Preliminary Evaluation of Pavement Surface Distresses Related to Pavement Markings

Lucio Salles & Lev Khazanovich IRISE ANNUAL MEETING MAY 24, 2021

1 University of Pittsburgh | Swanson School of Engineering

The Research Problem

Reports of pavement distresses, such as cracking and raveling, under or along pavement markings

Romero and Brown, 2010

University of Pittsburgh | Swanson School of Engineering

Possible Causes Poor asphalt compaction near longitudinal joint Trapped moisture under marking

Romero and Brown, 2010

Differences in surface temperature

Marking Material Surface type

Parry and Kemp, 2007
