National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Field Testing of Hot-Applied Traffic Paints.

PB265487

Publication Date	1977
Page Count	16
Abstract	Three heated traffic paints and the State's standard unheated paint were compared on both asphalt and portland cement concrete pavements to determine relative drying times, performance, and durability. In addition, two gradations of glass beads were applied with each paint type. All paints performed better on asphalt concrete pavement than on portland cement concrete. On asphalt concrete pavement, snow and ice contributed to accelerated wear, probably masking potential differences in durability. In these tests, the standard unheated paint performed best, while the 120F heated paint performed poorest, although the difference was not large. In areas where snow and ice do not affect durability, larger differences in durability might be encountered, which could control the choice of paint to be used.
