You may have seen a fleet of vans with external cameras, radars and other devices driving around town. These vans work to improve the condition of the roads in Durham.

The vans, equipped with a host of data collection devices, collect and compile information about each street maintained by Durham Public Works to help plan street maintenance funding. The project is called the Pavement Condition Survey.

Durham Public Works awarded a contract to the private company Roadway Asset Services (RAS) to “assess the condition of the streets and develop recommendations for pavement repairs”.

The City’s Public Works Department “will use this information to more effectively plan and manage the maintenance of City-owned streets,” according to a City of Durham news flash.

This index occurs about every four to five years, according to Durham Public Works. The latest clue took place in 2018 and collected nearly 740 miles of road data. Additionally, in 2018, Durham Public Works set aside $ 7 million in public funds for street maintenance.

This current investigation will have similar effects on Durham’s infrastructure.

Durham Public Works announced the project on June 28, construction began in July, and the project is scheduled to end in October. In October, RAS will formulate its proposal for the next few years of maintenance of the public road.

RAS currently uses its specialized vans to sweep the city streets. The cameras and scanners were programmed to “create an inventory of digital data on the condition of City-owned streets”, down to the type of distress found in the roadway.

After taking an image, the data is compiled and the mapping identifies problematic locations in the city. This information is used to create an infrastructure plan.

Streets are assigned a numerical score between 0 and 100 and are classified into five different categories: “good”, “satisfactory”, “average”, “poor” and “failed”.

A “good” street scores between 86 and 100, while a “failed” street is between 0 and 25. The average score for roads assessed in the 2018 survey was 69, indicating “correct” street conditions. Individual street scores are available on this digital map created by Durham Public Works.

The company in charge of the 2018 pavement survey advised Public Works on a “10-year $ 10 million (optimization) funding scenario,” which “[developed] a ten-year long-term pavement maintenance and preservation program ”with the city’s $ 7 million street maintenance allowance.

This plan kept the street scores at an average of 72, or “satisfactory” conditions, devoting 30% of the fund to preservation and 70% to rehabilitation, first performing the maintenance of the individual streets with the scores. the highest.

The successes and failures of this plan will be represented in the 2021 index. This allows the city to decide on the actions to be taken, as the 2018 plan is re-evaluated, in the preservation of public roads in their state. current.
