2 FOREWORD As practices in road construction change over time, it is imperative for Jabatan Ketja Raya (JKR) to continuously update and improve their standard specifications. These new specifications are not only aimed at keeping abreast with current technologies but also helping in improving the quality of constructed product. In uriison) these new specifications have a significant positive impact on the construction industry especially with the incorporation of new products and technologies. Standard Specification for Road Works is an essential component in the road inti astructure construction industry. This specification provides an improved guidance in the material selection and the production of good quality workmanship and products, based on current best practices. The purpose of this standard specification is to establish uniformity in road works to be used by road designers, road authorities, manufacturers and suppliers of road related products. This document "Standard Specification for Road Works- Section 8: Traffic Signal System" is a part of a series of improved specifications in the Standard Specification for Road Works. The compilation of this document was carried out through many discussions by the technical committee members. Additionally it has been reviewed by a group of independent consultants and presented at a technical workshop held on July Feedbacks and comments received were carefully considered and incorporated in the specification where appropriate.
