II. PAVEMENT ENGINEERING AND PAVING MATERIALS

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

Summary
Use of waste materials and abundantly available surplus agricultural products are of significance in the present context. The road construction techniques need to consider these materials for improving the function of structure which also help in undue shortage of such materials. The techniques also need to address optimizing the proportion of such unconventional materials and the economic implications of the same.
SALIENT POINTS FOR DISCUSSION
1. Use of waste materials like coal ash and marble slurry in pavement layers
2. Effect of addition of other materials like lime
3. Suitability of different soils for above use
4. Ground stabilization of clay & silt with locally available materials like coir
5. Varied use of these materials in road construction
