Material shall be tested for ice melting (SHRP H205.1), ice penetration (SHRP H 205.3) and ice undercutting

(SHRP H205.5).

A. SOLID SNOW AND ICE CONTROL MATERIALS WITHOUT CORROSION INHIBITORS

Scope: Solid snow and ice control materials without corrosion inhibitors shall conform to the following additional requirements. Sampling examining and testing shall be done according to ASTM D345 and E449 unless stated otherwise.

1. SODIUM CHLORIDE SOLID

a. Sodium chloride shall conform to the requirements of AASHTO M143, Type I, Grade I.

b. Moisture content shall not exceed 2.0 percent.

c. When sampled at the destination, 5 percent tolerances on the 3/8 inch (9.5mm) sieve will be permitted.

All plus 3/8 inch material shall have 100 percent passing the ½ inch (12.5mm) sieve.

d. The sodium chloride will be tested according to Virginia Test Method VTM-28 and shall not be less than

95.0 percent sodium chloride.

e. Shipments from Approved Stockpiles: Whenever it is feasible, samples will be taken from protected stockpiles at the maximum rate of one composite sample (made from 3 increment samples) per 10,000 tons.

Samples will be taken according to AASHTO M143.

f. The manufacturer shall notify VDOT Materials Division (804-328-3123), before stockpiles are covered so proper sampling can be done. Whenever a supplier adds more salt to an existing stockpile, new samples will be taken to represent this modified stockpile. When inspection at the stockpile is not practical, samples of shipment of material will be taken at the final destination at the rate of approximately one composite (made from 3 increment samples) sample per 5,000 tons.

g. Shipping or delivery tickets shall indicate that the sodium chloride has been shipped from an approved source. This certification shall be stamped on the shipping or delivery tickets and shall be signed by an authorized representative of the company. Salt shall be delivered in a clean truck bed and shall be protected during transit with a waterproof cover.

h. Anticaking agent: The quantity of the agent used shall be in the range of 0.1 to 0.2 pounds per ton.

Contractor shall ensure a consistent through mix of the anti-caking agent throughout the truckload.

STOCKPILE REJECTION:

When the stockpile is rejected, no shipments will be accepted from it. Resampling will be allowed for those stockpiles according to AASHTO M143.

Stockpiles will be rejected when more than one third of the samples fail any of these specifications.

a. Moisture content in excess of 3.0 percent.

b. Sodium chloride content less than 92.0 percent.

c. Stockpile deviates more than 10 percent from these specifications.

d. Stockpiles contain ¾ inch or ½ inch material.

PRICE PENALTIES:

All shipments will be subject to visual inspection at final destination at the time of unloading. Sodium chloride shall arrive at the final destination in a free-flowing and usable condition. Any shipment deemed to be unusable because of excessive water, oversized material, excessive caking or reduced sodium chloride content may be rejected at the option of the Engineer or VDOT representative. A sample may be taken for testing by VDOT.

The producer shall, at its own expense, send an inspector to the site, remove and replace the rejected material, or send equipment to resolve the concern, such as sieve to remove over-sized material on-site. VDOT representatives shall be consulted for their preference.

3. Procedure for determining moisture and gradation of sodium chloride sample

3.1 The sample is split to approximately 150 gm ( 50) and placed in a tared 8 oz. metal can and weighed to the nearest

0.10 gram.

3.2 The metal can with sample is placed in an oven at 110 ºC, dried overnight, cooled in desiccator and reweighed.

The loss in weight is the amount of water present. The percent water is calculated as:

% Water = A - B X 100 A

A = weight of wet salt B = weight of dried salt

3.3 The dried sample is then sieved and the gradation is determined by calculating percent sample retained on each sieve to total sample sieved. The gradation should conform to AASHTO M143 Type I.

3.4 The sample is recombined, split down to about 5 gm, ground with a mortar and pestle and placed in a 3 oz.

metal can.

4. Procedure for determining chloride content of sodium chloride sample.

4.1 Weigh 2 gm of ground sample to the nearest 0.1 mg and transfer to a 1000 ml volumetric flask. Fill to the mark with deionized water and mix well.

4.2 Pipet a 10 ml aliquot into a 120 ml plastic memo beaker and add enough deionized water to cover the electrode.

4.3 Standardize the 0.1 N AgNO3 titrant with the 0.1 N NaCl using the Method 900 on the MemoTitrator.

4.4 Titrate the sample using Method 91102. The instrument will ask for weight of the sample and the identification number. It will titrate the sample automatically and record the results as % NaCl in a dried sample. Results are reported as % of NaCl in sample as received from the field.
