Dab tsi yog Aashto Thermoplastic txoj kev cim xim thiab cov ntsuas qhov ntsuas
Aashtod Thermoplastic txoj kev cim cov xim yog cov khoom siv kub, cov txheej txheem ruaj, dav siv rau cov kev tsheb khiav ntau, tshav dav hlau, thiab qib sib deev, thiab chaw dav dav. Kev tsim hluav taws xob hluavtaws (E.G., C5 roj av rabin), rau cov khoom siv dawb, thiab cov khoom noj dawb paug), nws yog rhuab rau ntawm 1-3 feeb raws li txias. Cov ntsiab lus tseem ceeb muaj lub neej pabcuam ntev (2-5 xyoos), muaj kev tawm tsam siab, UV kis, thiab huab cua phem
Qhov ntsuas tseem ceeb ntsuas rau ib tus qauv Aashto:
Softening taw tes: 90-125 ° C (kom ua kom kub tsis kam tsis muaj deformation)
Retroreflectivity: 200-400 MCD / M² / lx (ntsuas nrog iav hlaws kom tau lees tias hmo ntuj pom kev)
Hla kev tiv thaiv: ≥45 BPN (tiv thaiv plam, kuaj ntawm British pendulum)
Compressive lub zog: ≥12 mpa (siv tau ruaj khov nyob rau hauv tsheb thauj khoom)
Luminance Factor: ≥0.70 rau dawb, ≥0.40 rau daj (tswj cov xim txawv thiab nruab hnub ua kom pom kev)
Kev ua raws ib puag ncig: Tsawg voc cov ntsiab lus thiab hnyav-hlau-qauv tsim qauv ua kom tau raws li kev cai lij choj eco-kev nyab xeeb
Cov Ntawv Ntxiv Ntxiv Npog Npog Cov Lus Qhia Cov Khaub Ncaws iav (18-30%), Kho Kom Muaj Zog, UV Cov Txheej Txheem Ua Raws Li Aashtic M249 thiab Allied Cov Qauv Zoo li ASTM D713
