摘要
为评价不同雾封层材料在公路预防性养护中的使用效果,文章通过在高速公路上设置试验段,分别测定四种不同雾封层材料施工前、施工完成24h及施工完成半年后的渗水系数、摆值及PCI值变化情况进行对比分析。结果表明:四种雾封层材料("沥青王TM"、HAP高性能沥青混凝土路面防护剂、沥青再生王CAP、Star-Seal Supreme)对原路面均能起到一定的封水效果,但摆值均会有不同程度的下降;四种雾封层材料均能在一定程度上改善原路面的使用状况;四种雾封层材料中Star-Seal Supreme的使用效果最好,推荐在公路预防性养护中优先选用。
In order to evaluate the use effect of different fog-sealing layer materials in highway preventive maintenance, by setting the test section on the expressway, this article measured and compared the water seepage coefficient,pendulum value and PCI value variation situation of four different fog- sealing layer materials respectively before construction, 24h and 6 months after construction.The results showed that these four kinds of fog-sealing layer materials（＂Asphalt King TM＂, HAP high performance asphalt concrete pavement protectant, asphalt regeneration king CAP, and Star-Seal Supreme）can all play a certain water-sealing effect on the original road surface, but their pendulum value showed the different decrease;four kinds of fog-sealing layer materials can all improve the use situation of original road surface in a certain extent; in these four kinds of fog-sealing layer materials, Star-Seal Supreme has the best use effect,which is recommended as the preferred choice in highway preventive maintenance.
