II. PAVEMENT ENGINEERING AND PAVING MATERIALS

1. SOIL STABILISATION, LOW GRADE MATERIALS AND LOW VOLUME ROADS

A. ON GOING PROJECTS
1. Use of Ash Generated from Surat Lignite Power Plant for Different Types of Clayey Soil for Construction of Roads
Date of Start:

May 2003
Gujarat Engineering Research Institute, Vadodara (R)

 

Present Status and Progress
Laboratory work with CI, CL and CH type of soil mixed with different proportions of lime and ash is completed and reporting work is under progress.
 
Findings/ Conclusions
It is an eco friendly material
Looking at the results of mixes of ash and lime with different types of clayey soils it is found that density decreases with addition of lime and ash but the CBR value increases as under.
