Chirimwa cheAsphalt Chinotakurika Chinogona Kuderedza Mitengo Yenyu Yekugadzira Paving nepakati Here?

Nei Vagadziri Vari Kuchinja Kunzvimbo Inotakurika Inopisa Inosanganiswa Asphalt—Uye Iwe Unogonawo

Chirimo chega chega, madhipatimendi emigwagwa mikuru nemidziyo yekuvaka pachivande inosangana nemusoro mumwe chete: mitengo yekutakura zvinhu inoramba ichikwira ukuwo mahwindo ebasa achiramba achidzikira. Pinda mufekitori yeasphalt inotakurika , inokweva, inozvivaka yoga inovimbisa musanganiswa mutsva mukati memaminitsi makumi maviri ekusvika. Zvinonzwika zvine ushingi, handiti? Asi data renyika reDOT kubva kuTexas neGeorgia rinoratidza kuti makontrakita anoderedza 18–24% kubva pamari inoshandiswa nezvinhu mushure memwaka wekutanga. Chakavanzika hachisi cheuroyi; chiri kubvisa rwendo rwemakiromita makumi matanhatu kuenda kumotokari yekuomesa iri pedyo. Marori mashoma ari mumugwagwa, dhiziri shoma, uye—heino chinhu chinoshamisa—hapana musanganiswa wehusiku "wakapfava" unofanirwa kudziiswazve mangwanani anotevera.

Tekinoroji Inoshanda Sei Pakufamba?

Mira, Ko Nezve EPA Permits?

Mubvunzo wemamiriyoni emadhora. Mazhinji emhando dzeasphalt plant dzinofambiswa dzinotumirwa neEPA "General Air Quality Permit for Minor Sources" dzakagadzirwa kare. Dudziro: kana kugadzirwa kwako kukaramba kuri pasi pematani 100,000 pagore uye uchipisa gasi repaipi kana dhiziri re ultra-low-sulfur, unenge uri munzira yekukurumidzira. Mamwe matunhu achiri kuda chiziviso chemazuva makumi matatu, asi izvozvo zvinopfuura saga yemwedzi gumi nemisere inodiwa kune nzvimbo ye400-tph stationary. Zano rehunyanzvi: chengeta kopi yevimbiso yeutsi hwemhepo yemugadziri mubhokisi remagirovhosi; vaongorori vanofarira kuona "≤0.04 lb PM-10 patani" yakanyorwa nemabhii matema Arial.

Kubudirira muNhamba: ROI muMwaka Mumwe Chete

Ngatiite masvomhu mashoma pachirongwa chekugadzirisa migwagwa yedunhu chemakiromita maviri:

• Avhareji yekutakura (nzvimbo isingamire): makiromita makumi mana nemaviri → $11.30 patani mukutakura zvinhu.
• Huremu hunodiwa: matani 18,000.
• Kupisa kwakanyanya kwekunonoka kwekupera kwevhiki: 3%.

Mari yose yekuwedzera: ≈ $230,000. Chivako cheasphalt chinotakurika chine hot mix chiri pakati nepakati chinorendwa ne $35,000 pamwedzi, kusanganisira calibration. Kunyangwe ukachichengeta kwemwedzi mitatu, uchiri kubhadhara $125,000 mu black—usati waverenga mabhonasi ekushanda husiku kana zvirango zvekudziya muviri.
