For which lanes should MTV be utilized when placing the surface mix?

The correct choice indicates that MTV (Material Transfer Vehicle) should be utilized for all ramps, loops, and travel lanes greater than 1,000 ft in length. This is because the MTV plays a crucial role in ensuring a high-quality surface mix is laid down. Its use helps to maintain a consistent flow of material, reduces segregation of the mix, and improves the overall quality of the pavement by minimizing temperature differentials during the placement process.

Utilizing an MTV for all ramps and longer travel lanes is especially important due to the need for uniformity in the asphalt application. Longer lanes and areas such as ramps and loops are more susceptible to temperature variations and disruptions if not handled properly; the MTV helps to mitigate these issues.

When considering the other options, it’s clear that using an MTV only for full-width travel lanes would be insufficient for achieving the desired consistency across various road elements. Limiting the use of MTV to only collector lanes would neglect the benefits it offers in longer and complex configurations like ramps and loops that require more attention. Similarly, excluding residential driveways from this practice might overlook areas where asphalt consistency is just as critical, but these locations typically do not warrant the same requirements as longer travel lanes or complex intersections. Thus, the comprehensive application of
