To quickly assess the difficulty of the text, read a short excerpt:
Of the tests used to characterize particle shape, Huang bas developed a Particle on Index Test as a ineasure of shape, angularity and surface texture of aggregate particles [10] . These geometric characteristics of fractured rock may then be related to ballast cumulative deforsiation and responsiveness to maintenance tamping. In testing the resilient modulus of various ballasts at different gradations, Thompson has shown 132 Bulletin 704 — American Railway Engineering Association -that the part...icle index and resilient modulus test results appear to l>e related, although the relationship ±b inconsistent in:. The repeatability of the shape factor test is quest ioneOsle, since this test requires mezisurenent of "the largest dimension divided by the smallest." Although a measurement of this kind seems to be straightforward, there is a source of much variability between technicizms, since the ballast particles do not have well defined geometric shapes. The Particle Index Test Is fairly repeatable, however, emd gives a measure based on a number of particles acting together, rather than single particles aeasvired one by one manually.
