The transition from hot mix asphalt (HMA) to warm mix asphalt (WMA) is inevitable. Starting January 1, 2025, WMA will be the new standard, replacing many current asphalt products.

However, it is an uncharted territory regarding how to get the best road quality with WMA. Unlike the well-established knowledge of HMA construction, there is a significant lack of understanding about achieving high pavement quality with WMA. The different material characteristics make it hard to transfer knowledge from HMA to WMA. This lack of expertise complicates creating clear plans to minimize construction variability and avoid over-planning.

Addressing this issue is crucial because adapting to the transition to WMA depends on building solid knowledge. This helps contractors meet quality standards, follow new regulations, and support sustainable road construction.

Therefore, we need a planning tool that accounts for WMA's unique properties, to remain effective in future asphalt construction.

To make the planning tool relevant…
