Specifications include, but are not limited to:. Sanding material paid for by weight cannot contain more than 4% moisture. Sanding material moisture content in excess of 4% will not be paid for. The amount of sanding material to be paid for, when moisture exceeds 4% shall be computed as follows:
maintenance">Pay Weight = (104 x Wet. Wt. Of Sand) Divided by (100 + % of moisture)
maintenance">Do not blend salt to sand when moisture content of sanding material exceeds 6%.
maintenance">Supply and add salt to the sand using a method acceptable to the Project Manager. The salt uniformly and distribute throughout the sand at the production site and at the specified rate. The use of a front-end loader to mix the salt with the sand is an unacceptable method.
Salt blended to the sand must be 100% passing the 3/4” sieve. Salt which is clearly non-compliant such as wet material or loads containing solid clumps/chunks will not be accepted. Finished product is to include the specified percentage of salt by weight.
Example: 2,500 tons of sand mixed with 15% salt by weight.
2,500/.85 = 2,941 total salt/sand mix
