路面的渗水试验是沥青路面施工质量检查的主要指标之一。长期以来,主要用油腻子作为密水的材料。但油腻子涂抹困难,操作不便,影响试验效果,为选用较理想的密水材料,我们曾分别选用了油腻子、润滑脂(黄油)、重粘土、橡皮泥和普通洗衣肥皂作了一些比较试验。从使用效果来看,用肥皂试验数据较稳定,是做路面渗水试验的密水材料较为理想的。 Water seepage test of pavement is one of the main indexes of asphalt pavement construction quality inspection. For a long time, the main use of oil putty as a dense material. However, the application of oil putty is difficult, the operation is inconvenient and the test effect is affected. In order to select the ideal dense water-based material, we have made some comparative experiments with greasy oil, grease (butter), heavy clay, plasticine and ordinary laundry soap . From the use of results, the soap test data is more stable, is to do pavement water seepage test of the more ideal material.
