| Abstract | A study has been made of the aggregate impact test in relation
to the Los Angeles, aggregate crushing tests, water absorption, and specific gravities for samples of a number of aggregates in Thailand.
Samples were chosen to give information on: (a) the variation within one quarry (andesite); (b) limestones of different strengths; and (c) a range of different rock types. It was found that the results of the aggregate impact test could be used to predict the other test results. Due to the portability of the impact test apparatus and the ease of carrying out the test, it is suggested that this test
method would be useful in this area. For aggregates taken from the same quarry and probably having substantially the same mineral composition, there was very good correlation between the aggregate impact value and the bulk specific gravity. For weak aggregates, the modified aggregate impact test gave a wide range of values for aggregates of different strengths. The study of samples of andesite from Saraburi showed that some of the more weathered materials had increased water absorption
values. These differences could be detected by the aggregate impact test. The bitumen absorption of the weathered aggregate was higher than that of unweathered aggregate and this could account for .some
of the reported difficulties in using aggregates from this quarry. |
