About this file
This is a Material Specifications document for the New York State Department of Transportation (NYSDOT) outlining requirements for sodium chloride rock salt to be used for snow and ice control across Regions 1, 3, 5, 7, and 9. The salt must meet ASTM D632 Type 1, Grade 1 standards with a minimum sodium chloride content of 95 percent and specific particle size distribution requirements across multiple sieve sizes. Strategic reserves must be physically available on or before January 1, 2027, and dedicated exclusively for NYSDOT use, with all deliveries to be completed by the end of March 2027. The specification establishes detailed testing and sampling procedures, with NYSDOT reserving the right to collect samples from contractor stockpiles or shipments at points of destination.
The specification establishes strict quality control measures with associated price deductions for non-compliance. Moisture content upon delivery shall not exceed 1.5 percent, with price reductions applied using a specified formula if moisture content exceeds 2.0 percent. Gradation deviations from specified tolerances result in proportional price deductions calculated through a defined formula. Salt must be treated with an anticaking inhibitor in the range of 0.1 to 0.2 pounds per ton, with vendors required to provide detailed information about the inhibitor treatment, solubility, photodecomposition, and potential ecological impacts. Lumpy or contaminated salt may result in rejection of entire deliveries or a 10 percent price deduction if operationally accepted. The contract is subject to cancellation if the contractor consistently delivers salt exceeding 2 percent moisture content or fails to meet gradation requirements. All calculations must follow ASTM Recommended Practice E-29 rounding standards.

Attachment 2
Material Specifications
Material Specifications – Road Salt (Rock)
It is the intent of this specification to describe sodium chloride (ASTM D632 Type 1, Grade
1 or the latest revision thereof) crushed Rock Salt to be used for snow and ice control.
Chemical Composition
Shall be not less than 95% sodium chloride. Percent of sodium chloride shall be determined in accordance with ASTM D632 or the latest revision thereof.
Size Grading – Rock Salt
The salt, when tested in accordance with ASTM D632 (*) or the latest revision thereof, shall conform to the following requirements for particle size distribution:
Sieve Size Percent Passing (**)
1/2” - (12.5 MM) 100
3/8” - (9.5 MM) 95 – 100
No. 4 - (4.75 MM) 20 – 90 No. 8 - (2.36 MM) 10 – 60 No. 30 - (600 MICRONS) 0 – 15
* A drying temperature of 110°C + 5°C may be used.
**Tolerance of 5 percentage points on the maximum value of the range for each sieve except 1/2" (12.5 mm) and 3/8" (9.5 mm) sizes, on which no tolerance will be allowed.
Moisture Content
Moisture content upon delivery shall not exceed 1-1/2% (*) when determined as follows:
% Moisture = (W1 - W2) x 100 / (W1)
W1 = initial weight of sample
W2 = weight of sample after drying to a constant weight at 110°+5°C.
* Procedure shall be in accordance with ANSI/AWWA B200-03, Moisture
Determination or the latest revision thereof. A tolerance of 0.5% will be allowed before a deduction is assessed.
Inhibitor Treatment
Salt shall be treated with an anticaking conditioner. The quantity of inhibitor used shall be in the range of 0.1 to 0.2 lbs/ton. Potential vendors shall supply with their bid a description of the inhibitor treatment used, quantity of inhibitor used per ton of salt, method of determining the presence of the treatment and information relative to the solubility and photodecomposition of the treating agent. Potential harm to the ecology caused by inhibitor treatment may be cause for rejection of a bid.
Salt delivered in a lumpy condition which requires reprocessing in order to make it usable shall be cause for rejection of the entire delivery, with a replacement delivery to be made at no additional charge to NYSDOT.
If, because of emergency conditions, it is necessary to accept and reprocess the salt for use, all costs will be charged to the contractor.
Sampling
Sampling shall be done in accordance with current ASTM D632 or the latest revision thereof. NYSDOT reserves the right to take samples from the contractor’s stockpile or from shipments at the point of destination.
The right is also reserved to consider truckloads of salt delivered by the contractor to any one delivery location on a single day to be a single delivery. Price deductions imposed because of deviation from specifications may be imposed on the total day’s delivery.
Price Deductions
No price deduction is to be assessed unless the proper analysis and test procedures are followed.
If the contractor consistently delivers salt found to be above 2% moisture content or consistently not conforming to the gradation requirements, the contract shall be subject to cancellation.
Moisture
If, after delivery the moisture content is found to be above 2.0%, a price deduction for moisture content will be made from the delivered bid price based on the following formula:
Reduced price per ton = delivered contract price per ton x (1.02 - 2X) where X = moisture content of the sample (expressed as the decimal equivalent of the percentage of the original sample weight to the nearest
1%).
Gradation (Particle Size Distribution)
If, after delivery, the gradation of the Salt is found to be out of tolerance a deduction from the price shall be made based on the following formula:
Reduced price per ton = delivered contract price x (1.00 - X) where X = the decimal equivalent of the total % out of gradation less the tolerance. The % out of tolerance for each sieve shall be to the nearest 1%.
The total of the individual sieve tolerance deviations shall be used as X.
Contamination
If the end user accepts contaminated salt as defined in Section “Inhibitor
Treatment” for operational reasons, a 10% price deduction may be placed on the contractor by the end user after consultation with the contractor.
NYSDOT WILL HAVE FINAL APPROVAL AS TO DELIVERY DEDUCTION
APPLIED IN REGARD TO CONTAMINATION.
Calculations
Calculations performed relative to this specification shall be made using the rounding off method of “ASTM Recommended Practice E-29 for Designating
Significant Places in Specified Limiting Values”.
