In 2009, a manually pushed device was developed to measure the dry and wet skid resistance of pavement surfaces at walking pace. The device is based on the same principle as a larger trailer-mounted version and provides a continuous measurement of skid resistance; it is particularly suitable on sites where the survey speed cannot be achieved by trailer- or vehicle-mounted devices. The manually pushed device is also useful for restricted test sections and where the incline, camber or gradient are not desirable for other survey methods. However, the device is not currently covered by a national or international test standard. Its use has also been restricted due to a lack of published research regarding the correlation of results with other methods of measurement. This paper describes on-site testing conducted using the manually pushed device to assess the correlation of the test results with results provided by a trailer-mounted device. The repeatability of the test method and the influence of survey speed on the test results are also examined.

简报：测量路面防滑性——比较手动和拖车安装的设备

2009 年，开发了一种手动推动装置，用于测量步行速度下路面的干湿防滑性能。该设备基于与更大的拖车安装版本相同的原理，并提供防滑性的连续测量；特别适用于拖车或车载设备无法达到测量速度的现场。手动推动装置也适用于受限制的测试部分，以及其他测量方法不希望倾斜、弯曲或坡度的地方。但是，该设备目前未包含在国家或国际测试标准中。由于缺乏有关结果与其他测量方法的相关性的已发表研究，它的使用也受到限制。本文描述了使用手动推动装置进行的现场测试，以评估测试结果与拖车安装装置提供的结果的相关性。还检查了测试方法的可重复性和测量速度对测试结果的影响。
