Influence of rainfall on quality of service at multilane roundabouts and its time headway implications.
(2018)Roundabouts, or traffic circles as they are often called in South Africa, are priority intersections with a unique yield rule. Drivers approaching the roundabout must give way to those that are already circulating the ... -
Influence of the degree of waste pre-treatment on carbon emissions' production and nature.
(2007)This study was carried out to gain knowledge of the degradation processes in an anaerobic environment of pre-treated waste for different degrees of pre-treatment and the evolution of waste pre-treatment by forced aeration. ... -
An investigation into adopting different piling systems for integral abutment bridges.
(2016)In recent years the use of integral abutment bridges has become increasingly popular, globally. These bridges have many advantages because the super-structure and sub-structure are monolithic in nature, no bearings and ... -
