Abstract:

Thermoplastic striping material can be used as a pavement-marking system and has several advantages over other systems; however, it also has the disadvantage that, in some cases, the entire systems is lost prematurely. These failures have been attributed to faulty application procedures. This paper examines four important possible application criteria--the temperature of the molten thermoplastic material, the air temperature, the pavement temperature, and the moisture condition of the pavement--for inclusion in a specification. A minimum bond strength necessary to ensure an acceptable service life of the material of 862 kPa (125 lbf/sq in) is suggested. It was concluded that (a) the temperature of the thermoplastic material at application is important, and a small range should be specified based on test results; (b) the air temperature does not affect the bond strength and should not be included in a specification; (c) the temperature of the pavement is an important criterion, and no thermoplastic material should be applied to pavements colder than 12.8 deg C (55 deg F); and (d) the moisture in the pavement has relatively little effect on the adhesion, and thermoplastic may be applied to any surface-dry pavement. /Author/
