style="text-indent:25px">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)氧瀝青鋪裝較好，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雜，但對溫度、時間控制非常嚴格；澆注式瀝青工藝比較特別，需要特殊的拌制設備；SMA只是比普通瀝青路面復雜一些。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，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合使用。建成的橋梁要保證使用年限，并便于檢查和維護。正規(guī)鋼橋深化多少錢</p><p
