Crushed coarse aggregate shall not have more than 50 percent wear at 500 revolutions as determined by ASTM C 131. When the fraction of the aggregates retained on the No. 4 mesh (4.75 mm) sieve is subjected to five cycles of the sodium sulfate soundness test (ASTM C 88), the

The same apparatus is used for the coarse aggregate test method that is used for the fine aggregate test method. Sample Preparation Subject the sample to be tested to AASHTO T 11, Amount of Material Finer Than No. 200 (75 µm) Sieve. The aggregate sample shall be dried to a constant weight at a temperature of 230° ± 9°F (110° ± 5°C).

In Tab. 1 and 2, to perform a comparison with the coarse aggregate recycled by pulsed discharge as discussed later, we show the results of a screening test, a density test and a water absorption test for the two types of test specimens of commercially available material: recycled coarse aggregate of relatively high quality (Figure 1. recycled ...

Coarse Aggregate Test. Durability of coarse aggregate is normally evaluated in the sulfate soundness test and water absorption tests, and by measuring resistance to impact in the Los Angeles abrasion and impact test. The likely performance of aggregates in granular base is best measured by the micro-Deval test and water absorption.

The coarse aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a coarse aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the fine aggregate specific gravity test.
