About this app

The required inputs for the calculations are laboratory test results of the road construction materials. The road construction materials that are to be tested in a laboratory are subgrade soil, embankment fill gravel soils, capping layer gravel soils, sub base course gravel soils and base course granular materials. The required tests are carried out by internationally accepted testing methods such as AASHTO, ASTM, BSI, etc.
All test calculator app performs calculations of liquid limit (LL), plastic limit (PL), plasticity index (PI), California bearing ratio (CBR) and Swell values at 2.54mm and 5.08mm penetrations; group index (GI) calculation and performs soil classifications.
Based on the calculations and material classifications, the Civil (Material) Engineer can conclude that the tested material can be used or not for the required purposes. Therefore, this app is very useful for the road construction engineers.
