The cone crusher (a compression type) simply crushes the aggregate between the oscillating cone and the crusher wa ll (Figure 5-9). Clearance settings on this equipment are required to be checked and maintained as part of standard operating procedure. Figure 5-9. Cone Crusher
The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load. The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions (Figure 1). Dry aggregates passing through 12.5 mm sieves and retained 10 mm sieves are filled ...
· Los Angeles''s abrasion test on aggregates is a measure of aggregate toughness and abrasion resistance such as crushing, corrosion and disintegration. Aggregate abrasion characteristics are important because the component aggregates in HMA (Hot Mix Asphalt) must resist crushing, degradation, and disintegration to produce high quality HMA.
1) To determine the aggregate crushing value of coarse aggregates 2) To assess suitability of aggregates for use in different types of road pavement 2. PRINCIPLE The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a
· Six aggregates sampled from different sources were subjected to various aggregate tests, including the Los Angeles abrasion, micro-Deval, soundness magnesium, and acid insoluble tests. A Superpave mix with a 12.5-mm (1/2-in.) nominal maximum aggregate size gradation was produced with each aggregate source using the same PG 64-22 asphalt binder.
