Automatic flow controls are generally situated:

Automatic flow controls are typically located near the auger tip because this placement allows for real-time adjustments to the flow of hot mix asphalt as it is being laid down. By positioning the flow controls close to the auger, operators can effectively manage the material feeding process. This location provides immediate feedback and helps ensure that the correct volume of asphalt is delivered consistently to the screed. The auger tip is crucial for distributing the mix evenly across the width of the paving operation, so having the flow control mechanisms here facilitates better control over the material application, contributing to a more uniform surface and enhancing the overall quality of the asphalt pavement.

In contrast, other options like the hopper, screed, or tow point may not offer the same level of responsiveness to changes in the flow requirements, which is essential for high-quality pavement performance.
