Abstract—Soil is the foundation of structure or construction that will receive the load transfer through to foundation. If the soil has a carrying capacity of small and cannot withstand the load transfer can result in the failure of construction. If the soil has a carrying capacity of small ground it is necessary to stabilize or improve the soil so that an increase in the carrying capacity of the land so that it can be used for construction. One material is commonly used for soil stabilization with the addition of lime. Waste chicken egg shell is waste that is still rarely used, the results of research is states that composition egg shell broadly consists of water (1,6%) and dry material (98,4%). The total dry ingredients are there, in shell eggs contained mineral elements (95,1%) and protein (3,3%). Based on the existing mineral composition, then the egg shells are composed of crystalline CaCO3 (98,43%), MgCO3 (0,84%) and Ca3(PO4)2 (0,75%). This research was done by adding powdered chicken egg shell waste in clay with a composition of 5%, 7,5%, 10% and 14% with physical properties test and soil compaction test. This research is an experimental study dan the results showed classification of soil with system USCS (Unified Soil Classification System) shows the percentage of grains of soil sieve No. 200 amounted to 60,24% (> 50%), then USCS ground based system can be classified as fine-grained soil, liquid limit is 31,92% and plasticity index is 5,44 so that the soil is classified as silt organic and clay organic with low plasticity (OL). Unit weight dry (dry) value in the addition of 10% waste chicken egg shell has increased a maximum of 1.58 gr/cm3 into 1,630 gr/cm3 at 14 days of aging (increase occurred at 3,164%). Water Content Optimun (wopt) in the addition of 10% waste chicken egg shell has decreased a maximum of 22,18% into 20,33% at 21 days of aging (decrease occurred at 1,85%).
