How Does Spring Thaw Affect my Parking Lot?

Spring thaw, also known as thaw weakening, occurs in early spring when the temperatures are beginning to rise, and the snow begins to melt. Spring thaw is also the time when the most damage to asphalt pavements can occur. During the winter, water within the pavement and aggregate base freezes from the surface of the pavement down to the subgrade. Spring thaw occurs as the frozen pavement begins to thaw from the surface of the pavement down to the subgrade. While the subgrade is still frozen, water from the thawing pavement is trapped in the materials below the pavement. These saturated materials are significantly weaker, allowing heavy loads to easily damage the pavement. This is why many states implement spring load restrictions. The Minnesota state DOT (MnDOT) has estimated over $10,000,000 in savings each year, due to the implementation of the spring load restriction program.

Providing Customers with the Best Pavement Solutions: A Case Study

During the summer of 2017, Bituminous Roadways, Inc. (BR), was contracted to reconstruct the parking lot for a busy fitness center in the southern Twin Cities metro area. L.A. Fitness management communicated with BR the desire to continue full operation during construction. Due to the extensive nature of this project, BR recommended a two-phase approach. Phasing a project isn’t necessarily an obstacle, but it does take some planning and can present some challenges. The parking area was divided into two sections. When BR was working in the first area, barricades were used to indicate to fitness members where they could park. After the first phase was completed, the barricades were switched and users were able to park on the freshly paved asphalt parking lot while BR completed the second section.

How Freeze-Thaw Cycles Can Damage Asphalt Pavement

Winter is a “hard” time for asphalt pavements, literally. Asphalt pavements are produced and constructed at high temperatures when the asphalt binder is a liquid so it can be easily mixed with the rocks and sand. During the spring, summer, and fall seasons, asphalt is flexible and stretchy in the warm weather, helping to prevent cracks from forming. However, as temperatures decrease during winter, the asphalt becomes harder and stronger, but also more brittle. Extreme cold temperatures can cause pavements to crack, but the most damage to pavements is caused by freeze-thaw cycles.

What do spring load restrictions have to do with asphalt?

Since 1937, Minnesota has enforced spring load restrictions each year as temperatures begin to rise. These spring load restrictions are determined for each state, county and city road, and they restrict the weight of a single axle to less than 5-10 tons. This restriction will not affect any commuter vehicles, but it does have a big impact on commercial vehicles.
