Abstract
Al-Bathan roadway connects between Nablus city and Al-Bathan village. Nablus city lies in the northern part of West Bank, it is considered as the economical capital of the State of Palestine, Nablus city is one of the largest cities in West bank. Al-Bathan village which locate to the east of Nablus city, it is a touristic region that is visited from peoples from all regions all the time. Identification of the Problem The main reason for choosing this project is the problem in the current Al-Bathan road which is the landslides in some of its sections. Not long time ago, a severe collapse in the land under the road had occurred which cause a complete ruin on a section of the road and make it very difficult for the road users to travel using this road, the road in its current situation is a real risk especially in night because the road is not lightened. Geological Point View for the Problem There are three main types of rocks, Igneous rocks, Metamorphic rocks, and Sedimentary rocks. Sedimentary is the predominant type of rocks in Palestine. Sedimentary rocks has several main groups, carbonate is one of the most common main groups since a large portion of these rocks has carbonate (CO3-2) in its chemical structure. Carbonate main group is mainly consisting of Calcite (CaCO3) and Dolomite ( Mg,Ca(CO3)2 ). Carbonate group has several types of rocks, such like Limestone, Chalk, and Marlstone. Limestone is considered as a good rock layer which can be used as a construction layer for buildings, streets, etc. Chalk is also considered as a stable rock layer. But the main problem of Carbonate group is Marlstone. Marlstone consists of Calcite ( CaCO3 ) and Clay minerals, the risk of Marlstone is because its high potential of swelling when it is exhibited to water. And the higher percent of clay minerals in Marlstone the higher the absorbed water, which means a higher risk.
