Abstract:

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 the following 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 as follows 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 elastomericacrylic blends are as follows 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, 0 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.
