The Role of Calcium Chloride in Secondary Road Maintenance
Introduction:
Secondary roads play a crucial role in transportation networks across the United States. However, maintaining these roads presents various challenges for road supervisors. This article will discuss the importance of maintaining secondary roads, the role of preventative maintenance programs, the need for a good gravel road, and the role of calcium chloride in road maintenance.
Importance of Maintaining Secondary Roads:
Secondary roads, often consisting of gravel surfaces, require regular maintenance to ensure safe and efficient transportation. These roads may not receive as much traffic as major highways but are crucial in connecting rural areas and providing access to various destinations. Neglected secondary roads can lead to rough rides, unsafe driving conditions, and increased maintenance costs.
Challenges Faced by Road Supervisors:
Road supervisors face numerous challenges in maintaining secondary roads. They must address issues such as rough surfaces, fugitive dust, lost aggregate, and higher costs. Maintaining gravel roads is a continuous task that requires significant effort and resources.
The Role of Preventative Maintenance Programs:
Implementing preventative maintenance programs is essential to prolonging the useful life of road machinery and saving money for both the highway department and taxpayers. These programs help stabilize secondary roads, reducing the need for frequent repairs and the associated costs.
The Need for a Good Gravel Road:
A good gravel road focuses on stabilizing the riding surface, rather than emphasizing the sub-base or base. Since these roads are primarily used by cars and light trucks, cohesion and compactness of the surface material are key factors. The binder soil, often clay-based, provides the necessary cohesive strength.
Choosing the Right Binder Material:
The ideal binder soil for a gravel road is gritty and passes through a quarter-inch sieve. It should retain sufficient moisture when dry and show minimal shrinkage. Too much sand can cause the road to fall apart, while excessive clay content makes the road prone to becoming slick in heavy rain and shrinking in dry weather.
The Importance of Surface Gravel Specifications:
A good surface gravel specification ensures the right balance of aggregate sizes and fines. The fines, or dust, act as the glue that holds the road together. The graded particles, when compacted, interlock to create a dense and smooth riding surface. The fines fill the voids between larger aggregate sizes, preventing them from shifting.
The Role of Fines in Road Stability:
Traffic compacts the fines into place, strengthening the road's structure. However, passing vehicles can dislodge the fines, especially if they turn into dust. To maintain road stability, it is crucial to keep the fines in place by preventing excessive dust generation.
The Role of Calcium Chloride in Road Maintenance:
Calcium chloride, when applied to secondary roads, helps control surface moisture and maintain optimal fines moisture content. It has hygroscopic and deliquescent properties, drawing moisture from the air. By keeping the fines moist and in place, calcium chloride enhances road cohesion, resulting in a smoother and dust-free surface.
Benefits of Using Calcium Chloride:
The use of calcium chloride in road maintenance programs offers several benefits. Firstly, it reduces nuisance and hazardous dust, improving driver visibility. Secondly, it creates a consolidated surface that resists washboarding and allows proper road drainage. Thirdly, it reduces aggregate loss, leading to tightly consolidated roads and significant cost savings.
The Six Reasons to Use Calcium Chloride in Road Maintenance Programs:
- It reduces dust, enhancing driver visibility and safety.
- It improves road quality by creating a consolidated and stable surface.
- It minimizes aggregate loss, resulting in substantial cost savings.
- It reduces the frequency of grading and lowers manpower and equipment costs.
- It increases road density and compaction, improving overall stability.
- It provides a compacted base for future paving, reducing preparation and paving costs.
Conclusion:
In conclusion, maintaining secondary roads is vital for safe and efficient transportation. A well-designed gravel road, supported by a comprehensive maintenance program, ensures stability and longevity. Calcium chloride plays a crucial role in maintaining secondary roads by controlling surface moisture and preserving the fines, ultimately reducing dust, complaints, and maintenance costs. By utilizing calcium chloride, road supervisors can provide smoother rides, save money, and keep the motoring public satisfied.
