• Abstract:
  This report is the third in a series of four, and it presents the procedures and results of various studies conducted to determine (1) the causes of marker retention failures, and (2) possible counter measures to increase the service life of the markers and traffic buttons. It was clearly established that marker retention is an inverse function of the number of tire hits. Truck tires, especially high pressure tires are particularly damaging. So one of the recommended marker retention categories was to place the reflective markers behind the sol id paint stripe they supplement, thus protecting them from many hits. Because of rapid loss rates, resulting in poor cost- benefit ratios, it is suggested the markers not be used to supplement lane line stripes on asphalt surfaces. The plastic 2x4 markers are the poorest performers, so far as retention is concerned, and should not be considered for Texas highways. The oval shaped ceramic markers proved to be the best performers on all paving material so far as retention is concerned. This was especially true when the markers were manufactured with small, round studs on the bond surface as originally suggested by Mr. H. D. Jones, District 12.
