跑道跑道runway供飞机起飞时加速和着陆时减速滑跑用的带状地面。航空港内飞行区的重要组成部分。跑道道面有土质的、草皮的和人工铺筑的。前两种仅供农用飞机和小型飞机使用；后者有沥青胶结粒料道面、混凝土道面和钢筋混凝土道面，供运输机使用。为保证飞机安全，跑道两端铺筑有端安全道，两侧设道肩和侧安全道。跑道具有一定的方位、长度、宽度、坡度、平坦度、强度和粗糙度。方位主要根据当地风的恒风向、附近障碍物的位置以及地形、地貌、工程地质等条件确定。长度主要决定于起降的主要机型在标准大气条件下的技术性能，以及当地的标高、地形坡度、气温和风等因素。宽度决定于飞机主起落架外轮轮距，并要加一定富余宽度。国际民用航空组织和中国民航总局规定，不同等级飞行区的跑道的最小宽度为18～45米。坡度要便于排水和减少修建工程量，变化宜小，变化次数宜少，要保证飞机驾驶员至少能通视跑道长度的一半。平坦度关系旅客的舒适和飞机起落架等结构的安全。强度要满足飞机荷载的要求。粗糙度决定于跑道的选材及施工方法。一定的粗糙度可使机轮与道面间产生一定的摩擦力，从而防止在某些条件下飞机机轮打滑、失控。跑道道面上用鲜明的白色、黄色材料标示出跑道号码、中线、边线、入口等，并设置灯光系统，给飞机驾驶员提供目视引导信号。运动场中供竞走和赛跑用的路以及速度滑冰用的路也称跑道。田径运动的“径”即指跑道。
