- The use of calcium chloride for roads helps solve the problem of dust generation and surface drying during hot, sunny weather.
- It helps retain moisture in the road surface, reducing dust levels and improving driving comfort.
- Calcium chloride is widely used on gravel roads, unpaved roads, and industrial access roads.
- Calcium chloride dihydrate is available both as a solid product and in solution form.
Why is calcium chloride used for summer road maintenance?
Dust control and surface stabilization
During the summer months, dust becomes a major issue. Every passing vehicle causes fine particles to rise into the air and settle on buildings, machinery, facades, and parked vehicles. On roads running through industrial areas, farms, or residential zones, this negatively affects both everyday operations and the comfort of nearby residents.
A popular solution for summer gravel road maintenance is calcium chloride dihydrate. It helps reduce airborne dust and improves surface binding properties. As a result, roads remain more stable even under heavy vehicle traffic. This solution is widely used by road maintenance companies, infrastructure operators, industrial facilities, and agricultural businesses.
How does calcium chloride work on gravel roads?
The hygroscopic properties of calcium chloride
Calcium chloride dihydrate exhibits strong hygroscopic properties, meaning it absorbs moisture from the surrounding environment and helps retain it within the road surface. As a result, gravel, dirt roads, and unpaved surfaces dry out more slowly during hot weather conditions. This effectively reduces dust generation and limits the displacement of fine aggregate particles.
Maintaining an optimal moisture level in the road surface improves driving comfort and helps reduce the frequency of maintenance work. Calcium chloride dihydrate also supports surface durability by reducing the loosening of the top road layer, which may help slow down overall road wear.
Where is calcium chloride used for road maintenance?
- Municipal and local roads
- Industrial and service access roads
- Storage yards, gravel pits, and logistics areas
- Internal roads in agricultural facilities
- Parking areas, maneuvering yards, and loading zones
Which form of calcium chloride is used for road maintenance?
38% calcium chloride solution
A calcium chloride solution is commonly used for summer road maintenance. This form allows the product to be evenly applied across the surface and helps quickly reduce dust on unpaved and rural roads.
Granules and flakes – when are they used?
Calcium chloride dihydrate is also available in solid form. It is mainly used for on-site solution preparation or in smaller applications that require flexible dosing.
Granular calcium chloride and calcium chloride flakes are most commonly supplied in 25 kg bags. This makes the product easier to transport to locations with limited access for heavy equipment.
The importance of proper storage
Due to its hygroscopic properties, proper storage of calcium chloride is essential. The product should be protected from moisture and stored in tightly sealed packaging.
What should you pay attention to when purchasing calcium chloride for road maintenance?
When purchasing calcium chloride for road maintenance, it is important to consider not only the product form, but also supply reliability and consistent product quality. In practice, customers use both ready-to-use calcium chloride solutions and solid calcium chloride dihydrate.
Before placing an order, it is worth checking the availability of the required form, technical documentation, and the supplier’s ability to deliver larger volumes within short lead times. For larger projects, the ability to align deliveries with the maintenance schedule is also an important factor.

FAQ: Calcium chloride for summer road maintenance (frequently asked questions)
How long does the dust control effect last after applying calcium chloride?
The performance of calcium chloride for road maintenance depends on several factors, including weather conditions, especially prolonged dry periods, traffic intensity, and the type of road surface. In practice, the dust control effect can last from several weeks up to a few months.
Is calcium chloride suitable for roads with heavy vehicle traffic?
Yes, calcium chloride for road maintenance is also used on roads exposed to intensive heavy truck traffic and industrial machinery. However, in areas with very high traffic intensity, more frequent application of the product may be required.
Is calcium chloride used only during summer?
No. Calcium chloride for road maintenance is used for both summer and winter road maintenance applications. During summer, it helps reduce dust and surface drying, while in winter it is commonly used to maintain road and pavement passability in low temperatures.
What packaging options are available for calcium chloride dihydrate?
At Centro-chem, solid calcium chloride dihydrate is available in 25 kg bags. Calcium Chloride Solution 38% – chemical raw material – fast delivery is typically supplied in 1000 L IBC containers, 200 L drums, or smaller 5–30 L canisters.
