ENGINEERING PERFORMANCE OF SELECTED PROPERTIES OF UMM AL-JAMAL BASALTIC ROCKS, NE JORDAN
The main objective of this research is to study the engineering properties of Umm Al-Jamal basalt rocks. The basaltic rocks in Jordan are mainly of Tertiary - Quaternary age.
They occupy 18 % of Jordan.
Physical and mechanical tests were done on samples of basaltic rocks of Umm Al-Jamal. Umm Al-Jamal basalt has consisted of eight thickly basaltic flows with a total thickness up to 300m. It was concluded that the physical-mechanical properties of the studied samples significantly influenced by their textures and hence the rock textures can be used as a preliminary predictive tool for assessing the performance of basalt in relation to specific manners and classified as 3-4 class type. They are characterized by high-density values and exhibit very low absorption percentages which fit well with the classification schemes of the international and local specification.
