Abstract

The objective of this research is to study properties of Laterite, Ferro slag and Laterite mixed with Ferro slag in various mixed ratio that be compared in accordance with Highway Engineering Standard. Materials were tested to determine California Bearing Ratio (CBR), the relationship of Soaked CBR and Unsoaked CBR and mixed ratio that be appropriated to use for Base Course in Highway Engineering work.The results shown that Ferro slag can increase Laterite's bearing capacity and improve the physical properties that necessary for work in restricted condition, we can used Ferro slag to make the lofty benefit in steel industrial and be worth for environment so we can said that Ferro slag good for replace Laterite in Highway work. Refer to Highway Engineering Standard for Base course that said the appropriated CBR for Base Course work is 80%, the optimized mixed ratio for soaked CBR at 7 days is 60.00%, for soaked CBR at 14 days is 72.20% and for soaked CBR at 28 days is 89.20%. For unsoaked CBR , the optimized mixed ratio at


 


curing time 0 day is 50.00%, at curing time 7 days is 44.80%, at curing time 14 days is 39.70% and at curring time 28 days is 34.20%.
