Trafik ve Yol Yüzeyi Özelliklerinin Katmanlı Kaplamaların Elastik Davranışına Etkisi

Bu yazıda, farklı katmanlı yol kaplamalarının genel elastik özelliklerini sunuyoruz. Mikromekanik teori ve Voigt / Reuss ve Hashin-Strikman sınırlarını kullanarak, kompozit ortamın sertliğini karakterize eden tüm elastik modülleri belirleriz. İspanyol Karayolu İdaresi'nin kaldırım bölümlerinin sınıflandırmasını takiben, bu belgede kapsanan durumlardan herhangi birinin bileşimine ve trafik türüne göre etkili elastik davranışını ayrıntılı olarak sunacağız. Farklı kaplama türlerini yöneten mekanizmaları incelemek için çok sayıda deneysel ve laboratuvar çalışması geliştirilmiş olsa da, açıkça belirlendikleri çok az çalışma vardır. Bu nedenle, bu çalışmanın temel yeniliği, kaplamanın performansını, onu oluşturan malzemeler ve maruz kaldığı trafik yüklerine göre ölçebilen analitik yöntemler sunmaktır. Bazı senaryolarda şemanın uygulanmasını, farklı elastik modülünün katmanlı kompozit kaplamayı oluşturan farklı malzemelerin hacim fraksiyonuna bağımlılığını göstererek gösteriyoruz.

Influence of Traffic and Road Surface Materials on Elastic Behavior of Layered Pavements

In this paper the overall elastic properties of different layered road pavements have been presented. Using micromechanical theory and the Voigt/Reuss and Hashin-Shtrikman bounds, all the elastic moduli that characterize the stiffness of the composite medium are determined. Following the Spanish Highway Administration classification of the pavement sections, this work presents in detail the effective elastic behavior of any of the cases covered by this document from their composition and the type of traffic. Although numerous experimental and laboratory works have been developed to study the mechanisms that govern different types of pavements, there are few works where they are explicitly determined. That is why the main novelty of this work consists in presenting analytical methods capable of quantifying the performance of the pavement based on the materials that compose it and the traffic loads to which it is subjected. The proposed scheme is implemented in some scenarios by showing the dependence of the different elastic modulus on the volume fraction of the different materials that made the layered composite pavement.
