Given the complexity of field conditions, some aspects of liquid performance may seem to be a “black box,” and at times it can be difficult to know how to best use them based upon field experience alone. This challenge is increased by the fact that we use liquids in a variety of ways, from anti-icing to pre-wetting to direct liquid application (DLA) deicing, and liquids perform differently depending on the application. This presentation will show how we can apply the basic science of liquid deicers to complement our field-based knowledge to better select the right liquid and rate for different conditions and application types. Topics will include how liquids perform differently in anti-icing, pre-wetting, and DLA; the important liquid properties for these different types of application; how we can utilize freezing point curves as powerful tools to predict liquid performance; and how we can apply the basic science to guide the use and expectations of brine additives and blends.

The speaker will present details of Fairfax County’s journey to successful salt reduction program development and implementation, along with best management practices.
Read MoreWith everyone’s budgets getting tighter and public expectations at an all-time high, an effective and efficient method of tracking and communicating winter operations is needed. Every agency has performance measures whether they know it or not as agencies typically track staff hours, material usage, road network level-of-service, operational response time, collisions, and much more. In this session, the speaker will discuss how the City of St. Paul has developed formal performance measures to help manage and improve work, safety, budget, performance, and sustainability.

This session is designed to help your organization identify what you actually need, successfully manage, and sustain a long-term plow truck program.
Read MoreColumbus Department of Public Utilities (DPU) implemented the business case evaluation (BCE) process and avoided over $70 million in costs after seven years. The added social and environmental value of conducting BCE’s brings the cost avoidance to $100 million, and service levels, safety, and risk exposure improved. The BCE process received international recognition from the Water Services Association of Australia. It was featured in a McGraw-Hill Report, “Water Infrastructure Asset Management: Adopting Best Practices to Enable Better Investments.” A case study, which will show how BCEs are conducted and the savings that can be realized, includes examples of monetizing social and environmental factors that have no market-driven value. At PWX21, agencies discussed the difficulties of monetizing these factors. Implementation lessons will be shared, including establishing BCE policy and avoiding common implementation problems.
Read MoreDigital maps have changed the way we drive, locate a store, or even choose a restaurant. Multi-layer GIS (geographic information system) maps are also transforming how government agencies plan and manage their infrastructure assets, report information to stakeholders, and communicate with the public. With real-world examples from city, county, and state transportation agencies, this session demonstrates how to use GIS maps to improve decision-making, performance, and operational efficiency to deliver safer longer-lasting infrastructure.
