测试方法：testing method:
第一步，采用路面加载方式对路面封层进行加载，如摆式仪等；The first step is to load the pavement seal layer by means of pavement loading, such as pendulum instrument, etc.;
第二步，采用高速摄像机记录路面封层力致发光图片，并且计算受力面积；The second step is to use a high-speed camera to record the mechanoluminescent picture of the pavement seal and calculate the force-bearing area;
如摆式仪加载，则受力面积＝橡胶片长度×橡胶片滑动距离＝7.62cm×12.6cm＝96.012cm2；If the pendulum instrument is loaded, the force bearing area = length of the rubber sheet x sliding distance of the rubber sheet = 7.62cm x 12.6cm = 96.012cm 2 ;
第三步，通过MATLAB对发光图片进行处理，采用二值化处理的方式对图片进行处理，计算发光面积；The third step is to process the luminous picture through MATLAB, and process the picture by binarization to calculate the luminous area;
第四步，根据发光效率计算公式计算发光效率；The fourth step is to calculate the luminous efficiency according to the luminous efficiency calculation formula;
第五步，对路面封层进行不同次数打磨，测定路面封层力致发光性能。The fifth step is to polish the pavement sealing layer for different times, and measure the mechanical luminescence performance of the pavement sealing layer.
发光效率计算公式：Luminous efficiency calculation formula:
发光效率＝发光面积/受力面积×100％Luminous efficiency = luminous area/forced area × 100%
具体试验过程及结果见表1：The specific test process and results are shown in Table 1:
表1不同打磨次数下的路面封层发光效率Table 1 Luminous efficiency of pavement sealant under different sanding times
参见图1和表1，具有力致发光性能的路面封层在打磨后，受到外力的情况下，能够将机械能转化为光能表现出来；并且具有力致发光特性的路面封层力致发光性能较好，经过打磨后，发光性能有所提高，主要是因为乳化沥青胶结料为黑色，力致发光粉的发出光被部分沥青遮盖住，表层乳化沥青被磨耗掉，裸露出内部力致发光材料，其力致发光性能有所提高，具有较好的长效性。Referring to Figure 1 and Table 1, the pavement sealant with mechanoluminescent properties can convert mechanical energy into light energy under the condition of external force after being polished; Better, after polishing, the luminous performance is improved, mainly because the emulsified asphalt binder is black, the light emitted by the mechanoluminescent powder is covered by part of the asphalt, and the emulsified asphalt on the surface is worn away, exposing the internal mechanoluminescent material , its mechanoluminescent performance has been improved, and it has a good long-term effect.
本发明针对感知型路面建设需求，采用路面封层的技术，直接将力致发光材料应用于感知型路面材料设计中，大大降低了力致发光路面对于原材料和施工工艺的需求，同时兼顾了力致发光路面的路用性能，克服了其应用于柔性沥青路面上的不足。并且创新性的引入反光粉，在力致发光路面封层中构成光传导路径，使得力致发光材料所发光源能够由封层内部传导至路面表面。但本发明不仅仅是将发光层与透光层合并，因为若直接将两者合并，会导致力致发光材料磨耗而长效性不足，并且为保障发光特性，力致发光材料用量过大引起费用增加。Aiming at the demand for perceptual pavement construction, the present invention adopts the technology of pavement sealing layer, and directly applies mechanoluminescent materials to the design of perceptual pavement materials, which greatly reduces the demand for raw materials and construction techniques of mechanoluminescent pavement, and at the same time takes into account the force The road performance of the luminescent pavement overcomes the shortcomings of its application on the flexible asphalt pavement. And innovatively introduce reflective powder to form a light transmission path in the mechanoluminescent pavement sealing layer, so that the light source from the mechanoluminescent material can be transmitted from the inside of the sealing layer to the road surface. However, the present invention is not only to combine the luminescent layer and the light-transmitting layer, because if the two are directly combined, the mechanoluminescent material will be worn out and the long-term performance will be insufficient, and in order to ensure the luminescent characteristics, the excessive amount of mechanoluminescent material will cause Fees increase.
本发明是针对高速公路的应用场景，基于感知型路面建设获取路面信息的技术目标，通过路面封层的施工方式，最终获得的路面能够满足车辆测重的力致发光材料-路面材料的应力应变需求，或是用于测速的长期磨耗需求。The present invention is aimed at the application scene of the expressway, and is based on the technical goal of obtaining road surface information based on perceptual road surface construction. Through the construction method of the road surface sealing layer, the finally obtained road surface can meet the stress and strain of the mechanoluminescent material-pavement material for vehicle weight measurement. requirements, or long-term wear requirements for speed measurement.
