style="text-indent:25px">幾種鋼橋面鋪裝的比較：編輯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上，都有明顯的區(qū)別。從許多國家實際應(yīng)用情況來看，在使用性能和使用壽命方面，以環(huán)氧瀝青鋪裝比較好，北京正規(guī)鋼橋設(shè)計購買，澆注式瀝青和SMA 次之，普通瀝青較差。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，但對溫度、時間控制非常嚴(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。在工程造價方面，如以同樣厚度相比較，則環(huán)氧瀝青鋪裝成本比較高，澆注式瀝青鋪裝次之，SMA 比普通瀝青費用約增加20 % ～30 % ，但比環(huán)氧瀝青和澆注式瀝青為低。然而，北京正規(guī)鋼橋設(shè)計購買，環(huán)氧瀝青因強度高，鋪裝層因此可以減薄，減輕了自重，又有利于降低造價；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。鋼橋是**、輕型薄壁結(jié)構(gòu)，北京正規(guī)鋼橋設(shè)計購買，截面和自重比混凝土橋小，跨越能力大。北京正規(guī)鋼橋設(shè)計購買</p><div
