Recycling and soil stabilization has been a preferable method of constructing rural roads in Malaysia for the past 5 years. Many road authorities including Public Works Department of Malaysia (PWD) and Ministry of Rural Development has used this method for constructing rural roads as it is much simpler in operation, cost effective and offer better options for rural roads development. The stabilization method has venture into another level as more and more stabilizing agents were introduced as alternative to existing and typical stabilizing agent. More manufacturers had introduced new types of stabilizing agent and also some of them are additives to the existing stabilizing agent. These new products claimed that their mixes are cost effective, easy to be carry out, and produced more durable and long lasting performance compared to conventional stabilizing agents. PWD through Road Branch had the opportunity to carry out test site to compare the performance of these new stabilizing agents. The proposal was to put 4 new types of stabilizing agents at the same road, next section to each other and performance will be monitor for a period of time. The idea was, using the same road, with same condition, same traffic load, at certain period of time, these products could show some evidence of performance within the same conditions. Besides actual performance, construction cost is also can be evaluate. With this study, PWD had the opportunity to gain more knowledge on soil stabilizer products on the market and also evaluate the most cost effective of soil stabilizer at this date. Besides that, there will be new variety of pavement design and mix design expected to be obtain from this study.
