1. Kutentha kwa zero, mtengo wamafuta
Zachikhalidwe Hma amafunikira kutentha mpaka 280-50 ° F, kudyetsa mafuta ambiri komanso zida zamagetsi zapadera ngati matogi otentha. Asphals ozizira amachotsa ndalamazi kwathunthu, kumenyedwa 1520% kuchokera ku bajeti pogwira ntchito kutentha.
2. Kukonza mwachangu, ntchito zochepa
Zoyenda zazing'ono kapena kugwiritsa ntchito kwa DIY: Asphalt osazizira safuna kugwira ntchito mwaluso, kuchepetsa kukula kwa ogwira ntchito ndi 30-50%.
Okonzeka kwambiri mu mphindi: Kukonzanso nthawi yayitali kuposa HMA, kudula maola ogwira ntchito mwachangu kwambiri pofika $ 1,000.
3. Kuchita bwino kwa nyengo = palibe chosowa
Mapulojekiti a Hma amayendetsa mvula, chipale chofewa, kapena kuzizira. Phula laukali lozizira lili ndi vuto lililonse, kupewa kuchepa kwa ndalama zokhudzana ndi nyengo ndi mgwirizano. Maulamuliro a Statilows a Refert 30% ochepera oyimitsidwa pachaka mukamagwiritsa ntchito chigamba chozizira.
4. Kusunga Magalimoto
Ndi HMA, kuyandikira kwa msewu atha maola omaliza. Kuphatikiza kwa masfals asphalt's nthawi yomweyo kumapereka misewu kuti athetsenso nthawi yomweyo, kuchepetsa ndalama zowongolera zamagalimoto (chizindikiro, Crew nthawi yayitali) pofika 60%.
5. Zoyeretsa zakuthupi
Zobwezeretsedwanso: Zambiri za phula zambiri zophatikizika zimaphatikizidwa asphalt (rap) kapena tayala la tayala, ndalama zotsika mtengo ndi 10-15%.
Zinyalala zochepetsedwa: Kukonzekera koyenera kumachepetsa zinthu zochulukirapo. Palibe ma batisi omwe adakanidwa chifukwa cha kutentha.
Ubwino wa 40% wofotokozedwa
Kusunga kosazizira kwa shephals kuchokera kuphwero kuchokera kuphweka: Palibe kutentha, palibe makina olemera, osaletsa nyengo, ndikubwezeretsanso zinthu. Pomwe HMA imawononga 40-80 / toni, ozizira patch (90-130 /)
