Abstract
Due to continued
growth and rapid development of road construction, identification and
recognition of type of soil and soil behaviour in different condition help us
to select soil according to specification and engineering characteristic, also
if necessary sometimes stabilize the soil and treat undesirable properties of
soils by adding materials such as bitumen, lime, cement and etc. If the soil under
pavement is not done according to the standards, construction will need more
cost and construction time. In this case, a large part of soil should be
removed, transported and sometimes deposited. Then purchased sand and gravel is
transported to the site and full depth filled and compacted. Stabilization by
cement or other treats gives an opportunity to use the existing soil as a base
material instead of removing it and purchasing and transporting stabilized
materials. In this study soil classification and the relation between soil
classification and stabilization method is discussed, cement stabilization with
different percentages have been selected for soil treatment based on National Cooperative Highway Research Program
(NCHRP). In this study California Bearing Ratio (CBR) will be used to define
the strength. Because for flexible pavements, the subgrade is considered an
ideal layer to withstand wheel load, and the CBR value is considered a force
measuring parameter. 0%, 3%, 7% and 10% cement
were added to different soil types to evaluate its effect on CBR values and
plasticity properties of treated soil. Results showed that cement addition
increased CBR values of different soil types by the rate of 22-69%.

Abstract
Yol yapımının sürekli
ve hızlı gelişmesi nedeniyle, farklı koşullarda toprak tipinin ve toprak
davranışının tanımlanması ve tanınması, şartnamelere ve mühendislik
özelliklerine göre toprağı seçmemize, gerektiğinde toprağı iyileştirmeye ve
toprakların istenmeyen özelliklerini işlemesine yardımcı olur. Yol kaplaması
altındaki toprak standartlara göre yapılmazsa, yapılaşma daha fazla maliyet ve
inşaat süresine ihtiyaç duyacaktır. Sağlam toprağın eksikliği bölgedeki toprağın
kaldırılmasını taşınmasını ve bazen de depolanmasını gerektirmektedir. Daha
sağlam dolgu malzemesinin sahaya taşınması ve arazide sıkıştırılması ek maliyet
gerektirmektedir. Çimento veya diğer mineral katkılarla zeminin iyileştirilmesi,
mevcut malzemenin yerinde kullanımı açısından destek sağlamaktadır. Bu
çalışmada, farklı toprak sınıflandırmasına göre Ulusal Kooperatif Karayolu
Araştırma Programına (NCHRP) dayanarak toprak işlemesi için farklı oranlarda
çimento stabilizasyonu seçilmiştir. Bu çalışmada, dayanımı tanımlamak için
Kaliforniya Taşıma Oranı (CBR) kullanılacaktır. Çünkü esnek yol yabakası için
gerekli olan alt katman, tekerlek yüküne dayanacak ideal bir katman ve CBR
değeri, bir kuvvet ölçüm parametresi olarak kabul edilir. Çimentonun toprağın
CBR değerleri ve plastisite özellikleri üzerindeki etkisini değerlendirmek için
farklı toprak türlerine % 0, % 3, % 7 ve % 10 çimento eklenmiştir. Sonuçlar
çimento ilavesinin farklı toprak tiplerinde CBR değerlerini % 22-69 oranında
arttırdığını göstermiştir.
