Description

Yolo County’s commitment to efficient, forward-thinking, and environmentally conscious road maintenance practices is exemplified by the success of the 2023 Pavement Preservation Project. Focused on enhancing the longevity of roads in the unincorporated rural communities and surrounding roads through sustainable approaches, this initiative strategically preserved existing infrastructure while applying innovative techniques to mitigate the need for constant maintenance.
In the past few years, the community of Clarksburg and surrounding area has experienced changes to the type of farming operations. Some of the lands have been converted from row crops to orchards, vineyards, and Wineries. The project directly improves the access to farm to fork farming operations vineyards and wineries in the area. The Pavement Condition Index (PCI) for the road included in the project ranged from 0 to 66. Deferred maintenance of the roads and changes in farming equipment have been the major contributors to the current conditions. The project was needed to create safer roads for all modes of transportation.
The project began with surface preparation, by addressing eroded areas and debris, applying a leveling hot mix asphalt as necessary. Surface imperfections were rectified through precise techniques such as surface grinding to ensure a smooth road surface. Recognizing the diverse needs of different roads, the project employed a range of preservation methods, including micro-surfacing, rubberized chip seal, and slurry seal. One notable facet of our approach is the careful consideration given to the preservation of existing elements such as survey monuments, traffic control systems, drainage inlets, utilities, and roadside signs. Our engineers developed comprehensive plans to safeguard these crucial components, ensuring they remain intact and functional while the road improvement activities took place, reducing additional costs of replacement or relocation.
The incorporation of micro-surfacing and rubberized chip seal methods brings substantial benefits to the overall efficiency and sustainability of road maintenance. Micro-surfacing, a polymer-modified emulsion and finely graded aggregate mixture, provides a protective layer, enhancing skid resistance and durability helping with both safety, smoother travel, and longevity of the road itself. Similarly, rubberized chip seal involves the application of a binder modified with recycled tire rubber, offering superior flexibility and reducing road noise. These methods offer durable and cost-effective solutions, ensuring roads are resilient to environmental stressors and traffic loads. These methods not only extend the road life but also mitigate the need for frequent maintenance interventions for a total of 20.86 miles
