Sasobit温拌沥青混合料的路用性能及节能减排效果

Pavement Performance of Sasobit Warm Mix Asphalt and Energy Saving and Emission Reduction Effect

通过车辙试验、低温弯曲试验、浸水马歇尔试验、冻融劈裂试验和疲劳试验研究Sasobit温拌沥青混合料的路用性能;并从燃料消耗、有害气体的排放等方面来分析Sasobit温拌沥青混合料的节能减排效果。研究结果表明:Sasobit温拌沥青混合料的高温稳定性、水稳定性和抗疲劳性均好于热拌沥青混合料,低温抗裂性略差于热拌沥青混合料;Sasobit温拌沥青混合料可明显地节约能源、降低有害气体及粉尘的排放。

Pavement performance of Sasobit warm mix asphalt is studied through rutting test, low- temperature bending test, immersion Marshall test, freeze-thaw cleavage test, and fatigue test, and its energy saving and emission reduction effect is analyzed through fuel consumption and the emission of harmful gases. The experimental results show that its high temperature stability, water stability, and fatigue resistance of the warm mix asphalt are all better than hot mix asphalt, while the low-temperature crack resistance is mildly worse than that of hot mix asphalt; and Sasobit warm mix asphalt can significantly save energy, reduce emission of harmful gases and dust.
