Hoʻolālā ʻia nā mea kanu asphalt mana no ka hana ʻana i nā pōhaku mastic asphalt a loaʻa iā mākou kahi module i loko o kā mākou ʻōnaehana polokalamu. Hoʻopuka pū mākou i ka cellulose dosing unit.Me kā mākou limahana akamai, hāʻawi mākou ʻaʻole kūʻai mea kanu wale nō, akā ke kākoʻo hana ma hope o ke kūʻai aku a me ka hoʻomaʻamaʻa limahana.

ʻO SMA kahi ʻāpana lahilahi (12.5–40 mm) i hoʻopaʻa ʻia, HMA i hoʻohana ʻia ma ke ʻano he papa honua ma ke kūkulu hou ʻana a me ka hana hou ʻana o ka ʻili. He hui ia o ka asphalt cement, coarse aggregate, crushed sand, and additives. He ʻokoʻa kēia mau hui ʻana mai ka hui ʻana o ka HMA mānoanoa maʻamau no ka mea he ʻoi aku ka ʻoi aku o ka nui o ka hui ʻana i loko o ka hui SMA. Hiki ke hoʻohana ʻia ma nā ala nui me ka nui o nā kaʻa. Hāʻawi kēia huahana i kahi papa ʻaʻahu kūʻokoʻa a kūʻē i ka hana abrasive o nā kaʻa studded. Hāʻawi kēia palapala noi i ka ʻelemakule lohi a me ka hana haʻahaʻa haʻahaʻa maikaʻi.

Hoʻohana ʻia ʻo SMA no ka hoʻonui ʻana i ka pilina a me ka hoʻopili ʻana ma waena o ka hakina hōʻuluʻulu nui ma HMA. Hāʻawi nā ʻāpana sima asphalt a me nā ʻāpana hui ʻoi aku ka mastic e paʻa ai ka pōhaku i kahi pili pili. He 6.0–7.0% ka 6.0–7.0% me ke ano o ke ano o ke ano he 6.0–7.0% me ke ano o ke ano o ka lua (a i ole ka polymer-modified AC), 8–13% filler, 70% oi aku mamua o 2 mm (No 10) sieve, a me 0.3–1.5% na fiber e. kaumaha o ka huikau. Hoʻohana mau ʻia nā fibers e hoʻopaʻa i ka mastic a hoʻemi kēia i ka hoʻokahe ʻana o ka mea hoʻopili i loko o ka hui. E mālama mau ʻia nā voids ma waena o 3% a me 4%. Mai ka 5 a hiki i ka 20 mm (0.2 a hiki i ka 0.8 in.) ka nui o ka nui o nā ʻāpana.

ʻO ka hui ʻana, ka lawe ʻana, a me ka hoʻokomo ʻana o SMA e hoʻohana i nā mea hana maʻamau a me nā hana me kekahi mau ʻokoʻa. No ka laʻana, ʻoi aku ke kiʻekiʻe o ka hui ʻana ma kahi o 175°C (347°F) pono ma muli o ka coarser aggregate, additives, a me ka asphalt viscosity kiʻekiʻe i nā hui SMA. Eia kekahi, i ka wā e hoʻohana ʻia ai nā fiber cellulose, pono e hoʻonui ʻia ka manawa hui e hiki ai ke hui pono. Hoʻomaka koke ka ʻōwili ʻana ma hope o ke kau ʻana e loaʻa koke ka paʻa ma mua o ka emi nui ʻana o ka wela hui. Hoʻokō pinepine ʻia ka hoʻopaʻa ʻana ma o ka hoʻohana ʻana i nā wili huila kila he 9-11 tone (10-12 ton). Hiki ke hoʻohana ʻia ka ʻōwili vibratory me ka akahele. Ke hoʻohālikelike ʻia me ka HMA mānoanoa dense-graded, ʻoi aku ka maikaʻi o ka pale ʻana i ka shear, abrasion, abrasion resistance, cracking resistance, a me ka skid resistance, a ua like ia no ka hana leo. Hōʻike ka papa 10.7 i ka hoʻohālikelike ʻana o ka gratation o SMA i hoʻohana ʻia ma ʻAmelika Hui Pū ʻIa a me ʻEulopa.
