Rubber modification can improve elasticity, crack resistance, and fatigue performance, which helps slurry systems tolerate movement and reduce reflective cracking. It also tends to increase viscosity and shear sensitivity, so mix design windows become narrower and equipment must handle thicker material without breaking the emulsion. You may need stronger agitation control, larger pump clearances, and tighter filtration to avoid nozzle clogging. Cure behavior can change, so setting control additives and weather planning become more important. Quality control should include residue elasticity indicators and consistency checks.
