  • Aggregate Impact Value Test | Impact Test Of Aggregate | Impact Value

    The impact test on aggregate is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life. The need for impact value test is used to measure the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or impact loading.

  • How to determine Soil Bearing Capacity from SPT Value

    SPT value can determined by counting the number of blow required to penetrate the last 12in (300 mm approx.) of a 18 in. ( 450 mm approx.) sampler. After getting this value we can easily determine the bearing capacity of soil by following formulas: Meyerhof''s Formula: For footing width 4 feet or less: Qa= (N/4) / K.
