The 3D panels are a new system of construction. This system is used as wall and ceiling in buildings. The structural behavior of 3D panels is dependent on the strength and rigidity of connector elements. In this article flexural and shear tests have been conducted on six 3D panels. The results have been compared with results of finite element software, ANSYS. The details and results of the test program are described, and the observed behaviour patterns are discussed.<\div>

Phenomena related to the fatigue behavior of pavements are among the most important concerns confronting pavement designers. Damage caused by pavement fatigue requires large amounts of money to be budgeted for the maintenance and rehabilitation of highway and airport pavements, and this expenditure motivates research into methods to reduce the fatigue damage. One of these proposed solutions is the inclusion of waste materials in the material used for pavement construction to increase its strength against dynamic loading. Many models have been developed for predicting the fatigue behaviour of asphalt concrete pavements, but none exist for asphalt mixtures modified by the addition of waste materials. This paper presents the first model of the fatigue behaviour of glass–asphalt (glasphalt) mixtures, which is able to describe the fatigue behaviour of glasphalt under dynamic loading. The proposed model is then compared with a number of previously suggested models for the behaviour of Hot Mix Asphalt (HMA). Glasphalt concrete mixtures are shown to have a longer fatigue life than HMA.
