|Title:||Comparison between static and dynamic compaction for California Bearing Ratio (CBR)||Authors:||Doris Asmani, M.Y.
|Issue Date:||2013||Abstract:||California Bearing Ratio (CBR) test is generally used to estimate the shear strength and stiffness modulus of subgrade in pavement design. Thus, a new laboratory compaction method has been created to obtain the CBR values based on OMC values by using Static Laboratory Compaction Method. Based on the laboratory results, it was found that the static compaction method is more practical and sensible than the dynamic compaction. Static compaction gives higher value in density of soil and CBR values. The static compaction onto Soil A specimen has given the value of MDD= 1.86 Mg/m3, and the CBR value was 22.62%. Whereas, the dynamic compaction applied onto Soil A specimen has given the value of MDD= 1.74 Mg/m3, and the CBR value was 20.14%. Furthermore, this method was created in order to close the gap between laboratory and field data in terms of developing further to improve engineering parameter especially for pavement design. According to the experimental results, the CBR values obtained from static compaction tests were higher than dynamic compaction method. In conclusion, this type of research is developed to improve engineering parameter, especially for road construction design and the higher CBR value can minimize the road design thickness and consequently reducing the cost of road construction. © 2013, EJGE.||URI:||http://dspace.uniten.edu.my/jspui/handle/123456789/9295|
