       Notes - general: The existing method for determining the polished-stone
                        value (PSV) of an aggregate requires the use of
                        particles passing the 10mm test sieve and retained on
                        the 14 mm to 10mm flake sorting sieve.  In order to
                        determine the PSV of a number of samples of 20mm
                        uncoated and pre-coated chippings which are too large
                        to prepare standard test specimens, test specimens
                        made up by breaking aggrigate particules in half to
                        expose new faces were tested using the otherwise
                        standard procedure.  The results of these tests are
                        discussed and compared to the standard PSV value.
