<p><b>New page</b></p><div>This method determines the particle size distribution of fine and coarse aggregates extracted from bituminous mixtures, using sieves with square openings.<br />
<br />
==106.3.2.50.1 Apparatus==<br />
<br />
The apparatus required is specified in Section 4 of AASHTO T30. In addition, microwave ovens and hot plates with adjustable heating rates may be used as required.<br />
<br />
==106.3.2.50.2 Procedure==<br />
<br />
The procedure for determining the mechanical analysis of extracted aggregate shall be as specified in AASHTO T30 together with the additional requirements and modifications contained herein.<br />
<br />
The washed aggregate shall be dried to constant weight by oven, microwave oven or hot plate, with one exception: when steel slag is present in the aggregate, a hot plate is to be used to dry the aggregate to constant weight.<br />
<br />
Samples may be dried at temperatures higher than 110°C +5°C (230°F +9°F) provided steam escapes without generating pressures sufficient to fracture the particles and temperatures are not so great as to cause chemical breakdown of the aggregate.<br />
<br />
==106.3.2.50.3 Report==<br />
<br />
The results of the sieve analysis shall be reported to one decimal place, except, if a top size sieve is specified as percent passing that part of the gradation is to be rounded and reported to the nearest whole number.<br />
