This report describes the tasks of research conducted to identify effective pavement marking practices for seal coat and hot-mix asphalt (HMAC) pavements in Texas. The researchers reviewed literature, determined current Texas Department of Transportation (TxDOT) and alternative pavement marking practices, and evaluated various pavement marking treatments in the field. The researchers identified few shortcomings related to pavement marking practices on HMAC pavement surfaces. However, for seal coat pavement surface, numerous opportunities for improving pavement marking quality were identified. Based on the research findings, numerous recommendations were developed, which pertain to thermoplastic application on seal coat and HMAC, water based paint application on seal coat, seal coat aggregates, surface glass beads and field inspection. The recommendations include: apply thermoplastic at a minimum thickness of 100 mil for all longitudinal pavement markings on new seal coat when no other durable marking exists; apply thermoplastic at a maximum thickness of 90 mil for all longitudinal pavement markings on HMAC when no other durable marking exists; and water based paint may be used on a new seal coat surface in either of the following situations: as temporary pavement marking for up to six months, or as surface primer prior to thermoplastic application.
