A Guide On Geometric Design Of Road 2

A Guide On Geometric Design Of Road

Road Engineering Association of Malaysia (REAM), through the cooperation and support of
various road authorities and engineering institutions in Malaysia; publishes a series of official
documents on STANDARD SPECIFICATIONS. GUIDELINES, MANUALS and
TECHMCAL NOTES which are related to road engineenng. The aim of such publications is
to achieve quality and consistency in road and highway construction.


The cooperating bodies are:-
public Works Department, Malaysia
Malaysian Highway Authority
Institution Of Engineers, Malaysia
Institution of Highways & Transportation (Malaysian Branch)


The production of such documents are carried out through several stages. The documents are
initially compiledjdrafted by the relevant Technical Committee and subsequently scrutinised
by the relevant Standing Committee of REAM. They are finally endorsed by road authorities
and practitioners of road engineering at a conference/workshop before publication. REAM
welcomes feedback and suggestions which can update and improve these documents.
This GUIDE ON GEOMETRIC DESIGN OF ROADS is the revision of the existing
Arahan Tekrlik (Jalan) 8/86 “A Guide on Geometric Design of Roads” published by Jabatan
Kerja Raya.


The revision was undertaken by the Standing Comrnittee on Technology and Road
Management of the Road Engineering Association of Malaysia (REAM) with the mandate
given by the Director-General of Public Works Department, Malaysia.


The draft of this Arahan Teknik was presented and discussed at the Forum on Technology
and Road Management in November 1997 and the 4th Malaysian Road Conference in
November 2000.

It is hoped that this Guide will address the shortcomings of Arahan Teknik (Jalan) 8/86 and
will accepted by the highway engineering fraterniw in the country.
