Xagee Heerkulka Asphalt ku shidi karaa

Asphalt waa la shidi karaa waa haddii heerkulka deegaanku si ku filan sare ugu kacayo. Marka heerkulku ka sarreeyo 300°C, asphalt-ka dabiiciga ahi waxa uu maraa kala-goynta kulaylka, soo saarida unugyo fudud oo fududeeya gubashada.

Goobaha sifaynta, daamurku waa guban kara heerkul ka sarreeya 600°C. Marka daamur Waxyaabaha ku jira shubka asphalt ayaa ka badan 25%, qiimihiisu calorifik ah ayaa ka badan 1500kcal/kg, oo la mid ah qiimaha kulaylka dhuxusha dhagaxa ee laga helo gobolka Jiande ee Zhejiang.

Waxa kale oo ay ku gubanaysaa xaaladaha injineernimada ee habboon (heerkulku wuu dhamaaday 800 shahaadooyinka, si fiican loo shiiday, si fiican isku qasan, ku filan ogsijiin, iwm.), in kasta oo la gaadho gubashada dhamaystiran way adkaan kartaa.
