What is the proper head of asphalt material in front of the screed being mixed by the augers?

The correct answer is that the proper head of asphalt material should be at the center of the auger shaft. Maintaining the asphalt material at this position is essential for ensuring a uniform distribution of asphalt as it moves towards the screed. This central placement allows the augers to efficiently draw the material into the screed, which is crucial for achieving a consistent mat thickness and quality during the paving process.

When the head of material is positioned at the center, the augers can effectively mix and convey the asphalt to the screed without leaving gaps or resulting in uneven flow. It helps in providing a steady and consistent supply of material, which is vital for maintaining the quality of the asphalt pavement being laid.

If the material were to be at the front or the rear of the auger shaft, it could lead to complications such as uneven distribution or possible segregation of the asphalt mix, resulting in issues with the final pavement quality. Having no head of material would also be problematic, as it would hinder the augers’ ability to convey the asphalt to the screed, stalling the paving operation. Thus, having the material centrally located is crucial for optimal performance and output.
