Influence of static and impact load on pavement performance

Abstract

The most researches are done for evaluation of dynamic load of vehicles on pavement response. However, pavements of airports, container terminals, logistic terminals, areas of storage, industrial areas, parking lots, areas operated by falling materials or special machinery and etc. are affected by long term static or impact load. Due to this kind of loading specificity, pavement performance is different comparing to pavement performance operated by repeating dynamic traffic loads. Practice shows, that permanent (plastic) deformations and thermal cracks often appear in such pavements. Consequently, the loading specification of areas affected by static and impact load, development of permanent deformations and thermal cracking and analysis of practice and normative requirements for pavements affected by static and impact load were considered in this research. The research has resulted in serviceable solutions for pavement structures resistant to static and impact loading according to the type of pavement (flexible, rigid, semi-rigid (flexible)) and the scope of application.
