...B. Kermani; S. M. Stoffels; M. Xiao Pumping in rigid pavements is defined as the migration of subgrade soil into the overlying layers, redistribution of materials under the slabs, and ejection of materials through joints. Pumping can compromise pavement performance. This study evaluated geotextiles...

...I. Alobaidi; D.J. Hoare Research into the mechanisms of pumping of fines at the subgrade-subbase interface of highway pavements is presented and discussed with respect to the behaviour of the subgrade-subbase system without a geotextile/transition layer and with a geotextile/transition layer...

...I. Alobaidi; D. Hoare This paper presents the results of a laboratory study using a Unit Cell Test and a modified 100 mm Triaxial Pumping Test. The effects of some of the factors affecting the pumping phenomenon are presented and discussed. A relationship between the amount of pumping...
