| 摘要： | This paper presents information on laboratory tests conducted to determine the effects of additives on the stabilization of unpaved road surfaces. Laboratory tests can be an efficient method of determining which additive will best stabilize a given unpaved road surface, but correlation between laboratory tests and road applications is necessary. For the three soils and three chemical additives tested, lignin sulfonate produced the greatest changes in unconfined compressive strength. However, inspection of an application of lignin sulfonate to a road surface did not show the increase in stability indicated by laboratory tests. This failure of lignin sulfonate to perform as expected is the result of the method of application, and the high solubility of lignin sulfonate. |
