Winter Maintenance
The Colorado Department of Transportation (CDOT) is continuing to hire candidates to drive snowplows and complete highway maintenance work this winter, as part of the 100+ permanent and seasonal maintenance positions the agency is opening up.
The 100 workers needed makes up a little more than 10...
The topic of winter maintenance is a hair's breadth from being perhaps the apex topic for transportation agencies, notably in the Midwest. In an effort to be ready for whatever Mother Nature hurls at them this winter, the Iowa Department of Transportation (IDOT) has announced it intends on hiring...

It’s a dry heat.
So goes the unofficial mantra for all things weather in Arizona. To the unacquainted, the Grand Canyon State is an endless season of 100°+ days and 75° nights with nary a snowflake in sight. Winters are the stuff of warm vacation dreams where sitting poolside at five-star...
In Lake County, Ohio, winter weather spells trouble for a stretch of I-90 between S.R. 528 and S.R. 44.
Over a 10-year span, more than 800 winter crashes were recorded along this corridor. On Dec. 8, 2016, an intense snow band that produced massive squalls contributed to a bus crash that led to a...

From 2000-2017 our community exploded, its population more than doubling. In 2000, we had 37,000 residents and 120 center-lane miles. In 2017, we had 92,000 residents, 383...
Anyone living in a snowbelt state, where pothole dodging has become a survival skill, realizes we have serious issues with our roads and bridges.
And what the public is becoming increasingly aware of is that winter maintenance salting is largely the cause. Less obvious, but of equal concern, is...
Those of us who work in areas with inclement winter weather know how important proper winter storm response can be. While only a part of our overall road maintenance responsibilities, our effectiveness when dealing with snow and ice events is certainly the most scrutinized. Nine months of great...
Clearing snow from roadways is an effort as old as roadways themselves, at least in cold climates.
Truck-mounted plows came into wide use in the 1920s. Abrasives such as sand, coal bottom ash or clinker were used to increase friction on icy roadways, once plowed. During the winter of 1941-42, New...

In snowy states, winter maintenance crews deal with everything from freezing rain and black ice to blizzards and even avalanches.
To prepare plow drivers for whatever Mother Nature has in store, state DOTs and other agencies kick off each winter season with training classes.
While all states...
In this video from the Mississippi Department of Transportation (MDOT), Melinda McGrath, P.E., executive director of MDOT, answers questions about the process for pre-treating and maintaining roadways during a winter weather event. Mississippi is currently experiencing ice on roads and bridges in...

“Winter isn’t over til it’s summer.”
That’s the story heard from winter maintenance workers out on the roads in the Cascade Mountains in Oregon, as the mountain range sees snowfall from as early as September to as late as May. It is in this region that most of the snowplows in the state of Oregon...

The city of St. Cloud and county of Anoka in Minnesota were both looking to enhance the performance of their salt brine operations. In 2015, St. Cloud used over 81,000 gal of salt brine and purchased 2,290 tons of salt. Anoka County is responsible for maintaining and clearing snow and ice from 423...
Researchers from Drexel University, Purdue University and Oregon State University have discovered that adding paraffin oil to the mix for road concrete can give it the ability to melt ice and snow when temperatures fall.

Drexel University researchers have recently made a discovery that could create roads that deice themselves during winter storms. The secret? Adding a little paraffin wax to the road's concrete mix.
In a paper published for the journal Cement and Concrete Composites, researchers, led by Yaghoob...
If you have ever built anything, you have probably heard the old saying, “Measure twice, cut once.”
The first time you did not follow it, you quickly learned the lesson. Making an accurate measurement is important, otherwise you end up wasting time. If you think of weather, have you ever wondered...
