On what type of roadways should the MTV be used for all surface mixes regardless of binder grade?

The use of a Material Transfer Vehicle (MTV) on Interstate and U.S. routes with four or more lanes is ideal for all surface mixes, regardless of binder grade, due to several key reasons. These roadways typically experience higher traffic volumes and speeds, necessitating a smoother and more uniform surface to ensure safety and longevity of the pavement.

MTVs play a crucial role in maintaining the temperature and consistency of the asphalt mix during transportation from the paver to the surface. This is particularly important on larger, multi-lane roadways where any defect can lead to significant issues such as raveling, cracking, and ultimately, structural failure. The MTV's function helps prevent segregation of the materials, ensuring that the mix laid down is uniform and performs optimally.

Furthermore, the operational efficiency provided by an MTV on these busy routes allows for continuous paving without lengthy interruptions, which is vital in minimizing traffic disruption. This continuous flow helps to enhance the quality of the paving process and results in a better overall finished product, which is essential for maintaining public safety on major roadways.

In contrast, the other types of roadways, such as residential streets, local highways, and pedestrian walkways, do not typically require the same level of surface quality
