2022年11月8日 The aggregate crushing value test (ACV, BS 812-Part-110) is one of the test methods for determining the crushing resistance of the aggregates. Alvarado et al. [ 4] and Reyes et al. [ 5] concluded that the ACV test was practical, reproducible, and stable and is a pivotal method in the evaluation of aggregate crushing resistance.
2019年11月20日 The aggregate crushing value can present a relative resistance capability against crushing under compressive loads. Aggregates with lower crushing value are desirable for heavy-duty HMA pavements. The aggregate crushing test was conducted in accordance with the Chinese Standard Test Method of T3016-2005. 3000 g aggregates

2021年5月1日 The aggregate crushing value is an essential index in the construction of road bases and is defined as the mass percentage of fine particles after a confined compression test of recycled CDW.
2011年1月1日 The results obtained show that ACV value for aggregates are 25.04%, 22.70%, 36.13%,and 37.89% for crushed granite, slag,hoggin (all-in aggregate), and river gravel respectively. This show...
2019年3月11日 The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, 1.The material for the standard test shall consist of aggregate passing a 12.5 mm IS Sieve and retained on a 10 mm IS Sieve, and shall be
1990年6月29日 This Part of BS 812 describes a method for the determination of the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve.
The aggregate size fraction taken for this test can also be as per the relevant national standards. NOTE Minor variations in grading divisions can be allowed in respective national standards. The method is not suitable for testing aggregates with an aggregate crushing value higher than 30.
Annex A Recommended method for determining the ten per cent fines value for other size fractions of aggregate. A.1 General. A.2 Apparatus National standards can also exist for the aggregate size fraction to be taken for this test. This method gives a relative measure of the resistance of the aggregate crushing under the gradually
2021年5月1日 The testing procedure to determine the aggregate crushing value typically follows the testing standard BS 812–110: 1990 ( British Standards Institute, 1990 ). The tested aggregates are compacted and compressed in a cylinder by a
