First introduced nearly 35 years ago, small surface planers (scarifiers) have seen their acceptance and use on municipal maintenance projects grow significantly.
GIS has proven to be a versatile tool for integrating the information technology and data investments within organizations. Combing these historic data with current information on pavement conditions provides a data foundation for integrating a pavement management system (PMS) application into a...
Many municipal public works agencies know the benefits of having an automated vehicle location (AVL) system to monitor employee performance, improve operational efficiency, and increase public communication efforts. But another little-known benefit is being able to map the discrete locations of...
Roller-compacted concrete (RCC) is just what it sounds like. This stiff, zero-slump concrete mixture can be placed with asphalt-type paving equipment and then compacted with rollers.
Now that energy prices are rising, with infrastructure budgets not yet adjusted to keep up with the increases, it is time look for ways to amplify our reuse of asphalt pavements where possible.
Compost's benefits to soils are physical, chemical, and biological. Physical benefits include improved soil structure and improved moisture management (both higher moisture capacity and higher infiltration).
Even when relevant information is within a database, the geographic references often lack the necessary coordinates. Only when both the structured and unstructured information is fused into a single, cohesive view can you get the complete picture needed to make an informed decision.
By following simple guidelines, public works managers can attain quality and efficiency without hurting the bottom line.
A vehicle lift is the express lane to faster fleet repair, but don't take our word for it: Studies show a lift can save a facility more than $100,000 per year in labor costs.
Storm delays can result in substantial costs. But the variety of pumps available makes them an ideal tool for residential, commercial, and industrial applications— ranging from basement and landfill dewatering to wastewater treatment facilities and even food-processing plants.
Concrete bridges are major investments and critical to local transportation systems, but traffic, trauma, and exposure to the elements can cause them to deteriorate. That's why prudent owners schedule periodic evaluations to ensure bridges function safely
