RISAccounting for Censoring and Unobserved Heterogeneity in Pavement Cracking
Publisher: American Society of Civil Engineers
Abstract: Most fatigue cracking models in use have been developed using the ordinary least squares (OLS) method. However, fatigue cracking data (or any type of cracking data) consists of censored data since it has a lower limit of ...
Mechanistic-Empirical IRI Model Accounting for Potential Bias
Publisher: American Society of Civil Engineers
Abstract: The roughness prediction models in the International Roughness Index (IRI) currently incorporated into the Mechanistic-Empirical Pavement Design Guide (M-E PDG) have been developed by means of ordinary least squares (OLS). ...
On the Stabilizing Effect of Weigh Stations on Truck Equivalency Factors for Pavement Design
Publisher: ASCE
Abstract: In Costa Rica, weigh stations for trucks and commercial vehicles were reinstated in 2008. Since then, a stabilizing trend in the percentage of heavy vehicles with excess loading was observed. For pavement design purposes, ...
Rutting and Fatigue Behaviors of Shingle-Modified Asphalt Binders
Publisher: American Society of Civil Engineers
Abstract: The recycling of asphalt shingles in flexible pavements has received considerable interest in recent years for economic, environmental, and social reasons. The objective of this study was to evaluate the effects of adding ...
