查尔斯顿64/77号州际公路分流处连发三起致命车祸后铺设高摩擦路面
西弗吉尼亚州交通部门正在查尔斯顿分流处（Charleston Split）交汇路段铺设高摩擦路面层，以降低事故率。据《查尔斯顿公报》报道，该路段自今年5月以来已发生三起致命车祸。工程由Truesdell公司承建，合同金额59万美元，范围自东行I-64公路58.5英里处起，预计11月12日前后收尾。查尔斯顿分流处是I-64与I-77号州际公路在卡纳瓦县查尔斯顿市区的交汇点，车流量大、弯道多，雨天打滑事故频发。高摩擦路面通过在原路面加铺高摩擦集料层提高轮胎抓地力，是美国公路安全治理中常用的弯道防滑技术。
High-Friction Surface Treatment Added at Charleston Split After Fatal Crashes
West Virginia transportation crews are applying a high-friction surface treatment at the Charleston Split interchange to cut crashes, the Charleston Gazette-Mail reported Nov. 11. The stretch has seen three fatal crashes since May. The work, performed by Truesdell Corp. under a $590,000 contract, begins at milepost 58.5 on eastbound Interstate 64 and is expected to wrap up this week.
The Charleston Split, where I-64 and I-77 meet in Charleston, Kanawha County, carries heavy traffic through tight curves where wet-weather skidding is common. High-friction surfacing bonds abrasive aggregate to the pavement to improve tire grip and is a standard countermeasure for curve-related run-off-road crashes.
