Utilization of Industrial By-Products are Tested for Use on Highways

by Behlül Kula | Dec 01, 2021
In today's world, beneficial reuse of industrial by-products in civil engineering applications is of significant importance. For our developing country, highway constructions are a valuable one of those applications. In particular, use of industrial by-products in highway drainage systems as an alternative material for natural aggregate is a popular research topic. In this study, industrial byproducts with different physical and chemical characteristics have been subjected to an extensive laboratory testing program to determine the physical impacts when used in highway drainage systems for filtration purposes.

Project Title: Utilization of industrial by-products in highway drainage systems : An experımental study
Project Type: İTÜ BAP - Genel Araştırma Projesi

Abstract:  In today's world, beneficial reuse of industrial by-products in civil engineering applications is of significant importance. For our developing country, highway constructions are a valuable one of those applications. In particular, use of industrial by-products in highway drainage systems as an alternative material for natural aggregate is a popular research topic. In this study, industrial byproducts with different physical and chemical characteristics have been subjected to an extensive laboratory testing program to determine the physical impacts when used in highway drainage systems for filtration purposes. In order to investigate primarily the clogging mechanism when used for filtration, long term filtration tests have been conducted to evaluate the clogging behavior of the drainage system consisting of the aggregate/industrial byproduct and geotextile. The experiment system described in ASTM D 5101 has been slightly modified and the new system was manufactured accordingly. The gradient ratio (GR) and the permeability ratio (KR) , the two parameters defining the clogging performance of an aggregate/geotextile system have been determined under various hydraulic gradients. Furthermore, the effect of material type on clogging mechanism was physically investigated and the results were discussed.

It can be accepted that the history of ITU Civil Engineering Faculty was commenced in 1727 by the establishment of Humbarahane during the era of Damat İbrahim Paşa. However, this attempt was to no avail due to the martyrization of the studwents of this school by the Janissaries.


In 1734, during the grand viziership of Topal Osman Paşa, classes related to Civil Engineering was being taught in Hendesehane, which was founded in Üsküdar. Similarly, this school was also closed after three years due to the opposition of the Janissaries. The reasons of the tragedy that occured in Battle of Chesma, 1770 were inadequacy of the ships and the ignorance of the Ottoman Navy.


Although the Atlantic Map (1513) and the Map of Europe and the Mediterranean Sea (1523) by Piri Reis were the leading pieces of the era, Ottoman viziers were so ignorant that they claimed it was impossible for the Russian Baltic Fleet to reach the Mediterranean Sea assuming that there were no sea connection. With the proposal from Gazi Hasan Paşa and Baron de Tott, Mühendishane-i Bahri-i Humayun was established during the time of Sultan Mustafa III, aiming to train naval construction engineers. Since Ottoman Empire did not have any engineering schools at the time, military engineering classes were taught by French engineers beginning from 1784. French lecturers had to return to their country in 1788 with the increasing suppression from Austria and Russia, which were unwilling for the development and thriving of Ottoman Empire. In 1759, during the Grand Viziership of Koca Ragıp Paşa, Humbarahane was reopened in Karaağaç, Haliç (Golden Horn) and continued to teach even though it was incompetent. In 1792, Lağımcı Ocağı and Humbaracı Ocağı (Guild of Sappers) were established.
