粘接完成后，即可通车。
可以采用人工用橡皮锤敲打道路用快速贴边缘或机械碾压至与沥青路 面密实贴合。
对根据本发明上述实施例获得的道路用快速贴进行性能评价，评价试验如下。
1.高温性能试验
道路用快速贴的高温性能主要是通过生产道路用快速贴的主要材料的高温性能来评价，只要主要材料达到了实际的路用要求，则该道路用快速贴即可满足要求，因此道路用快速贴的高温评价只针对其主要材料进行，本发明中的道路用快速贴的主要材料为高粘改性沥青和防裂纤维布，高粘改性沥青的技术指标采用现有改性沥青的评价方法进行评价，本发明的高粘改性沥青的评价试验结果与现有改性沥青的产品技术要求如表1所示。表1中，注：软化点的测定按照沥青软化点T0606执行，针入度测定按照沥青针入度T0604执行，延度的测定按照沥青延度T0605执行，粘度测定按照T0625执行，闪点测定按照沥青闪点T0611执行。
由表1中的数据可以看出，本发明高粘改性沥青的软化点、针入度、延度、粘度和闪点均达到了现有改性沥青的产品技术要求，同时可以看出，本发明高粘改性沥青的针入度为80，说明本发明高粘改性沥青较柔软，本发明高粘改性沥青的软化点达到90℃，说明本发明高粘改性沥青具有较好的耐高温性能，另外，防裂纤维布可经受220℃以上的高温不变形，由此说明本发明中的快速贴具有较好的耐高温性能。
2.磨耗性试验
将实施例1、实施例3、实施例4和实施例7得到的高粘改性沥青根据实施例8所述方法制备得到的道路用快速贴进行磨耗性测试，磨耗性测试是对道路用快速贴上碎石的粘附性以及抗车轮磨耗能力的评价，碎石采用玄武岩碎石，玄武岩碎石嵌入浸染过高粘改性沥青的防裂纤维布的深度为玄武岩碎石大小的三分之一。试验结果显示，本发明的道路用快速贴的磨耗性试验数据为磨耗损失为8.2％至8.6％。
本发明所述的道路用快速贴的磨耗损失仅为8.2％至8.6％，这表明了道路用快速贴与路面、道路用快速贴自身的沥青-石料间良好的粘附性，使本发明所述的道路用快速贴具有着优异的抗车轮磨耗能力。
3.摩擦系数测定
公路的最大特点之一是行车速度快，车辆的高速行驶对路面抗滑安全 性提出了严格的要求。反映路面抗滑能力的重要技术指标是路面的摩擦系数值，本发明所述的道路用快速贴处理病害路面时，必定会大面积粘贴于病害路面，因此本发明所述的道路用快速贴的摩擦系数显得尤为重要，由于实施例7得到的高粘改性沥青具有比较好的高温性能、抗车轮磨耗能力和低温延展性，因此，以实施例7得到的高粘改性沥青根据实施例8所述方法制备得到的道路用快速贴的摩擦系数如表2所示。采用摆式仪测定摩擦系数值，测试三点，取平均值。
通过表2可以看出，粘贴于病害路面的本发明所述的道路用快速贴即使经历了大量的车辆重复作用后，本发明所述的道路用快速贴仍具有极高的摩擦系数，BPN值为78.3，提高公路路面抗滑性能可以有效地减少追尾、滑溜等撞车事故的发生，提高了行车安全系数。
同时，在温度为－40℃时，本发明中的道路用快速贴具有良好的低温延展性。本发明的道路用快速贴能够用于水泥、钢板、沥青路面，亦可用于封层罩面等施工前的基础预处治。本发明的道路用快速贴不受温度及周边环境的限制，能100％的与病害处治面(病害路面)粘合，施工完毕区域，不开裂，对病害路面完全封层。
压缝带只能对沥青路面的横向裂缝或纵向裂缝进行修补，而本发明所述的道路用快速贴是针对龟网裂、麻面等病害进行大面积式的修补，因此，压缝带与本发明所述的道路用快速贴的处理对象不同。
综上所述，本发明中的道路用快速贴具有较好的高温性能、优异的抗车轮磨耗能力、极高的摩擦系数和良好的低温延展性，使本发明所述的道路用快速贴与病害路面紧密贴合，有效对病害路面进行修补，使本发明所述的道路用快速贴与病害路面形成密实的连接体，加强病害路面的强度，加强了网裂区域的整体强度，防止龟网裂、麻面等病害继续恶化成坑槽等严重病害，并对路面病害起到完全封水的作用；再者，采用本发明所述的道路用快速贴对病害路面修补后，可有效延长道路使用寿命，使用寿命可延长5年至8年，本发明上述实施例所述的道路用快速贴比采用现有修补方法更能延长道路的使用寿命，适用性更广，尤其是温差大的地区；另外，本发明所述的道路用快速贴对龟网裂、麻面等病害路面进行修补时，施工时间短于传统修补方法，无需大型设备，施工简便，裂缝粘贴完毕后即可通车，能够随时随地的修补裂缝，不会对原有沥青路面产生破坏。因此， 本发明所述的道路用快速贴具有更广泛的应用前景。
以上技术特征构成了本发明的实施例，其具有较强的适应性和实施效果，可根据实际需要增减非必要的技术特征，来满足不同情况的需求。
