Reassessment of problems affecting stabilized layers in roads in South Africa

Author: Paige-Green, P Date: Nov 2009 During the early 1980s a number of problems related to the loss of stabilization and disintegration of stabilized layers in roads (lime and cement) were reported in South Africa. This led to many comprehensive investigations and it was shown ... Read more
Recommendations on the use of marginal base course materials in low volume roads in South Africa

Author: Paige-Green, P Date: 04 Jun 2009 An investigation into the performance of 57 sections of road in South Africa identified by the Provincial Road Authorities as being constructed using marginal quality base course materials has been carried out. The investigations has shown ... Read more
Relationship between index testing and California Bearing Ratio values for natural road construction materials in South Africa

Author: Breytenbach, IJ ; Paige-Green, P ; Van Rooy, JL Date: Oct 2010 Research was done to determine whether a relationship can be established between index testing and CBR (California Bearing Ratio) results. The process involved compiling a database of test results for a range of rock material types across ... Read more
The SCS double hydrometer test in dispersive soil identification

Use and interpretation of the dynamic cone penetrometer (DCP) test

Author: Paige-Green, P ; Du Plessis, L Date: Sep 2009 During the early 1930's the California Bearing Ratio test (CBR) was developed for the testing of material strength in the laboratory for the design of pavements. The test involves the compaction of a potential road-building material into a ... Read more
Use of a sedimentological technique for assessing the engineering performance of sands in roads

Author: Paige-Green, P ; Pinard, M Date: Jul 2011 Although sands cover vast areas of southern Africa, their use as road materials in an untreated state has been generally avoided. An investigation into the properties of various sands has indicated, however, that they can be used as subbase ... Read more
