Research on Relationship between Riding Quality and Pavement Distress of Asphalt Pavement

Abstract

For asphalt pavement performance evaluation, pavement roughness, which is subject to cracks, potholes, road repairs and so on, is a major factor to influence riding quality. Therefore, riding quality is partly correlated with pavement distress, and the relationship can be transformed to that between pavement roughness and distress rate. However, this relationship is not clear, and not reflected in existing evaluation models. Thus, correlation analysis and non-parametric test of independent samples were applied in this paper to find that, international roughness index and pavement distress rate are significantly different due to different grades of roads, then, linear and nonlinear regression were used to analyze the relationships between international roughness index and pavement distress rate for different road grades. Furthermore, original data were processed by logarithmic transformation, radical transformation, exponential transformation and so on, based on which, corresponding relationships were analyzed by linear and nonlinear regression. Finally, best models to describe relationships between international roughness index and pavement distress rate for different road grades were solved out, and corresponding 90% confidence intervals were computed. Research in this paper offers a reference for improving asphalt pavement performance evaluation system and models, which is conducive to further theoretical research and practice.

“…Jalan merupakan prasarana transportasi yang berpengaruh dalam menentukan pertumbuhan ekonomi pada suatu daerah yang dapat meningkatkan kenaikan jumlah pergerakan distribusi barang dan jasa (Fibrian, 2020;Alfianti, 2017). Peningkatan volume maupun berat muatan yang membebani jalan menjadi salah satu penyebab overloading maupun kerusakan pada suatu perkerasan jalan selama umur layan (Peng, 2012;Mulyono, 2013;Fibrian,2020).

Mechanical Characteristics of Asphalt Pavement Pothole Maintenance

“…Potholes are one of the most common diseases of asphalt pavement, and they will affect the comfort and safety of driving, if it not repaired in time [1,2]. At present, the maintenance methods of asphalt pavement potholes are generally divided into cold repair, hot repair, and hot regeneration repair.…”
