My deepest gratitude goes to my supervisors Dr. Nicolas Saunier, and Dr. Luis Miranda-Moreno for their patience and guidance. My persistent questions and showing up at their office were always rewarded with insightful responses and constructive feedback. I am very lucky to have worked with these remarkable researchers and mentors. Through an international doctoral exchange, I had the fortune of working with Dr. Aliaksei Laureshyn at Lund University, Sweden. The experience was inspiring and memorable. I would like to thank the Fonds de recherche du Québec - Nature et technologies (FRQNT) grant 2015-NC-180344 and the National Science and Research Council (NSERC), grant 2017-06115 for their financial support, as well as the City of Montréal and boroughs that authorized the data collection. -

A Study of Occurrence of Potholes and Washboards on Soil-Aggregate Roads EUGENE Y
A Study of Occurrence of Potholes and Washboards on Soil-Aggregate Roads EUGENE Y. HUANG, Associate Professor of Civil Engineering, University of Illinois This report presents the results of a study aimed at determining some of the circumstances associated with the occurrence of potholes and washboards on soil-aggregate roads. The study consisted of a statistical analysis of the qualitative data obtained from a road condition survey involving road surfaces of the coarse-graded aggregate type composed of mineral aggregate such as gravel or crushed stone and some binder material. Results of the study indicate that the occurrence of potholes and washboards was definitely associated with the volume of traffic, the type of surface material, and the drainage condition of the road surface. Although the findings are admittedly limited to the types and conditions of the roads studied, it is hoped that the data may be of value in further understanding the formation of potholes and washboards. • THE OCCURRENCE of potholes and washboards has long been a serious problem in soil-aggregate surfaces. These formations, however, have not been fully explained. Potholes on road surfaces are irregularly occurring, well-defined holes consisting of fairly deep cavities up to about 5 in. (Fig. 1). Washboards are transverse or nearly transverse waves on road surfaces, generally about 1 to 1/4 in. in amplitude andspaced about 2 or 3 ft apart (Fig. 2), regardless of the nature of material in which they occur. (Although typical formations of potholes and washboards are readily distinguishable, there are, however, numerous possibilities of transitional forms between these two typical forms.) Both potholes and washboards are conducive to surface impact and vibration, which contribute in a great measure to the rapid deterioration of the road surface as well as the vehicle itself. -
