This thesis presents a catalogue of designs for segmental block
pavements for use in Southern Africa. It developes a basis for the
designs by identifying and quantifying those parameters which affect
the design. The evolution of the designs and the experimentation
promoting their formulation are described.
Chapter one details the motivation for the thesis. Here it is initially
established that there has been little research done around the
world in substantiating the design guides published principally by
manufacturers. A brief historical review shows that types of segmental
block paving such as setts and stone blocks have been used for
many hundreds of years but no scientific basis for their design was
found. The fundamental design of all pavements requires effective
compaction of the various layers and adequate drainage.
Pioneers in the development of materials suitable for pavement construction
used tars and bitumens to seal the structural layers of a
pavement from the ingress of moisture to ensure optimum performance,
whilst construction techniques demanded drainage around the pavement
to keep it substantially dry. |

Hierdie proefskrif bevat 'n katalogus van ontwerpe vir Steenplaveisels
vir gebruik in Suider-Afrika. Hierin word 'n basis vir die ontwerpe,
deur die hoeveelheid parameters wat die antwerp beinvloed te identifiseer
en te bepaal, ontwikkel. Die ontwikkeling en die eksperimente
wat die formulering van die ontwerpe bewerkstellig het 1 word beskryf.
In Hoofstuk een word die motivering vir die proefskrif gegee. Daar is
vasgestel dat daar in die wereld weinig navorsing gedoen is om die
riglyne vir ontwerpe wat hoofsaaklik deur Vervaardigers gepubliseer is
te staaf. Met 'n kort historiese oorsig is gevind dat sekere steenplaveisels
soos "Selfts" en "Stene" al vir honderde jare gebruik \'lord
maar geen wetenskaplike basis vir hulle antwerp kon gevind word nie.
Die grondontwerp van alle plaveisels vereis effektiewe kornpa.ksie en
dreinering van al die lae.
Pioniers in die ontwikkeling van geskikte materiale vir padkonstruksie
het tere en bitumens gebruik om die struktuurlae van 'n plaveisel teen
die indringing van nattigheid te seiH 1 om sodoende optimum werkverrigting
te verseker 1 terwyl konstruksie tegnieke gesorg het vir doeltreffende
dreinering langs die plaveisel om dit in 'n aansienlike mate
droog te hou. |
