Also, SDDOTs present pavement marking system(s) can not endure the traffic experienced in urban areas, much less urban areas when snow removal techniques are being implemented. SDDOTs high traffic urban areas presently require that pavement markings be re-painted 3 to 4 times during the warmer months each year. As well, in a last ditch effort to have pavement markings in urban areas prior to winter, markings may be placed as late as November. Markings placed this late in the season are likely to be placed when temperatures are below the specified minimums causing the markings to fail prematurely.
SDDOT needs to evaluate new high performance pavement marking systems and application techniques to determine which systems would: meet the EPAs 1996 VOC requirements; minimize the number of times pavement markings need to be reapplied each year; better endure snow removal techniques; be cost effective for both urban and rural areas.
