Question

A New Zealand standard compaction test gave the following results. Assume p = 2.7t/m^3. Calculate the dry densities to complete the table. Plot the dry density against water content and the 0% air voids. From the graph find the maximum dry density, the optimum water content and the percentage of air voids at MDD What is the water content necessary for complete saturation at MDD.

Dry density (kg/L)	Water content (%)	Dry density (kg/L0	Dry density at 0 % air voids	Dry density at 5% air voids
1.866	9.4
2.019	11.5
2.112	13.5
2.136	15.1
2.105	17.1
2.065	19.1
