting of quality control test results to lapse, must be prequalified.

2.Quality and Size. Provide plants that comply with all applicable portions of ANSI Z60.1. Only plants free of noxious weeds, insect infesta tions, mechanical injury, di seases, or defects are acceptable for use under this specification. Plant growth is to be vigo rous, symmetrical and typical for the species. Provide the minimum acceptable size specified in the Contract Documents, meas ured before pruning and with branches in normal position. Larger plants may be substituted, at no change in the Contract unit price, if approved by the Engineer.
3.Container Plants. Container grown nursery plants may be substituted for balled and burlapped plants if approved by the Engineer. (4) Inspection of Plants. Plants must comply with any permits, certifications or inspections required by State, Federal or other authorities. Inspection by the Engi neer of all plants may be done at any time before final planting. Immediately remove reject ed plants from the project site. Identify the plant’s genus, species, cultivar and common na me with a tag attached to each plant or attached randomly in groups of smaller plants. Plants held in storage will be rejected if they show si gns of shriveled and dry tops or roots, or if the plant has new growth that developed while in storage. Move deciduous plants from the nursery field before leaf buds have opened. Deciduous plants moved after leaf buds have opened will be rejected, unless written approval is provided by the Engineer.
b.Balled and Burlapped Plants (B & B). Balls must be firm, natural and completely wrapped with jute, flax or hemp burlap. Do not wrap using plastic or polyethylene fabric wrapping. Secure the burlap with rope, twine or wire to hold the ball in a firm, rigid condition. Balls that are crushed, deformed or broken will be rejected. Only nursery stock that has been harvested during the current planting season is acceptable. The Engineer may accept plants with root balls smaller than specified if the plants were grown in “root control, in-ground containers.” Remove the fabric bag for root controlled plants and secure the earth ball with burlap before planting.
c.Container Plants. Provide only plants grown in the container for a minimum of 4 months. When the plant is removed from the container for planting, the soil mixture must remain intact with the r oot system reaching the sides of the container. Do not use plants with a heavy, twisted root mass circling the bottom of the container.
d.Bare Root Plants. Provide nursery grown plants with well branched root systems which are characteristic of the species presented. Saturate the root system with an anti-transpiran t gel or treat with acrylates and protect from moisture loss with a suitable covering.
e.Transplanting Established Materials. All established trees, shrubs, and other plants on a project that are to be transplanted are indicated in the Contract Docu ments. The method of moving will be shown, such as B &
B.Use the ball and burlap method when transplanting out of season or when the plants are leafed out. B & B is always used when transp lanting evergreen plants. 2102 - PLANTS
