299 certain areas, ensure that the method of sprinkling will not form mud or pools of freestanding water. Correct soft or yielding subbase areas prior to placement of RCC as specified in Section 6.1 above.
514.9.2-Adverse Weather Conditions: 514.9.2.1-Cold Weather Precautions: Employ cold weather precautions as detailed in Section 601.9.1 of the Specifications. Stop placement operations when the air temperature falls below 40°F and is declining. Start operations only if the air temperature rises above 35°F and is elevating. If the air temperature is expected to fall below 40°F at some time during construction, and if the Contractor plans to place RCC during that time, the Contractor shall advise the Division of his plans for cold weather curing and protecting the RCC. The Division may, at any time, require the Contractor to provide additional protection to cause the provisions of this specification to be met.
514.9.2.2-Hot Weather Precautions : Employ hot weather precautions as detailed in take special precautions to minimize moisture loss due to evaporation. Cooling of aggregate stockpiles by shading or the use of a fine mist may be required. Protective covers may be req uired on dump trucks. Keep the surface of the newly placed RCC pavement continuously moist. The Engineer may decrease the allowable time, specified in Section 514. 10.1, between mixing and the completion of compaction when the ambient temperature exceeds 90°F or during windy conditions. In no event shall RCC be placed when its temperature at any time after the completion of mixing exceeds 90°F.
514.9.2.3-Rain Limitations: Conduct no placement of RCC pavement during rain conditions sufficient to be detrimental to the finished product. Placement may continue during light rain or mists provided the surface of the RCC pavement is not eroded or damaged in any way. Use dump truck covers during these periods. The WVDOH may terminate paving at any time w hen, in the WVDOH judgment, the rain is detrimental to the finished product.
514.9.3-Paver Requirements : Place all RCC with an approved paver as specified in Section 514.5.3, and also meeting the requirements of this Section.
514.9.3.1-Filling the Pa ver: Do not allow the quantity of RCC material in the paver to approach empty between loads. Maintain the material above the auger at all times during paving.
514.9.3.2-Stopping the Paver : Ensure that the paver proceeds in a steady, continuous operation with minimal starts and stops, except to begin a new lane. Maximum paver speed during laydown is ten (10) feet per minute. Higher paver speeds may be allowed at the discretion of the WVD OH if the higher speeds may be obtained without distress to the final product or cause additional starts and stops.
