Asphalt Speed Bumps are the most common type of speed bump installed in the world today, and for good reason. Asphalt speed bumps are very durable, quite effective and can be resealed and repainted each year to keep them looking fresh and noticeable. They help reduce traffic speeds and control the flow of traffic in your parking lot. Although asphalt speed bump installation is more expensive than installing rubber or plastic speed bumps, asphalt speed bumps are a permanent fixture and cannot be easily removed or damaged.
