Effect Of Compaction Delay on Metakaolin Stabilized Lateritic Soil for Highway Construction
Abstract
The research investigate the effect of delay in compaction of soil stabilized with 10 percentage of metakaolin for highway construction. The physical properties tests on the natural soil classify the soil as A-2-7 soil according to Association of State Highway Transport Officials (AASHTO) and Well Graded Clay Sand GW according to Unified Soil Classification System (USCS) and mechanical tests was conducted on both natural and stabilized soil. However, the stabilized soil was delayed for 2, 4, 6, 8 and 10 hours to evaluate the influence of compaction delay on the treated soil samples. The compaction characteristics on the natural soil were 1.83 Mg/m3 and 9.6% for MDD and OMC respectively.The strength properties on the stabilized soil shows a declined as compaction delays increases. At 7-day UCS the maximum value for the BSH energy level was 747KN/m2, and the CBR was 43% un-soaked and 39% for Soaked CBR after a 2-hour delay. Since stabilization using 10% metakaolin and a compaction delay of more than 2 hours reduces the soil's strength, the impact of another stabilizing agent in addition to metakaolin can be examined further.
