Dab tsi yog qhov zoo ntawm Bitumen tshiab (muaj kev sib xyaw ua ke: Resinition: Nruas)
Bitumen (muaj: Asphalte thiab Resin) Nruas Melting Cib, Kev Tiv Thaiv Kev Ntsuas Kub, Kev Tiv Thaiv Kev Ntsuas Hluav Taws Xob, thiab lwm yam. Txhua yam khoom siv hluav taws xob, ntsuas kub Nruas melting cog nws tus kheej, ua ib qauv txheej txheem tag nrho.

Cov bitumen (sib xyaw: asinionente thiab cob) nruas melting tshuab Asphalt Cov kev sib txuas sib txuas tau muab tso rau sab hauv cov khoom nws tus kheej, uas tau txo qis thermal kev puas tsuaj thiab txhim kho kev siv cua sov.
Cov tshuab pa hluav taws xob kub yaj ua rau cov khoom siv hluav taws xob hnyav (cov khoom siv hluav taws xob uas cuam tshuam nrog cov pa hluav taws thiab cov hmoov av) Cov neeg siv hluav taws xob tshem tawm nrawm nrawm nrawm, vim tias qhov ntsuas kub tau zoo dua li qhov kub ntawm cov roj kub siab; Thiab vim tias kub cua ncaj qha rau basumen (muaj pes tsawg leeg: asinion convection thiab resin) txwj ntau tshaj li qhov kub sov kiv cua coil radiant hom.
