摘　　要：根据寒冷地区气候条件下道路混凝土受冻融循环作用特点,以验证从通辽燃煤火力发电厂排出的粉煤灰用在混凝土道路的实用性为目的,阐述了掺粉煤灰道路混凝土受冻结融解作用后的耐磨耗性。试验结果表明,掺粉煤灰道路混凝土受冻融作用后,表面受到冻融的剥离作用露出了粗集料,在粗集料抵抗磨耗的情况下,粉煤灰取代率对耐磨耗性的影响不大。According to the characteristics of freeze-thaw cycle action in road concrete under the weather condition in cold area,the paper describes the abrasion resistance of road concrete with highway fly ash after being frozen and dissolved with the view of checking the practical applicability that using the highway fly ash from Tongliao coal-fired power plant in concrete road.The test result shows that the surface reveals coarse aggregate because of peeling effect,but the replacement rate of coarse aggregate has little effect on abrasion resistance under the condition that coarse aggregate resists abrasion.
