ABSTRACT: It i wll known that paking nity aggrgat, whih i rlat to itribution aggrgat, aggrgat iz, hap, urfa txtur, play an important rol in prforman onrt. All xiting mauring th paking nity aggrgat ar arri out unr ry onition. A nw, whih maur th paking nity aggrgat unr wt onition, ha bn vlop. It i all th wt paking. Partil paking mol, whih ar u to timat th paking nity/voi ratio th oli ombination, an provi tool to improv th prforman onrt. In thi papr, paking nity aggrgat in variou onition inluing ry wt paking wr xprimntally alulat. Finally, alulat rult unr wt onition hav bn ompar to tho unr ry on hav bn vrifi by thortial mol. INSTRUCTION Paking nity, fin a th volum oli pr total bulk volum, whih i wily u to valuat ombin aggrgat. Th gomtrial haratriti hap, angularity, txtur, partil iz itribution afft paking nity; thrfor, paking nity an b u a an inirt iniator aggrgat gomtrial haratriti. In gnral, highr paking nity i prfrr, although th maximum paking nity may not b optimal (ohann & Anrn 99, Goltrmann t al. 997, Powr 93, Powr 968). Aoring to (Goltrmann t al. 997) onrt mix houl hav mor fin aggrgat than what i rquir for th maximum paking nity. Howvr, it houl b not that a mall hang in ontnt o not gnrally au a larg hang in paking nity. Mol for paking nity hav bn appli for Slf Compating Conrt (SCC). SCC with nar optimum aggrgat paking xhibit lowr vioity, lowr High-Rang Watr-Ruing Amixtur (HRWRA) m, imilar or gratr filling apaity than SCC with lightly lowr aggrgat paking nity (Khayat & Lay ). Vahon, t al. utiliz th ompribl paking mol to lt aggrgat for SCC (Vahon t al. ). Rarhr hav publih om mathmatial mol to prit paking nity powr partil (Stovall t al. 988, Yu & Stih 988, Yu t al. 997, Suzuki t al., Raouly 999). Stui on paking rhologial bhavior hav bn prform for no-lump onrt/ Rollr Compating Conrt (Oullt 997, Lahu ), for SCC (Noguhi t al. 999) for Ultra High Prforman Conrt (Nhi & Min 998, Ginhanlu & Shmit 4, aobn t al. 5) iniating varying mpirial rlation. Rgaring th paking nity maurmnt, th onvntional, a tipulat in th xiting tar, uh a (Blgian Star NBN B-6 (98), Britih Star BS 8: Part (995), Europan Star EN 97-3 (998) EN 97-4 (999)), maur th bulk nity th oli partil unr ry onition trmin th paking nity a th ratio th bulk nity to th oli nity. Th, hraftr all th ry paking, ar wily u. For intan, (DShuttr & Popp 4) hav maur th paking nity a pr th Blgian Star orrlat th paking nity o trmin with th watr m th in mortar. Howvr, In pit th goo orrlation obtain by thm, it i, in fat, not appropriat to maur th paking nity uing any ry paking (Fung t al. 8).

2 . Thortial mol Paking mol, whih ar u to timat th paking nity th aggrgat, hav bn vlop ovr th pat 7 yar. Th Furna mol (Goltrmann t al. 997) onir th ial paking phrial partil to obtain th maximum nity a binary ytm. In a mixtur two kin partil, (iamtr <<, volum fration r r, paking nity ), thr ar two limiting a: ) r >>r ) r << r. In a th paking nity th mixtur i: = () r + r In a th paking nity th mixtur i: = r () Th Furna mol i only vali for a binary ytm at whih <<. Toufar mol (Toufar t al. 976) alulat th paking nity a multi-omponnt mixtur (mor than la). Th bai onpt th mol i that th iamtr ratio mallr partil/largr partil i largr than., th mallr partil i too larg to b ituat within th intrti btwn th largr partil th mixtur form om pak ara oniting mainly mallr partil.
