Parking lot striping involves real technical questions: how different paints perform on aged asphalt, how retroreflectivity degrades over time, which application methods hold up in high-traffic areas, where ADA layouts most commonly fail inspection.

Contractors have answers to these questions. They have tested them the hard way, job by job. But that knowledge lives in individual experience, not in published research that the rest of the industry can use.

PLSIC™ publishes original research on the materials, methods, and risk factors specific to parking lot striping. Papers are developed in collaboration with experienced contractors and material science professionals. Findings are available to members through the document library.

The first PLSIC research publications are in development and will publish alongside the PLSIC-2027 standards series.
