Abstract: To address shrinkage cracking in cement-stabilized macadam(CSM), redispersible latex powder was added with five different dosages, setting a control group for comparison. Experimental investigations included road performance tests, SEM analysis, and uniaxial compression tests with acoustic emission (AE) monitoring. Mechanical properties and AE parameter analyses revealed that redispersible latex powder induces film-formation and pore-filling in CSM. The 4% dosage improves mechanical performance by enhancing strength and deformation capacity. The AE amplitude-duration scatter plots show increased high-amplitude, short-duration events and a dispersed peak frequency distribution with eleva-ted high-frequency components. Under uniaxial compression, CSM damage evolves in three stages. Redispersible latex powder shortens the initial compaction stage, reducing energy accumulation. In the elastic stage, steeper load curves and higher cumulative energy blurred the transition to plastic damage. Accumulated energy increased by 7% compared to the control. These results indicate that a 4% dosage enhances CSM toughness and crack resistance by optimizing microstructural interactions and energy dissipation during loading.
