Construction on roads throughout the District is required for both planned road improvement projects and emergency repairs to our infrastructure. The District is committed to keeping our roads open to the extent possible to avoid traffic impacts and, when a full road closure is required, to provide as much advance notice as we can. When a road closure is required, we make best efforts to re-open the road as quickly and as safely as possible.

Pulverization |
Road resurfacing is a process of renewing the top layer of a road to improve its condition, appearance, and safety. Pulverization is a crucial step in this process that involves the complete removal of the existing asphalt or concrete pavement. During pulverization, a specialized machine called a pulverizer is used to crush the existing pavement into small pieces. The pulverizer grinds the pavement to a depth of several inches, breaking it down into small particles that are then mixed with the underlying soil. The resulting mixture is then compacted to form a stable base for the new road surface. Pulverization is an effective way of recycling old road materials and reducing waste. By pulverizing the old pavement, the material is reused as a base for the new road surface, eliminating the need to transport and dispose of the old pavement in a landfill. |
Microsurfacing |
Similar to Slurry Seal but for use on higher volume (or hot mixed asphalt) roadways, microsurfacing is a type of road maintenance activity that involves applying a thin layer of asphalt-based material to the surface of a road. This material is a mixture of asphalt, water, aggregate (such as small stones), and various other additives. The mixture is applied to the road surface using a specialized machine that sprays it in a uniform layer. The material is then smoothed out and left to dry and cure. Once the material has hardened, it forms a new wearing surface on the road that is resistant to water, UV rays, and other environmental factors that can cause damage to the road. Microsurfacing is often used as a preventative maintenance measure for roads that are beginning to show signs of wear and tear. It can help to extend the life of the road by several years and prevent the need for more expensive repairs in the future. It is also a relatively quick and cost-effective method of road maintenance compared to other options. Overall, microsurfacing is an important tool in maintaining the safety and functionality of our roadways, and it can help to ensure that drivers and other road users can travel safely and smoothly. |
Slurry Seal |
Similar to Microsurfacing but for use on lower volume high float roadways, slurry seal is a pavement treatment method that involves the application of a thin layer of asphalt emulsion mixed with fine aggregate and mineral filler to the surface of the pavement. The mixture is applied to the pavement surface using specialized equipment that spreads it evenly across the roadway. The slurry seal mixture is designed to seal the surface of the pavement and provide a new, smooth wearing course that can extend the life of the pavement. It can be used on a variety of pavement surfaces, including both asphalt and concrete, and is typically applied to roads that have minor surface defects or that require preventive maintenance. One of the key benefits of slurry seal is its ability to fill in minor cracks and imperfections in the pavement surface, preventing water from penetrating the pavement and causing further damage. It is also highly effective at protecting the surface of the pavement from the damaging effects of sunlight, oxidation, and other environmental factors. The slurry seal application process typically involves several steps, including surface preparation, the application of the slurry mixture, and curing. Surface preparation involves cleaning the pavement surface and repairing any major defects, such as potholes or cracks. The slurry mixture is then applied to the pavement surface using specialized equipment, and allowed to cure before traffic is allowed back on the roadway. |
High Float Surface Emulsion |
Used on lower volume roads, high float surface emulsion (often called tar and chip) is a pavement treatment method that involves the application of a specialized asphalt emulsion mixture to the surface of the pavement. The mixture contains a high concentration of polymers and other additives that make it more resistant to wear and damage. This process is used in tandem with the pulverization process described above. The high float surface emulsion mixture is typically applied to the pavement surface using specialized equipment that spreads it evenly across the roadway. It is designed to provide a new, durable wearing course that can extend the life of the pavement and protect it from the damaging effects of traffic, weather, and other environmental factors. One of the key benefits of high float surface emulsion is its ability to create a durable, long-lasting surface that can withstand heavy traffic and other forms of wear and tear. It is also highly effective at sealing the surface of the pavement, protecting it from water damage, oxidation, and other environmental factors. The high float surface emulsion application process typically involves several steps, including surface preparation, the application of the emulsion mixture, and curing. Surface preparation involves cleaning the pavement surface and repairing any major defects followed by the addition of specialized gravel to receive the emulsion treatment. The emulsion mixture is then applied to the gravel surface using specialized equipment, and allowed to cure before traffic is allowed back on the roadway. |
Hot Mix Asphalt Paving |
For use on higher volume roadways, hot mix asphalt paving is a process of laying down a mixture of hot asphalt binder and aggregate (such as gravel, sand, and crushed stone) on a prepared (pulverized and fine graded) surface. This mixture is typically heated to a temperature of around 150-175 degrees Celsius to make it easier to work with and ensure proper compaction. This process is used in tandem with the pulverization process described above. The process begins with the preparation of the surface, which includes cleaning and removing any debris or obstacles that could interfere with the paving process. Once the surface is pulverized and prepared, the asphalt mixture is transported to the site in a heated truck, and the paving crew uses specialized equipment to spread and compact the mixture to the desired thickness. As the asphalt mixture is laid down, it is compacted with heavy rollers to ensure that it is tightly packed and level. This compaction process is important for ensuring that the pavement is strong and durable, and that it can withstand the heavy traffic loads that it will be subjected to. After the pavement has been laid and compacted, it must be allowed to cool and cure before it can be opened to traffic. During this time, the pavement will continue to harden and develop its final strength and durability. Hot mix asphalt paving is a popular choice for many pavement applications due to its durability, flexibility, and resistance to weathering and other environmental factors. It is commonly used for roadways, parking lots, and other high-traffic areas, and can be designed to meet specific performance requirements based on the intended use and location of the pavement. |
Base Stabilization |
Granular base repairs are a road maintenance activity that involves repairing or replacing the base layer of a roadway that has been damaged or deteriorated. The base layer is the layer of material that sits beneath the asphalt surface and provides support and stability to the roadway structure. Granular base repairs are typically used on roads that have widespread areas of damage or deterioration, or that are experiencing problems such as subsidence or settlement. The process involves removing the damaged or deteriorated section of the base layer and replacing it with new granular material, such as crushed stone or gravel. The repair process begins with identifying the damaged or deteriorated section of the base layer and removing the damaged material using specialized equipment such as a backhoe or excavator. The area is then compacted to ensure a stable base, and new granular material is added to fill in the void left by the removed material. Once the new material has been added, it is compacted to ensure that it is tightly packed and level, and the surface is graded to ensure a smooth, even surface. The repaired section is then covered with a layer of asphalt or other surface material to complete the road surface. Granular base repairs are an important part of a comprehensive road maintenance program, as they help to prevent further damage to the road surface and ensure the long-term durability and safety of the roadway. Properly maintained base layers can also help to reduce the frequency and cost of more extensive repairs or reconstruction efforts in the future. |
