Studding of Geotechnical & Economical Characteristics of Hezardare Conglomerate in Order to replacing with River Aggregates

 Abstract
      Aggregates are the most common and the cheapest materials for construction purposes. Nowadays; alluvial are the main resources for providing construction aggregates. However, the shortage of alluvial resources and also environmental consequences of alluvial excavating has drowned the attentions to producing aggregates from rock resources.
   In this paper, geotechnical properties of Hezardareh conglomerate have been investigated to replace it with alluvial resources. This investigation confirmed that those zones of Hezardareh formation which have not been affected by secondary sedimentation and the content of the harmful materials such as gypsum, salt, clay minerals and etc. are lower than alluvial limits, have suitable geotechnical properties in order to produce aggregate materials. Meanwhile, feasibility studies verify that the production of these resources is cost effective.
