b.Ballast
c.Flooring, paving and stair trades
d.Wall and floor surfaces
e.Window sills
f.Concrete aggregate
3.Discuss principles behind the use of seismic refraction and electrical resistivity methods in site investigation. What is the difference between resistivity profiling and Vertical electrical sounding? 4.How many parameters has been used in obtaining Q rating of rock masses. Explain each of the parameters and how would they affect the rock mass strength. Briefly explain how Q classification differs from rock mass rating (RMR) classification of rock masses? 5.What methods and materials could be used in monitoring and mitigating landslips/landslides.
