WORKING STRESS DESIGN: Stress condition of structural member under working load
is given attention. Full strength of material is not utilizd and is reduced by
a factor. Stresses calculated are within the elastic limit. Is less economical
than USD. USD- ULTIMATE STRESS DESIGN: Focuses on the strength capacity of the
members at conditions corresponds to failure. Material properties are assessed
and used in design. Loads are multiplied by a factor. More economical
Cement's initial setting time should be 30 min(Minimum) and 90 min(maximum). Final setting time of cement should be=10 hours What type of test should perform for a road's improved subgrade sand filling: 1.FM of fine aggregates 2.California bearing ratio 3.Dynamic cone penetration test 4.MDD of fine aggregate 5.Field Dry Density.
