Abstract

ABSTRACT A preliminary statistical analysis of 914 mostly Transvaal soils of average selected subgrade quality produced useful, highly statistically significant methods for the prediction of the maximum Proctor CBR and the Proctor compaction characteristics, as well as relationships between soaked and unsoaked CBR and between Proctor and MAASHO compaction characteristics. Because of the well-known poor reproducibilty of the CBR, as well as the indicator tests used, it is believed that the accuracy of the prediction methods is better than it appears from the large scatter of results. These methods do not replace CBR testing but supplement it by possibly reducing the number of expensive tests and providing a check on gross errors. Keywords: CBR, prediction, indicator tests, subgrade, Proctor

从指标性质预测德兰士瓦土的加州承载比和压实特性

摘要：对914种主要为德兰士瓦州平均选定路基质量土壤的初步统计分析，为预测最大Proctor CBR和Proctor压实特性，以及浸泡和未浸泡CBR之间以及Proctor和MAASHO压实特性之间的关系，提供了有用的、具有高度统计意义的方法。由于众所周知CBR的可重复性较差，以及所使用的指标测试，人们认为预测方法的准确性要好于结果的分散性。这些方法并不取代CBR测试，而是通过可能减少昂贵测试的数量和提供对严重错误的检查来补充CBR测试。关键词：CBR，预测，指标试验，路基，Proctor

期刊介绍： The Journal of the South African Institution of Civil Engineering publishes peer reviewed papers on all aspects of Civil Engineering relevant to Africa. It is an open access, ISI accredited journal, providing authoritative information not only on current developments, but also – through its back issues – giving access to data on established practices and the construction of existing infrastructure. It is published quarterly and is controlled by a Journal Editorial Panel. The forerunner of the South African Institution of Civil Engineering was established in 1903 as a learned society aiming to develop technology and to share knowledge for the development of the day. The minutes of the proceedings of the then Cape Society of Civil Engineers mainly contained technical papers presented at the Society''s meetings. Since then, and throughout its long history, during which time it has undergone several name changes, the organisation has continued to publish technical papers in its monthly publication (magazine), until 1993 when it created a separate journal for the publication of technical papers.
