This research was conducted in the laboratory, by testing the physical properties of soil and the strong support of land (CBR) with the addition of lime variation of 1%, 3%, and 5% by long curing 0, 4, 7 and 14 days. Tests were conducted with two treatments, soil samples were cured first and then compacted and samples were pressed first and brooded. The result is the value of CBR. %. From the results of the value of the California Bearing Ratio can be seen that the addition of sand quarsa on soil clays showed an increase in the value of the California Bearing Ratio in soil clays.","PeriodicalId":200000,"journal":{"name":"JOURNAL OF CIVIL ENGINEERING, BUILDING AND TRANSPORTATION","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114122879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The large decrease is due to the decrease in soil. The condition of poor base soil in the form of clay soil needs to be done to improve the basic soil to be able to support the construction load. One method used as land improvement is by geotextiles. The type of geotextile used in the construction of the Medan-Kualanamu-Tebing Tinggi toll road project, Parbarakan-Lubuk Pakam Sta.42 + 750-Sta.47 + 600 is a geotextile PP woven polypropylene. The geotextile type uses non woven geotextile while the study is geotextile polypropylene woven, Non woven tensile strength 20 kN / m required 1 layer of geotextile while tensile strength Polypropylene woven 30 kN / m required 2 layers of geotextile.
