PAVEMENT ENGINEERING AND PAVING MATERIALS
1.SOIL STABILISATION, LOW GRADE MATERIALS AND LOW VOLUME ROADS
SUMMARY

In this sub-section, nine projects comprising of six new projects, two ongoing projects and one completed project have been reported. A completed project on soil stabilization for pavement sub base construction has been reported. Under this project laboratory studies have been conducted to improve CBR value of soils. The project on use of fly ash for construction of roads, waste and recycled information database used in highway/geotechnical-related applications have been discussed. The study and measures of road construction in presence of harmful salts in UP and study of reconstruction of rural roads in place of renewal work have been reported.

SALIENT POINTS FOR DISCUSSION
1. Soil stabilization for pavement sub base construction
2. Measures of road construction in presence of harmful salts
3. Use of fly ash for stabilization different types of clayey soil for road construction.
