Vim li cas thiaj txias asphalt tau dhau los ua kev xaiv mus rau kev xaiv hauv kev
Kev kho cov neeg ua haujlwm pab pawg thiab cov chaw nyob hauv kev tso siab rau cov khaub thuas asphalt (lossis thaj txias) rau kev ua tau zoo, kav ntev. Ntawm no yog vim li cas cov khoom no ua thawj cov kev kho tshiab cov tswv yim:
Unmatching yooj yim & ceev:
Cov khoom noj txias asphalt tsis muaj tsis muaj cua sov, khoom siv tshwj xeeb, lossis kev ua haujlwm ntev. Nws tau ntim khoom siv-siv-siv, tso cai rau cov neeg ua haujlwm los sau cov potholes sai sai-txawm tias los nag, daus, lossis khov txias. Kev kho cov feeb, tsis yog teev, txo cov tsheb sib tsoo.
Daim ntawv thov huab cua:
Tsis zoo li ib txwm muaj kev sib xyaw ua ke hot asphalt (HGA) Nws cov polymer-hloov kho kom ntseeg tau cov nplaum ntawm cov chaw ntub dej thiab hloov tau thaum lub sijhawm khov-thaw mus.
Nqi-txiaj ntsig:
Though priced higher per ton than HMA, cold asphalt slashes overall costs by eliminating fuel, heating equipment, and large crews. Nws cov DIY-phooj ywg Xwm kuj tseem txo cov nuj nqis ua haujlwm rau kev kho me me.
Eco-tus phooj ywg Ntug:
Cov khaub thuas asphalt ntau lawm emits tsawg dua tsev cog khoom roj (feem ntau koom nrog cov khoom siv asplaimed asphalt pav ca cov (rap) lossis roj roj roj. Qhov no txhawb cov hom phiaj sustainability tsis muaj kev txi ua tau zoo.
Tam sim no Tsheb Npaj Tos:
Thaum tau cog tseg, cov kab mob txias Asphalt asphalt yog drivable hauv feeb. Qhov no "kev npaj cov kev npaj" yog qhov tseem ceeb rau kev muaj kev sib raug zoo, kho thaum muaj xwm txheej ceev, thiab cov chaw hauv nroog kom raug kaw.
Hauv qab kab:
Txias aspphalt 's sib tov ntawm kev nrawm, huab cua kuj, thiab cov nqi txuag tau ua rau nws pragmatic xaiv rau niaj hnub kev txij nkawm. Thaum HMA yog qhov zoo tagnrho rau cov nplai loj, cov khaub ncaws txias zoo nyob rau hauv cov lus teb sai sai - ua pov thawj tias kev ua tau zoo thiab durability tuaj yeem ua ke hauv kev tsim kho vaj tse.
