  • Donaldson, GW; Billingham, PA (1973)
    The words ‘built on a firm foundation' have become part of the language and most people would unhesitatingly agree that a house has to have a foundation' without perhaps understanding exactly why. If one were to place an ...
  • Jobson, AJ (CSIR, 1973)
    A number of rumble installations have been constructed on rural roads in South Africa and although no local accident data are available the provincial roads engineers consider them of value in alerting drives to the need ...
  • Ferreira, T.M; Billingham, P.A (1973)
    The difference between sound and noise varies from one human being to another. Noise, then, is simply unwanted sound and to understand how it can be combatted we must know more about its nature. A guide of acceptable levels ...
  • Lotz, F.J; Billingham, P.A (NBRI/CSIR, 1974)
    Too many people need to switch on the air-conditioning every time the sun comes up and light a fire as soon as it does down again. The sun is a wonderful source of energy that comes free of charge to all of us.
  • Grobbelaar, C.S; Billinggum, P.A (NBRI/CSIR, 1975)
    The most basic function of a building is to protect its occupants and their possessions from the weather. It is no wonder therefore that a leaking root, or finishes marred by dump, leave the owner feeling cheated- his ...
  • Cawood, WN (NBRI/CSIR, 1976)
    Since primitive man first set fire to a heap of twigs to warm his cave, mankind has been making use of the earth's energy resources. Fortunately, we still have the sun, which offers us an inexhaustible source of non-polluting ...
  • National Institute for Transport and Road Research; Transport and Road Digest (CSIR, 1977)
    Rumble surfaces are intermittent short lengths of coarse-textured road surfacings on which vehicle tyres produce a rumbling sound. used in conjunction with appropriate roadsigns and markings, they can reduce accidents on ...
  • Booth, AR (1977)
    Research into collapse settlement in compacted soils is described, with special reference to recent cases in Southern Africa where collapse settlement occurred in road embankments following wetting of the soil. The laboratory ...
  • Billingham, PA (NBRI/CSIR, 1977)
    When man first began to build shelters for himself about 800 years ago he concentrated on providing effective walls and roof. The floor go-t scant attention because it was already provided by the earth. The first soft ...
  • Billingham, P.A (NBRI/CSIR, 1977)
    It has become fashionable to talk of 'energy crisis' but in fact there is still no shortage of energy - if one is prepared to pay the price. This situation, however, cannot continue indefinitely because our limited supplies ...
  • Mitchell, MF; Semmelink, CJ; McQueen, AL (National Institute for Transport and Road Research: CSIR, 1977-06)
    For some time road engineers have been concerned that the variability inherent in road construction materials and their sampling and testing has not been logically and consistently catered for in the road construction ...
  • Long, K (NBRI/CSIR, 1978)
    Thatch has been used as a roofing material from the earliest times. The basic tools of the thatcher's craft have not changed over hundreds of years. Thatching is a craft that is traditionally handed down from father to son.
  • Stewart, TJ; Ittmann, HW (Palgrave Macmillan, 1979)
    A study of the economic distribution of maize throughout South Africa is reported. Although the problem of minimizing total transportation costs in such a situation is a classical one, and its solution is well known, there ...
  • Ferreira, T (NBRI/CSIR, 1979)
    Home owners often complain that traffic noise disturbs their indoor peace and quiet. It is difficult, expensive and probably unnecessary to make the whole house soundproof. To appreciate and apply the practical tips that ...
  • Weinert, HH (CSIR, 1980)
    Naturally occurring materials, such as rock and soil, constitute a significant portion of the materials content and cost of a road. Most textbooks dealing with road construction materials, however, are mainly concerned ...
  • Addis, B.J (NBRI/CSIR, 1980)
    Paving is used to cover ground to eliminate dust, mud or erosion and to facilitate the movement of traffic. It can also be used to control the moisture content of the underlying soil around houses built on unsable soil ...
  • Page-Shipp, RJ (CSIR, National Building Research Institute, 1980-09-10)
    This article correctly reflects the principles of Solar Water Heating as they pertain to South African conditions. However, it was written in 1980 and the global energy situation has changed considerably. Furthermore, ...
  • Viljoen, AW (Pavement Engineering, National Institute for Transport and Road Research, CSIR, 1982-06)
    Pavement behaviour under the super single tyre (SST) was investigated and compared with that under a conventional dual tyre (CDT). Contact areas and contact pressures over a range of loading conditions were measured and ...
  • Netterberg, F; Paige-Green, P (Soil Engineering Group and National Institute for Transport and Road Research, 1984-04)
    The problem of deterioration of lime, lime-slag and cement stabilized pavement layers during curing, before sealing and in service is partly ascribed to carbonation of the stabilizer during curing and subsequent exposure ...
  • Cromarty, R.E; Billingham, P.A (NBRI/CSIR, 1985)
    Thousands of years ago primitive man made use of some of the colourful materials that he found around him to stain his body and clothing. He also decorated the walls of his cave with pictures of hunters and wild animals ...
