Randomized trial evaluates road performance in fluid mastic asphalt mixtures, indicating enhanced durability and stability.

The study aims to design parameters for fluid mastic asphalt mixtures and evaluate their road performance.
Proposed the FMA-13 with six different asphalt–aggregate ratios.
Conducted one-sided compaction, Schellenberg asphalt leakage, and rutting tests.
Measured high-temperature stability, low-temperature crack resistance, water damage resistance, and skid resistance durability.
FMA-13 achieved less than 1% air voids, indicating effective filling of aggregate voids.
Dynamic stability was stable across asphalt–aggregate ratios of 7.0% to 9.0%, with high-temperature stability deemed excellent.
Low-temperature crack resistance improved significantly—over twice that of traditional mixtures, confirming excellent water damage resistance at 99%.

Zheng et al. (2026) studied this question.
