-30 ° C illaa 50 ° C: Sidee loo ciqaabayaa Ciyaaraha Cool Clatch
Waqtiga siideynta:2025-08-07
Asphalt asphalt (qabow qabow) oo laga soo bilaabo asphalt asphalt-ka-dhabadeed ayaa ku mahadsan in injineeriyada horumarsan ee u oggolaanaya in ay ka adkaato kuleylka iyo qaboojinta qoto dheer. Waa tan sayniska ka dambeysa adkeysiga:
1. Powermer Poweruse
Digada qabowga ayaa iskudhafan danaashayaasha polymer-wax laga beddelay iyo waxyaabo lagu daro oo dabacsan oo ka dabacsan heerkulka xad-dhaafka ah (-30 ° C illaa 50 ° C). Si ka duwan kuwa kulul-isku-darka (HMA), oo dildilaaca cimilada qabow iyo jilicsanaanta kuleylka, kuwan ku-dadaashani waxay la qabsadaan walaaca fekerka. Waxay u diidaan jaranjarada inta lagu gudajiro wareegga-qaboojiyaha oo ka hortagaya kor u qaadida ka hooseeya qorraxda.
2. Biyo-dhimista & cimilada oo dhan
HMA waxay u baahan tahay xaalado qalalan, diiran oo loo dejiyo. Si kastaba ha noqotee, si kastaba ha noqotee, isla markiiba u hogaansanaato qoyan, barafka, ama sagxadaha qabow - - baraf, baraf, ama biyo taagan. Qaaciddadeeda hydrophobic waxay diiday qoyaan, hubinta dayactirka inuu si dhakhso leh ugu xajisto tuubooyinka fatahaada ama wadooyinka barafka leh.
3. Waxaa lagu xoojiyay adkaynta
Qalabka qabow ee qabowga lagu daro wuxuu ku daraa agabyada sida qalabka loo yaqaan 'Bastal' iyo isku-darka fasalka sare. Naqshadeyntaani waxay kordhisaa iska caabbinta dillaaca dusha sare ee walbahaarka kuleylka, oo si qarsoodi ah u kacaya HMA imtixaannada musiibada. Potholes qoto dheer ayaa ka buuxsamay lakab (mid kasta ≤5CM), oo is dulfuulan ugu badan ee cufnaanta iyo cimri dhererka.
4. Kuleylka eber, eber eber
Kuleylku micnaheedu ma aha wax lagululaado shidaalka inta lagu gudajiro arjiga, kululaynta qiiqa CO₂. Qaaciibadan ayaa sidoo kale adeegsanaya alaabada dib loo warshadeeyo (E.G., taayirrada taayirrada ama asphalt-ka dib loo soo celiyo), yareynta qashinka qashin-qubka inta uu sii wado waxqabadka waddooyinka waaweyn ee Arctic wadooyinka lamadegaanka.
5. Gaadiidka degdega ah, hagaajinta ugu dambeysa
Marka isqarxin, xargaha dhirta ee qabowgu si dhakhso leh ayaa loo qalajiyaa, xitaa -25 ° C blizzards ama 50 ° C kuleylka. Awoodda "set-iyo-go-iyo" waxay yareysaa xiritaanka wadooyinka iyo kharashaadka dayactirka.
Maxay muhiim u tahay
Qalabka 'stral aspt' strass-ka-cimilada-cimilada ka soo baxa chemistry Smart Kimistar: Dambiyayaal dabacsan, oo ah arinta biyaha ka-hortagga ah, iyo arjiga ku habboon. Wadooyinku waxay la dagaallamaan jawiga cimilada, maahan kaliya pat-stick - waa gaashaan waara, waarta.
