The mass of a bitumen dose [q.sub.B] (kg), ensuring the optimal amount of bitumen in percent [x.sub.Bp] in a HMA mixture which is specified in JMF, also depends on the actual mass [Q.sub.ma], of HMA mineral aggregates
and is calculated by the equation:
where [P.sub.b]--the approximate total bitumen demand of recycled mixture, percent by weight of mixture; [P.sub.CA]--the percent of mineral aggregate
retained on 2.36 mm sieve (coarse aggregate); [P.sub.FA]--the percent of mineral aggregate
passing the 2.36 mm sieve and retained the 75 [micro]m (0.075 mm) sieve (fine aggregate); [P.sub.MF]--the percent of mineral aggregate
passing 75 [micro]m sieve (mineral filler); K--the 0.15 for 11-15% passing 75 [micro]m sieve, 0.18 for 6-10% passing 75 [micro]m sieve, 0.20 for 5% or less passing 75 [micro]m sieve; F--the 0-2.0%, based on absorption of light or heavy aggregate.
However, malleable iron aggregate has an abrasion resistance entirely TABULAR DATA OMITTED TABULAR DATA OMITTED different than mineral aggregates
. Iron aggregates, although relatively soft, exhibit about 400 percent greater resistance to abrasion than mineral aggregates
