摘要
采用抗凝冰复合材料对准噶尔盆地S21公路段某桥段进行涂层试验,基于复配-初步混合-高分散处理-涂层作业-涂层补缺-自然风干工艺,达到抗凝冰涂层高效施工的目的。施工结束后,在试验段进行路用性能检测,结果显示,未涂布抗凝冰路面静摩擦系数为67.1,涂布抗凝冰涂层路面摩擦系数为58.2,说明抗凝冰涂层会降低路面静摩擦系数;未涂布和涂布数据分别为0.89和0.78,说明路面涂布后,粗糙度下降,进而降低了路面的摩擦系数。涂布后的路面渗水系数大大下降,从86 mL/min下降到30 mL/min。冬季降雪后,涂布抗凝冰涂层路面与未涂布的相比未见明显积雪,路面摩擦系数由夏季的58.00下降至55.68,降幅仅为4%,可能为路面积水所导致,但均满足设计要求。
The anti-icing composite material was used to carry out coating test on a bridge section of S21 highway section in Junggar Basin.Based on the process of compounding-preliminary mixing-high dispersion treatment-coat⁃ing operation-coating filling-natural air drying,the purpose of efficient construction of anti-icing coating was achieved.After the construction,the road performance test was carried out in the test section.The results show that the static friction coefficient of the uncoated anti-icing pavement is 67.1,and the friction coefficient of the coated an⁃ti-icing coating pavement is 58.2,indicating that the anti-icing coating will reduce the static friction coefficient of the pavement.The uncoated and coated data were 0.89 and 0.78,respectively,indicating that the roughness of the road surface decreased after coating,thereby reducing the friction coefficient of the road surface.The water permea⁃bility coefficient of the road surface after coating is greatly reduced,from 86 mL/min to 30 mL/min.After the snow⁃fall in winter,there was no obvious snow cover on the coated anti-icing coating pavement compared with the uncoat⁃ed pavement.The friction coefficient of the pavement decreased from 58.00 in summer to 55.68,with a decrease of only 4%,which may be caused by the water in the road area,but all meet the design requirements.
