Effect calcium hydroxide (traditionally called slaked lime) to stabilization of laterite soil

Inadequate road infrastructure conditions make the airway a mainstay for the
transportation of people and goods, including basic needs in several Papua areas. This study
aims to determine the value of elastic modulus and poison ratio that has been stabilized with
hydrated lime using curing water and air for 7 days. The method used in this research is
experimental method in laboratory. The test object dimension used is cylinder 53 x 106 mm.
The soil samples used in this soil stabilization study were taken from Tanah Merah Bovendigul
District. Clay and lime soil mixtures are prepared by using moisture content of 35%. The
results test shows that the average value of elastic modulus (vertical and horizontal) on curing
of water and air is 122.82 MPa each; 92.23 MPa and 51.11 MPa; 424,43 MPa. While the
average value of poison ratio is respectively of 0.2 and 0.1.
