- 800 - SECTION 1013 -- BITUMINOUS LIQUID COMPOUNDS FOR CURING CONCRETE
1013.01 Description
1.The compound shall consist of an asphaltic base and shall be of a consistency suitable for spraying at tem peratures existing at the time of construction operations. It shall be applied to form a continuous, uniform film. It shall be free of precipitated matter caused by conditions of storage or temperature. The compound shall be relatively nontoxic.
1013.02 Material Characteristics
1.When tested in accordance with AASHTO T 155, the loss of water shall not be more than 0.11 lb/ft² (0.55 kg/m2) of surface area at 3 days, unless otherwise specified by the Engineer.
1013.03 Acceptance Requirements
1.The base material shall confor m to Sections 1030, 1031 and 1032. - 801 - SECTION 1014 -- JOINT AND CRACK SEALING FILLER
1014.01 Description
1.Joint sealing filler shall be either a cold applied silicone product or an asphalt product (hot pour) conforming to the requirements of the contract. The type of joint filler to be used shall be as specified in the contract. If not specified, any of the joint sealing fillers in this Section may be used.
2.Crack sealing filler shall be a hot pour sealer conforming to the requirements of the contract.
1014.02 Material Characteristics
1.NE – 3405 and NE-3405LM (hot pour)
a.NE-3405 joint and crack sealer shall conform to the requirements of ASTM D 6690, Type II. The material shall conform to the requirements of Table 1 with the following exceptions:
1.The test of Bond, non-immersed, ASTM D5329, 3 specimens through 3 cycles shall be run at 0oF (-18oC), 100% extension.
b.NE-3405LM (Low Modulus) joint and crack sealer shall conform to the requirements of ASTM D6690, Type IV. The material shall conform to the requirements of Table 1.
c.The test of Bond, non-im mersed, ASTM D5329, will be tested on concrete blocks which are construc ted by the Depart ment’s Concrete Laboratory. The materials used are a common design in Nebraska concrete paving specifications. The design is a 47 B concrete mixture as specified in Section 1002 of the Depart ment’s Standard Specif ications. The design is amended to not include flyash, but a ll other specifications for Portland Cement Concrete apply.
d.Sample conditioning, preparation and heating shall be in accordance with ASTM D5167 with the following exceptions:
1.The following sentence of 8. 1.2, “Also, if present, remove container liner by cutting it away”, is void and superseded by the following: “Also, if present, as much of the polyethylene bag as possible, shall be removed by cutting it away. Wholly-meltable type container in adhered contact with the sample section is left in place. For wholly-meltable type containers that do not adhere to the se alant material, a pro-rated amount of the meltable type container shall be added to the sample.”
2.The last sentence of secti on 8.1.2 “Solid Materials” is void and superseded by the follow ing: “The entire vertical section which has been cut, shall be placed into the pot for melting.”
3.The Section of 8.2.2.1 “Solid Materials” is void. (4) The Section of 8.2.3 is void and superseded by the following: “After the solid segment is added to the melter, the material shall be allowed to melt to a uniform viscous state suitable for the installation of the stirrer or paddle. The sample shall then be stirred for one full hour. The oil bath temperature shall be regulated to bring the material to the maximum heating temperature within the one full hour of stirring.”
5.The Section of 8.2.4.1 is void and superseded by the following: “During the one full hour of stirring, check the temperature of the material at maximum 15 minute intervals using a Type K thermocouple with
