Protection of expansion joints from snow plow damage is one of the critical factors that keep the joint's service functioning as per initially designed specifications.

Several examples of snow plow damages are being seen, causing damages to the expansion joints, and as a result replacement of joints comes across costs millions of dollars each year.

Expansion joint replacement is not only costly but it affects people's lives, traffic jams, and even in some cases the authorities are not able to close the road to traffic due to the high volume of cars and not having an alternative route.

Snow removal should not be underestimated extra precautions should be taken into account, here are the guidelines for snow removal.

1. Snow plow blades should not come in direct contact with expansion joints,

2. The best action to be taken is to remove snow from the expansion joints either by sweeping, shoveling, or snow-blowing if possible.

3. Plow blades should be arranged at least 1.5cm above the asphalt/paving level when crossing the expansion joints

4. The blades must be equipped with well-maintained rubber tips to minimize impact damage to the expansion joints.

5. We recommend that the location of the joints be clearly marked, and the plow drivers be instructed to lift their plows slightly(around 1.5cm) when crossing the expansion joints.

6. Snow plow drivers should be instructed to reduce their speed when approaching the ramps.

7. If the snow plowing job is subcontracted, the authority should include that the snow plowing contractor is responsible for any damage to the expansion joints caused by plowing not in accordance with the recommendations here and for all expenses that may be incurred in repairs of the joints.

In conclusion, giving extra precautions in snow removal would save the service life of expansion joints and avoid a significant amount of expenses.
