style="text-indent:25px">幾種鋼橋面鋪裝的比較：不同瀝青鋪裝材料用于鋼橋面鋪裝，不僅在性能上而且在施工工藝以及在工程造價(jià)上，都有明顯的區(qū)別。從許多國(guó)家實(shí)際應(yīng)用情況來(lái)看，在使用性能和使用壽命方面，以環(huán)氧瀝青鋪裝好，澆注式瀝青和SMA 次之，普通瀝青差。在施工工藝方面，環(huán)氧瀝青混合料拌制工藝雖不是太復(fù)雜，但對(duì)溫度、時(shí)間控制非常嚴(yán)格；澆注式瀝青工藝比較特別，需要特殊的拌制設(shè)備；SMA 只是比普通瀝青路面復(fù)雜一些。在工程造價(jià)方面，如以同樣厚度相比較，則環(huán)氧瀝青鋪裝成本高，澆注式瀝青鋪裝次之，SMA 比普通瀝青費(fèi)用約增加20 % ～30 % ，但比環(huán)氧瀝青和澆注式瀝青為低。然而，環(huán)氧瀝青因強(qiáng)度高，鋪裝層因此可以減薄，減輕了自重，又有利于降低造價(jià)；澆注式瀝青鋪裝層厚度也較薄，或與普通瀝青鋪裝復(fù)合使用。上海正規(guī)鋼橋深化設(shè)計(jì)軟件服務(wù)鋼橋長(zhǎng)效防腐的設(shè)計(jì)應(yīng)考慮的因素在進(jìn)行鋼結(jié)構(gòu)涂裝設(shè)計(jì)。</p><div
