随着高等级、重交通道路的不断发展,要实现安全、舒适、高速的目的,路面抗滑,特别是雨天路面抗滑是关键的技术问题之一,必须引起科研、设计、施工等方面的高度重视。据报道,广东207国道某200m长路段,1987年春的雨季中,有一天发生交通事故9起,创我国单位长度路段内的交通事故率之最。江苏淮扬二级公路高邮县某段500m长路段内,在1987年6月1日、6月13日二个雨天,发生交通事故11起,死1人,伤数人,直接经济损失达10万元以上。宁六公路雨天事故占48％,上
With the continuous development of high-grade and heavy-traffic roads, it is one of the key technical issues to resist slippery, especially for rainy days, in order to achieve safety, comfort and high-speed. It must cause scientific research, design and construction highly valued. It has been reported that a 200-meter-long section of State Road 207 in Guangdong Province and a rainy season in the spring of 1987 happened 9 times a day, creating the highest rate of traffic accidents within the unit length of our country. Within a 500-meter long section of Gaoyou County, Jiangsu Huaiyang Grade II Highway, 11 traffic accidents occurred on two rainy days on June 1, 1987 and June 13, 1987, killing one person and injuring several people. The direct economic loss amounted to 10 Million or more. Ningliu Road rainy days accounted for 48% of accidents, on
