Using a remixing MTV has what effect on temperature and segregation?

When a remixing mobile asphalt treatment vehicle (MTV) is utilized, its primary function is to ensure the uniform mixing of the asphalt material. This process generally serves to help maintain consistent temperature levels by reintroducing controlled heating to the asphalt mix.

One of the notable impacts of using an MTV is the stabilization of the temperature of the hot mix asphalt. This aspect is critical because maintaining an optimal temperature helps in minimizing thermal segregation, which can occur when various components of the asphalt mix separate due to temperature disparities.

While it might seem tempting to think that using an MTV could result in a significant decrease in temperature, the primary goal is to prevent temperature loss and assist in achieving a homogeneous mix. A stable and adequately heated mixture helps to prevent segregation, allowing for better compaction and ultimately enhancing the performance of the pavement.

Therefore, the correct choice highlights the concern regarding temperature management and segregation control, indicating that while the remixing process might seem to lead to a significant temperature drop, it’s more involved in the balancing and managing temperature to reduce segregation effectively. This understanding is essential when considering the role of remixing technologies in asphalt paving operations.
