Ithangi le-asphalt:
1. Ithangi le-asphalt kufanele libe nokusebenza okuhle kokufakwa kwe-thermal, futhi izinga lokushisa kwe-asphalt lokwehla njalo ngamahora angama-24 akufanele lidlule u-5% womehluko phakathi kwezinga lokushisa letiyela kanye nezinga lokushisa elizungezile.
2. Ithangi le-asphalt elingu-500t kufanele libe nendawo yokushisisa eyanele ukuze kuqinisekiswe ukuthi itiyela elinamandla omjikelezo omfushane lingaqhubeka nokuhlinzeka ngetiyela elingaphezu kuka-100℃ ngemva kokushisisa amahora angu-24 endaweni yokushisa engu-25℃.
3. Ithangi lokushisa eliyingxenye (ithangi ethangini) akufanele libe ne-deformation ephawulekayo ngemva kokuthwala umphumela wokucindezela.

Ithangi lokushisisa i-asphalt:
1. Ithangi le-asphalt lokushisa eliphezulu kufanele libe nokusebenza okuhle kwe-thermal insulation, futhi izinga lokushisa le-asphalt lokwehla njalo ngehora akufanele lidlule u-1% womehluko phakathi kwezinga lokushisa letiyela kanye nezinga lokushisa elizungezile.
2. I-asphalt ethangini lokushisa lomthamo wesifunda esifushane ngaphakathi kwe-50t kufanele ikwazi ukushisisa ukusuka ku-120℃ ukuya ngaphezulu kuka-160℃ phakathi kwama-3h, futhi izinga lokushisa lokushisa lingalungiswa ngokuthanda kwakho.
3. Ithangi lokushisa eliyingxenye (ithangi ethangini) akufanele libe ne-deformation ephawulekayo ngemva kokuthwala umphumela wokucindezela.
