HDPE塑料轨枕比木质轨枕更容易接受现在的轨枕规格生产和使其表面变“毛”,从而安装在路基上后不会滑动。宾夕法尼亚洲的铁路咨询说,HDPE塑料轨枕横向滑动能优于木质轨枕。
华盛顿特区运输局的工地工程师指出,HDPE塑料轨枕可以根据轨道转向和交叉的要求做得长一些,而要得到24英尺长的木料十分困难。塑料轨枕另一个吸引人的优点是安装方便,可以直接使用与木质轨枕要求相同的设备和紧固件,另外,塑料轨枕和木质轨枕可以间隔混合使用。
HDPE plastic sleeper is more likely to accept the current sleeper specification and make its surface "fur" than the wooden sleeper, so that it will not slip after it is installed on the roadbed. HDPE plastic sleeper slides can be better than wooden sleeper, says a rail consultant in Pennsylvania.
Washington, d.c., transport site engineer pointed out that the HDPE plastic sleeper can do it according to the requirement of the rail steering and cross much longer, and the quality of wood is very difficult to get 24 feet long. Plastic sleeper is another attractive advantage is easy installation, can be used directly and require the same equipment and wooden sleeper fasteners, in addition, the plastic sleeper and wooden sleeper interval can be mixed use.
HDPE塑料轨枕正在向铁路长期使用的木质轨枕发起挑战,我国大量运输系统和主要运输干线正在大量安装HDPE塑料轨枕。HDPE塑料轨枕已被广泛接受和认可
聚乙烯塑料轨枕虽然在国内应用少,但在欧洲已成功使用了二十多年。奥地利为它的国内城市运输系统生产了强化的聚氨基甲酸乙酯轨枕,自此以后,这种塑料轨枕逐渐被应用在意大利的米兰、瑞士的苏黎世和联邦德国的汉诺威等运输线路上。
塑料轨枕正在被推荐用于无碴桥梁和高架桥结构上,有利于减少恒载。
现在欧洲和北美的运输系统正在进一步地研究塑料轨枕。
