在养鱼地区,螺蛳壳是每年从鱼池中清理出来的废品。过去曾试用作为承重层和保护层材料,但因颗粒小,承重力不足,容易沉陷;用作松散保护层则容易被车轮辗压成粉末,使用周期太短,都没有成功。自1964年11月起,苏州工区先后在木东线9～27公里泥结碎砖路面上铺筑了18公里螺蛳壳的凝固磨耗层,压实厚度2～2.5厘米。铺筑至今,最长的已10个月,经每日平均行车密度40～50车次的实际使用考验,质量很好。螺蛳壳磨耗层主要优点是:(1)就地取材,是无砂石河网地区解决养路材料的好办法,养路成本低;(2)螺蛳壳水稳定性强,完整的螺蛳壳经压实后嵌合
In the area of fish farming, snail shell is a waste product that is cleared from the pond every year. In the past, it was tried as a bearing layer and a protective layer material. However, due to its small particle size and insufficient bearing capacity, it was easily subsided. When used as a loose protective layer, it was easy to be rolled into a powder by a wheel and its service life was too short to succeed. Since November 1964, the work area of Suzhou has paved 18 km of solidified wear layer of snail shells on compacted and broken brick pavements 9 to 27 km away from the east of the wood block, compaction thickness of 2 to 2.5 cm. Paved so far, the longest has been 10 months, the daily average driving density of 40 to 50 trips on the actual use of the test, the quality is very good. Spiral shell abrasion layer main advantages are: (1) the local material, is no sand stone river network area to solve the problem of road maintenance materials, low maintenance costs; (2) snail shell water stability, the integrity of the shell after compaction Chimeric
