摘要：

In this research, the effect produced by a temperature change on a flexible pavement deflection is analysed. Deflection tests were carried out on a road at different temperatures. The equipment used to measure pavement deflections was a curviameter. Based on the results of this experimental study, a methodology was established to define the experimental pavement temperature adjustment factors for deflection. In addition, the pavement structure studied was modelled, by means of a multilayer system, to calculate the deflections that would be produced below the load application point and, next, calculating the corresponding theoretical pavement temperature adjustment factors for deflection. Finally, the results obtained from the experimental study, theoretical analysis and main existing models are compared. The statistical analysis performed shows a good agreement between the experimental and theoretical obtained factors. (C) 2011 Elsevier Ltd. All rights reserved.
