Efektivitas Injeksi Larutan Kapur untuk Menurunkan Plastisitas Tanah Lempung sebagai Upaya Mengatasi Kerusakan Jalan Raya
Abstract: Highway built on
high plasticity clay will be easily damaged by groundshrinkage flower essence.
Stabilization of clayby mixing lime is a repairement method that has been
proven quite effective. However, this method is difficult to be applied in
existing road because demolition must be
done. Stabilization of clay using lime solution injection is the method
proposed toovercome the problems of
expansive clay under the existing highway, therefore demolition is not required.
This study was conducted to obtain effective parameters influencing the distance
lime solution injection sites and time required for complete stabilization
process. This research was conductedin labotarorium by injection experiments.
Test results shows indications of soil plasticity decrease, especially the value of plasticity index (PI) and liquid
limit (LL). PI decreases from 24.74% to 19.5% and LL decrease from 52.32% to
45%. Based on data analysis it appears that the time required for complete lime
solution injection (effective time) has not been obtained in this test. Based on test data, until the day
28 value of soil plasticity index is still low. In this study obtained
effective distance influencing the injectionsolution of lime is 100 cm. The
distance is still need to be enlarged by increasing the high pressure.
