Vertical 04 · Road & De-IcingAASHTO M143

Highway-grade de-icing salt. Pre-positioned for the storm.

Bulk sodium chloride meeting AASHTO M143 specification for DOT, county, and municipal winter maintenance programs. Seasonal pre-positioning converts spot exposure into contracted tonnage — with end-dump and live-floor dispatch into your stockpile yard.

01 — Specifications

The technical envelope DOT and public works specify against.

Standard
AASHTO M143American Association of State Highway and Transportation Officials standard for highway sodium chloride. Minimum NaCl content, gradation, and moisture limits.
NaCl Content
95%+ sodium chlorideDocumented per lot. Highway de-icing tolerates broader purity than municipal water grades; consistency and gradation drive performance.
Particle Gradation
Highway-grade distributionSized for DOT spreader equipment to avoid bridging in hoppers and to optimize residence time on roadway surfaces.
Anti-Caking
Available on requestFor long-term outdoor stockpiling and humid southern-corridor staging, anti-caking treatment maintains flow through spreader hoppers.
Discharge Methods
End-dump · Live-floor · FlatbedEnd-dump and live-floor are standard for stockpile yards. Flatbed for smaller commercial and parking-lot accounts.
Seasonal Logistics
Q3 staging · Q4–Q1 dispatchTonnage commitments pre-positioned in regional stockpiles ahead of winter maintenance season. Eliminates spot-market exposure during peak-storm demand.
02 — Applications

Where this product runs across winter maintenance.

State DOT & highway authorities

Contracted tonnage for interstate and state-route maintenance. Seasonal pre-positioning aligned to historical storm-day frequency and route-mile responsibility.

County & municipal public works

Mid-volume bulk delivery into county yards and municipal storage. End-dump discharge with seasonal flexibility for above-historical winter events.

Commercial & pre-treatment brine

Sodium chloride feedstock for on-site brine generation supporting anti-icing and pre-storm liquid application. Bulk and supersack packaging for parking-lot service contractors.

03 — Procurement FAQ

Answers DOT and public works ask first.

What is AASHTO M143 specification for highway de-icing salt?

The AASHTO standard for sodium chloride used in highway maintenance — minimum NaCl content, particle gradation, and moisture limits suitable for spreader equipment and brine-formation performance on roadways.

How does seasonal pre-positioning work for DOT contracts?

Tonnage commitments are positioned in regional stockpiles ahead of the winter season — typically Q3 staging for Q4–Q1 dispatch. This converts spot-market price exposure into contracted unit costs and guarantees availability during peak-storm logistics demand.

Can salt be supplied alongside calcium or magnesium chloride?

Yes. For lower-temperature applications and pre-treatment brine programs, sodium chloride can be supplied with calcium chloride or magnesium chloride for on-site blending. Brine-system feedstock for direct liquid application is also available.

What unloading methods does road salt typically use?

End-dump and live-floor trailers are standard for roadway salt — direct into DOT and municipal stockpile yards. Flatbed delivery is available for smaller commercial and parking-lot accounts.
