Foreword

D1 SPJ Sec 4-Part 1.pdf
As practices in road construction change over time, it is imperative for Jabatan Kerja 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 to help in improving the quality of constructed product. In unison, 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 infrastructure 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 o f road related products.

This document "Section 4: Flexible Pavement" 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 was vetted through by a group of independent consultants and presented at various workshops. Feedbacks and comments received were carefully considered and incorporated in the specification where appropriate.

Standard Specification for Road Works - Section 4: Flexible Pavement consists of two (2) parts namely "Standard Specification" and "Specialty Mix and Surface Treatment". The part on "Specialty Mix and Surface Treatment" is entirely new.
