DETERMINATION OF AGGREGATE CRUSHING VALUE aggregate to crushing under a gradually applied compressive load Crushing value is a measure of the strength of the aggregate The aggregates should therefore have minimum crushing value 3 APPARATUS The apparatus of the aggregate crushing value SECTION 406 ASPHALTIC CONCRETE 4061 Descriptionrequirement for aggregate crushing value for asphaltic concrete If you want to learn about our products , please call or write mail consultation To determine the technical requirements of crushing value of coarse aggregate used in pa mixture, steploading compression tests were conducted on the mixtures of pa and a control asphalt free requirement for aggregate crushing value for Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, steploading compression tests were conducted on the mixtures of PA13 and a control asphalt mixture AC13, respectivelyStandard of Crushing Value of Coarse Aggregates for Aggregates for Asphalt Concrete The amount of aggregates for asphalt concrete mixtures is generally 90 to 95 percent by weight and 75 to 85 percent by volume Aggregates are primarily responsible for the load supporting capacity of a pavement Aggregate has been defined as any inert mineral material used for mixing in graduated particles or HOW TO EVALUATE QUALITY OF AGGREGATES FOR 4 When tested in accordance with AS 114142 aggregate shall be rejected if the Polishing Aggregate Friction Value (PAFV) for the aggregate is less than 44 Polishing Value (b) Fine Aggregate 1 Fine aggregate comprises all mineral matter (other than filler) passing the 475 mm AS sieveASPHALTIC CONCRETE Mackay Council
