Considerable knowledge of pavement behaviour under static loads is available world-wide. The behaviour of concrete pavements under dynamic loads, however, has not received much attention and hence is not well understood at present. To address this need, a 3D finite element analysis using diverse axle groups with different speeds from 2 km/h to 110 km/h has been performed. Two pavement types namely, jointed plain concrete pavement (JPCP) and jointed reinforced concrete pavement (JRCP) are investigated. Maximum dynamic tensile stresses and deflections influence lines are presented to demonstrate the pavement response, and calibrated against existing results.
Critical speed and dynamic amplification are also determined as well as critical location of fatigue cracking. Results indicate that dynamic analysis is essential for pavement design, particularly for JPCP.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
