What is the primary function of a lute in asphalt spreading?

The primary function of a lute in asphalt spreading is to level the asphalt. A lute is a tool typically used by maintenance workers and asphalt paving crews to help create a smooth and even surface during the application of hot mix asphalt. Its design allows for precise control over the spreading of asphalt, allowing workers to spread, level, and smooth the material effectively before it cools and hardens.

When asphalt is applied, it can form uneven spots or ridges, which can lead to issues with water drainage, surface integrity, and overall appearance. Using a lute facilitates the redistribution of material to create a uniform thickness, which is crucial for the longevity and functional performance of the paved surface. This action contributes significantly to the final quality of an asphalt pavement, ensuring that it is both aesthetically pleasing and structurally sound.
