Specifications include, but are not limited to: A Class I Material Transfer Vehicle (MTV) will have load restrictions during placement of asphaltic concrete in the station range of 225+59 to 261+00. The Class I MTV shall be equipped with a “warning light” system having a daytime visibility that is satisfactory to the Engineer and which activates at a pre-determined limiting value of not more than 16 tons, and remains activated until the quantity of material in the hopper becomes less than that pre-determined limiting value. [Example: Maximum hopper capacity is 25 tons and a “warning light” activates (e.g., comes on, changes color, starts blinking, etc.) when the hopper is 60% full. The “pre-determined limiting value” is 15 tons (0.6 x 25 ton)] A Class I MTV shall not be used to place asphaltic concrete in areas of load restrictions if the MTV’s hopper is loaded with 16 tons or more of material. When the warning light indicates that the MTV is loaded to the pre-determined limiting value, the Contractor shall immediately take steps to reduce the rate of inflow of asphaltic concrete into the MTV hopper. The MTV shall not be used to place asphaltic concrete after it has placed a nominal 50 tons (e.g., 2-truckloads) of asphaltic concrete while the warning light is activated. Any asphaltic concrete in a front of the MTV shall be relocated until the MTV reaches an approximate 10-ton loading level or less. Any damage caused while the MTV was overloaded shall be repaired to the satisfaction of Engineer at no cost to the Department of Transportation.
