    • To lay a running track, a resilient particulate material is spread over a substrate of a given width. Pressure is applied individually downwardly on the material over a plurality of respective segments of the width, as the material is smeared over and amongst the segments to form a bonded layer of said material which exhibits a continuous and even upper surface across said width. This is accomplished by means of a machine that includes an elongated frame of a length sufficient to span a plurality of lanes of a running track. A plurality of successively-hinged individually-articulatable platens depend from and are distributed along the frame. Each platen has a length corresponding generally to the width of respective ones of the lanes. Means included with respect to each of the platens enables the application of pressure on the material toward the underlying substrate of the track. Also included are means for reciprocating the platens laterally and generally across and between the respective ones of the lanes as well as means for moving the machine along the track.
    • 为了铺设跑道,弹性颗粒材料铺展在给定宽度的基材上。 随着材料在片段之间和之间被涂抹,以形成在所述宽度上呈现连续且均匀的上表面的所述材料的接合层,在所述宽度的多个相应部分上向所述材料上单独施加压力。 这通过机器实现,该机器包括长度足以跨越行进轨道的多个通道的长度的框架。 多个连续铰接的单独铰接的压板从框架依靠并分布在框架上。 每个压板具有一般对应于各个通道的宽度的长度。 包括在每个压板上的装置使得能够将材料上的压力施加到轨道的下面的基底。 还包括用于使压板横向地和大致横过并且在相应的车道之间进行往复运动的装置以及用于沿轨道移动机器的装置。
