摘要從有彈簧懸吊的車輛動力之觀點,證實公路超高或曲線半徑的設計準則並不能滿 足廣泛的要求。事實上,超高設計原本就有其種種之限制。因此,在本研究中吾人描述一種 差異舖面摩擦之設計以抗衡超高佈設之不足。此種佈置主要係於公路彎道上之各車道之左右 半面提供某一程度的不同舖面摩擦而言。其功能為促使車輛行駛更穩定,乘客更舒適。這種 佈設沒有像佈設超高的缺點以致有其設限:超高在壞天氣時可能會致使車輛產生側滑意外。本 文繪列出不同設計速度及不同曲率半徑下之應有的相對差異摩擦係數值,至於如何在舖面上 實現差異性摩擦則做了一些舖面材料級配方面的選擇介紹分析。最後鄭重地提醒若建造此差 異摩擦路面應注意的相關安全問題。;From the perspective of sprung vehicle dynamics, the design criteria of superelevation or radius is unsatisfactory for broad requirements. Superelevation design has many limitations. Therefore, in this study, we describe a split layout of pavement friction, designed to counterbalance an insufficiency of superelevation. The layout is to provide different friction pavements between the left and the right sides of a lane in curves. Such a layout would cause vehicles to be more stable, in addition to providing passengers with more comfort. There is no deficiency of placing superelevations, of which the inclined cross-sections possibly cause side slipping in bad weather conditions. Also, the ideal values of friction difference for high design speeds versus various radii are illustrated. How to implement a split friction pavement is also introduced accompanied by an analysis of the selection of materials or aggregates. Finally, a special consideration regarding safety for constructing such a pavement is mentioned.
