Investigation into Acrylic Paint Cracking (APC) on Asphaltic Pavements
The objective of this effort was to investigate Acrylic Paint Cracking (APC) on asphaltic pavements and to identify an APC coating solution. The investigation consisted of: (1) Site visits to asphaltic airfields, roads, and parking lots, (2) Field testing of Asphaltic Concrete (AC) and AC wearing surfaces, (3) Field and laboratory testing of six acrylic paints, and (4) Analysis of paint stresses. Findings for acrylic marking paints are: (1) High adhesion to asphaltic wearing surfaces, (2) High overcoat adhesion, (3) Poor flexibility, (4) High abrasion resistance, (5) High rates of thermal expansion, (6) Moderate paint cracking thickness, (7) High Residual Cure Stress, (8) High water absorption, (9) Moderate asphaltic bleed resistance, and (10) Coatings contribute to Acrylic Paint Cracking. Findings for elastomeric/acrylic blends are: (A) High adhesion to asphaltic wearing surfaces, (B) Excellent flexibility, (C) Moderate abrasion resistance, (D) Low rates of thermal expansion, (E) Moderate paint cracking thickness, (F) Low Residual Cure Stress, (G) Low water absorption, (H) Excellent asphaltic bleed resistance, and (I) Blends should decrease Acrylic Paint Cracking. Until new paints become commercially available, asphaltic pavements (asphaltic airfields) may be marked using TT-P-1952D formulated with a second generation acrylic resin.
