Village of Schaumburg
Pavement Management Program
The Village of Schaumburg collected pavement distress data on regular cycles for all its maintained roadway segments. The collected data was used to develop pavement condition ratings for each roadway segment throughout the Village to measure the effectiveness of historical pavement maintenance efforts. The data collected was then processed to create a PCI (pavement condition index) score for each street segment. A high PCI score indicates pavement in good condition, and a low PCI score indicates poor pavement condition. Village staff found anomalies within the data when compared to subsequent assessments of the historical pavement condition ratings. These anomalies indicated that some pavement segment conditions were improving even though no pavement work had been performed. Additionally, while the PCI data has a particular value in understanding the relative state of Village streets, there was no effort within the scope of the historical data collection efforts to provide network-level pavement management support. In 2015, Chastain provided engineering support to the Village to ensure better data integrity and a better approach to its pavement management efforts in developing an effective annual program and strategies for repair. Working closely with Village staff and our subconsultants, we fostered a collaborative engagement to identify plan goals, evaluate existing pavement management strategies and to develop a plan that met the goals with the flexibility to respond to the Village elected officials. Our pavement management plan was developed to include the use of PAVER™ to provide greater insight into evaluating alternatives. PAVER™ is a software application developed by the Army Corps of Engineers. The software uses PCI data, cost data and repair strategies to provide optimal program solutions for pavement maintenance efforts and alternatives. These alternatives are compiled based on different budget options and different strategies. In addition, the leading cause of pavement failure on low-volume roads is water penetration and freeze/thaw. With the development of an alternate HMA design, it is better suited for |
local residential streets providing better durability and is more resistant to cracking as compared to IDOT’s standard 9.5mm surface mixture over an IDOT 19.0mm base mixture.
Lastly, several repair strategies were developed for the Village street program. Traditional strategies included basic resurfacing, patching/resurfacing and reconstruction. The program developed through our 2021 efforts added a thin overlay strategy. This strategy utilizes pavement condition input to determine candidate streets requiring no more than a surface overlay on very low volume roads and cul-de-sacs. HMA designs, as described above, have been incorporated to achieve their pavement condition goals at an overall lower cost. In 2022, we utilized PAVER™ to forecast street segments for the Village’s in-house patching efforts. Using PAVER™ data, we can identify street segments that will become a “pothole” issue so Village operation staff can proactively address these segments with their in-house efforts, which results in improved overall pavement rating. Our proven innovative strategies have established better roads and introduced lower cost repair options that extend the Village’s budget. We have also broadened their pavement preservation efforts to include a surface rejuvenator as a proactive preventative treatment. The Village uses Reclamite, a product of Corrective Asphalt Material. This product is proven to restore and preserve the durability, flexibility and viscosity properties of the asphalt pavement surface resulting in an extended life of the pavement surface. By extending pavement life, we lower operating costs associated with pavement maintenance and increase community satisfaction by introducing longer-lasting pavements. This plan is responsive and inclusive of industry best practices and the newest materials and mix designs. Our services covered ratings and programming for flexible and rigid pavements on the local street network. This plan has become a tool for the Village in the development of future budgets, selection of projects for future improvements, independent engineering support for decisions with the Village Board, and securing outside funding sources. |
