Manuals
Twenty
seven technical manuals have been produced by Sabita, covering the
selection, handling and use of bituminous materials in a wide range of
applications.
These manuals are supplied at a nominal charge to
Sabita members. To the wider public, the manuals are available at a
higher cost to cover the printing, distribution and administration
costs.
Prices are inclusive of VAT, but excludes handling
and postage outside of the Republic of South Africa.
On 22 July 2010, Sabita council reversed
its 2006 decision which made those manuals freely available, in
electronic format, to all visiting the Sabita web site. These are now
only available as a free download from the Sabita members website.

Keywords: hot-mix asphalt manufacture construction
Covers correct techniques, procedures and plant requirements employed
in the control of component materials, mixing, storage, transport, paving
and compaction of all types of hot mix asphalt currently in use in southern
Africa.
Keywords: economics surface treatment
The package has been developed using Excel spreadsheets as a simple
mechanism for carrying out cost comparisons between maintaining an existing
unpaved road and improving it by using various upgrading options. The
improvements generally relate to low-cost seals on in situ or local
materials, but also include dust-palliative options to allow direct
cost comparisons. A CD containing the SuperSurf programme is included
in the package.
Keywords: bitumen handling safety
The scope of this manual on health, safety and environmental aspects,
which replaces Sabita's Manual 8 - Bitumen Safety Handbook, has been
updated in accordance with current legislation and extended to incorporate
international best practice in repsect of work safety and health, as
well as environmental conservation.
Keywords: construction surface treatment
Applicable to both rural and urban situations, this guideline provides
justifications for bituminous surfacings and the selection of the most
suitable surfacings for temperary deviations, particularly in situations
where a cost analysis would not be appropriate or possible. Factors
considered include traffic volume, duration and length of the deviation,
and the surfacing life and costs.
Keywords: economics standards application
This manual covers the choice of appropriate bituminous surfacings for
low volume roads, analysing various conditions and performance requirements.
Easy to use graphs are provided to assist in the choice of bitumen or
gravel surfacings, and these have been developed from economic and financial
cost analysis. A method is provided to determine the life-cycle costs
of alternative surfacing choices.
Keywords: labour intensive construction
A guideline on the choice of bituminous surfacings for labour enhanced
construction, criteria for selecting the surfacing to meet the objectives
of job creation, to maximise the labour component, or to transfer skills.
Discussion includes social issues, feasibility, organisation of contracts,
productivity and implementation.
Keywords: labour intensive construction
A complement to Manual 11 (see above), this publication is intended
for use by contractors’ staff in the planning of labour enhanced construction
and in the training of workers. Activities described include, inter
alia, preparation of the basecourse surface, spreading of aggregates,
mixing and application of slurry and compaction. The maintenance section
covers base and surface repair, pothole and edge repairs, crack sealing,
slurry seals and cold asphalt preparation.
Keywords: hot-mix asphalt design application
The result of Sabita’s research into the design and performance of Heavy
Duty Asphalt Pavements (HDAPs), this manual examines general considerations
in the design of LAMBS, provides a detailed description of mix design
methods and guidelines on the interpretation of test results, constructibility
and quality control, cost considerations and a case study.
Keywords: bitumen stabilisation emulsion
With emphasis on the upgrading of substandard materials, this manual
provides guidelines on the use of bitumen treated granular materials
and includes design considerations, mix design using both the stabilisation
design approach and the modification design approach, guidelines on
design and construction, quality control and economic considerations.
Keywords: hot-mix asphalt design noise
Porous asphalt mixes - design and use: Guidelines on the design of porous
asphalt, mix design method and interpretation of test results, the constructability,
quality control and maintenance of porous asphalt, a practical illustration
of the mix design method through a case study, and an overview of performance
under accelerated trafficking.
Keywords: sand asphalt standards
Covers the mix ingredients of sand asphalt and sand selection criteria,
looks at manufacture, construction, performance, applications and specifications,
and analyses test methods, cost effectiveness and quality control.
Keywords: bitumen modified wearing course standards
The guidelines cover the design, manufacture, handling and construction
of bitumen rubber asphalt. It deals primarily with those aspects of
hot mix asphalt that are specific to bitumen rubber asphalt and should
be read in conjunction with Sabita Manual 5 to obtain a comprehensive
perspective of the processes involved.
Keywords: cracking maintenance
With specific emphasis on modified bituminous binders, this draft technical
guideline provides practitioners with recommendations for the treatment
of active cracks in road pavements. While no design methods are recommended
or described, the recommendations given serve to add to the existing
design methods, especially those for surfacing seals. Topics include
crack types, visual surveys on cracked pavements, crack movements, methods
of sealing individual cracks, surfacing seals using modified binders
and some cost considerations.
Keywords: bitumen stabilisation emulsion design
application
As a complement to Manual 14 (see above) this document covers the design
and construction of base course materials using a low percentage of
bitumen emulsion, whereby the properties of the raw material – typically
natural gravel – are enhanced by increasing its capacity to withstand
shear stresses.
Keywords: hot-mix asphalt construction compaction
climate
Most current specifications do not adequately deal with the complexity
of laying hot-mix asphalt in adverse weather conditions. This guideline
examines major areas of risk and concern when hot-mix paving in rain,
wind and low temperatures. Recommendations are provided on procedures
to promote efficiency and reduce risk without compromising a sound end
result, and on prime, tack and bitumen mixing temperatures, managing
the effects of rain, minimum base, air and lay-down temperatures, compaction
management and techniques for assessing overall risk.
Keywords: hot-mix asphalt design application
Developed to assist the design of hot mix layers to incorporate the
principles and recommendations embodied in the Interim guidelines for
the design of hot mix asphalt in South Africa (IGHMA), which is currently
being validated through a series of projects scheduled for completion
in 2010. The guide is not a replacement of the IGHMA rather it should
be considered a support document underlining some of the content, pointing
out pitfalls or gaps and referring to supplementary materials to ensure
cost-effective design.
Keywords: bitumen handling
Developed to ensure the quality of bituminous binders during the handling
of the product as a raw material, i.e. before use in the final product
and includes loading, transportation, offloading, testing and sampling
practices. These handling activities generally occur when penetration
or cutback bitumen is transported from the refinery to a construction
site or asphalt plant or depot or binder factory fur further processing
and when modified binders or bitumen emulsions are transported from
the factory to the construction site, asphalt plant or depot.
Keywords: prime precoat bituminous
Although the use of coal tar for priming granular bases and precoating
surfacing aggregates has been common practice in South Africa, global
best practice now dictates the discontinuation of these binders for
reasons of protecting worker health and environmental conservation.
The purpose of this guideline is to assist road authorities with the
selection of proven alternative products and processes that have been
used successfully. While coal tar has been used in a variety of road
construction applications over many decades, this document focuses only
on priming granular bases and precoating surfacing stone.
Keywords: asphalt surfacing thin layers
The purpose of this manual is to present a set of general guidelines
to assist clients, consultants, paving contractors and asphalt manufacturers
to design, construct and manage the quality of thin hot mix asphalt
wearing course layers on roads carrying light (predominantly passenger
car) traffic, mostly in residential areas.
