Asphalt mixture of limestone or slag must adopt strong magmatic rocks mafic rocks hydrophobic aggregates obtained by ground slag, clay impurities in the original stone should be Ex . When using fly ash as filler , the amount shall not exceed 50% of the total filler , LOI should be less than 12% fly ash , slag mixed with the plasticity index should be less than 4%, but the highway , a asphalt surface roads should not be used to make fly ash filler .
Fly commonly used as an ash fineness fineness: refers to 45μm square mesh sieve margin of not more than 12% , which is the powder industry was often said 45μm by 88% (45μm equivalent to 325 mesh ) . Two ash fineness: 45μm square hole sieve margin requirement is not more than 25%. Three fly ash fineness: 45μm square hole sieve margin requirement is not more than 45%. For fine - original fly ash , the - original fly ash and coarse - original fly ash mortar , due to the use of fine - surface area greater than the original fly ash , ash has greater activity, mortar specimens various age compressive strength does not meet or exceed the strength of the fly ash mortar specimen.
From the above , we understand the importance of slag and fly ash powder and asphalt concrete mix in , so for the preparation of slag and powder , etc. also need to attach great importance to choose ore milling machine for asphalt concrete needs of requirements for optional filler , VIPEAK Heavy series with new mill Raymond mill , for example, it can be processed ore 80-325 mesh fineness between asphalt concrete mix is more reasonable to procure asphalt concrete realize the value of their performance in the highway construction.
