Qaybta wadista waa mid ka mid ah qaybaha muhiimka ah ee warshadda isku dhafka ah ee asphalt, markaa haddii si la isku halleyn karo loo shaqeyn karo waa in aad loo qiimeeyaa si looga fogaado saameynta xun ee dhammaan dhirta isku dhafka ah ee asphalt. Si loo hubiyo in qaybta wadista ee warshadda isku dhafka ah ee asphalt ay tahay mid dhameystiran oo la isku halayn karo, tallaabooyinka dayactirka ee soo socda ayaa lagama maarmaan ah.

Waxa ugu horreeya ee ay tahay in fiiro gaar ah loo yeesho waa qaybta wareega caalamiga ah ee unugga wadista ee warshadda isku dhafka ah ee asphalt. Qaybtani waxay had iyo jeer ahayd qayb khaladka u nugul. Si loo yareeyo cilladaha, waa in dufan lagu daraa waqtigii loogu talagalay, si joogto ah loo hubiyo xirashada, oo la hagaajiyo oo la beddelo waqtiga. Isticmaalayaashu waa inay sidoo kale diyaariyaan golaha usheeda dhexe ee caalamiga ah si ay uga fogaadaan inay saameeyaan habka shaqada ee dhammaan dhirta isku dhafka asphalt.
Marka labaad, nadaafadda saliidda biyo-biyoodka ee loo isticmaalo warshadda isku dhafka asphalt waa in la hubiyaa. Ka dib oo dhan, deegaanka shaqada ee qalabku waa mid aad u adag, sidaas darteed waa lagama maarmaan in laga hortago wasakhda iyo dhoobada inay soo galaan nidaamka hydraulic. Saliidda hydraulic sidoo kale waa in si joogto ah loo beddelaa iyadoo loo eegayo shuruudaha buug-gacmeedka. Marka la helo biyo ama dhoobo isku dhafan oo ku jira saliidda hydraulic inta lagu jiro kormeerka, nidaamka hydraulic waa in isla markiiba la joojiyaa si loo nadiifiyo nidaamka hydraulic loona beddelo saliidda.
Maaddaama uu jiro nidaamka hawo-mareenka, dabcan, qalabka qaboojinta ayaa sidoo kale loo baahan yahay, taas oo sidoo kale ah diiradda muhiimka ah ee nidaamka wadista geedka isku dhafka asphalt. Si loo hubiyo in hawsheeda ay si buuxda u shaqayn karto, dhinaca kale, hiitarka saliidda biyaha waa in si joogto ah loo nadiifiyaa si looga hortago in hiitarka uu xannibo sibidhka; Dhanka kale, marawaxada korantada hiitarka waa in la hubiyaa si loo arko in uu si caadi ah u shaqaynayo si looga hortago in heerkulka saliidda hadhiyrooliga uu dhaafo heerka caadiga ah.
Guud ahaan, ilaa iyo inta saliidda haydarooliga ee qalabka wadida geedka asphalt lagu qaso nadiif ah, guud ahaan waxaa jira khaladaad yar; laakiin nolosha adeeggu way ku kala duwan tahay soo saaraha ilaa soo saaraha, markaa fiiro gaar ah u yeelo indha-indheynta alkalinity oo beddel waqtiga dhabta ah.
