The usage of cement for soil stabilisation in construction of low volume roads in Malaysia

摘要

There are about 25% of the total road networks in Malaysia is an unpaved road which is contained gravel or earth road [1].These are commonly referred to as the low volume roads or unpaved rural road or agriculture roads which required a very minimum standard of design and construction due the low traffic impact and function of the road as an accessibility tool to the local communities.Difficulties in transporting of the materials to the construction site due to the distance from the quarry or construction material source do occur together with the requirement of suitable machinery.Soil stabilisation was identified as an alternative method to facilitate the design and construction requirement in achieving the implementation of the project where respect to cost,time and quality.Currently,soil stabilisation method was not popular in Malaysian construction industry players especially among road designer because the conventional method of pavement design always been the most priorities.Perhaps this may due to the absence of the specification purposely for soil stabilisation works.This paper will present the Malaysian experiences of implementing cement as soil stabiliser in road construction project for rural and low volume roads.The study had been conducted in the road construction project of Jalan Pos Sinderut,Kuala Lipis,Pahang.The scope of the study covers all the stages that involved in the implementation of soil stabilisation using cement this project including design,procurement,and construction.
