aggregate tests are illustrated and explained below Note: since 2004, the range of tests carried out on aggregates for construction purposes has been harmonised throughout the European Union Some familiar aggregate tests previously used in the UK and Ireland, such as Aggregate Crushing Value,...

2 Aggregate Crushing Value Aim: To calculate aggregate Crushing value by testing aggregate passing 125 mm sieve and retained on a 10 mm sieve Scope: This procedure covers all relative activity for the project site Apparatus: 15cm dia steel cylinder with plunger and base plate; Tamping rod 16 mm dia and 600 mm long with one end rounded...

Aug 27, 2019· Significant degradation may take place when the aggregate is weak Thus, an aggregate complying with a specification at the production site may fail to do so when it is in the pavement The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load...

Overview The Los Angeles (LA) abrasion test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA Figure 1: LA abrasion testing equipment...

Table 54 presents the statistical data of the LA abrasion mass loss, aggregate crushing value (ACV) and aggregate impact value (AIV) obtained from 307 RA sampl As expected, the LA abrasion results suggest that the resistance to fragmentation of RA, in descending order, is RCA, MRA and RMA However, this trend is not clear in the case of AIV and ACV...
