SYNOPSIS
Global warming that leads to the extreme weather condition is becoming critical to the environment. The vast development expediting the depletion of our natural resources, and this could accelerate the reverse impact of the environmental issues. Conservation by reuse, recycle and reduce are the solutions to address these issues.
In Malaysia, Reuse and recycle of the old asphalt and granular material into Cold In-place Pavement Recycling Pavement (CIPR) is not new. The industry has been using this concept in many different innovative ways. The recycle concept namely Cold In-place Pavement Recycle (CIPR) using Ordinary Portland Cement (cement) method prevailed in Malaysian road maintenance with large scale of application in many of the Highway, Expressway, Federal and State Road maintenance projects. This technology has been widely capitalised in many of the road maintenance programs exhibiting good performances.
The cement bound CIPR concept used in the Pavement Maintenance Work has been introduced for a long period of time in Malaysia. Combined both the good quality of Recycle Asphalt Pavement (RAP), road base materials and cement that were easily available in the Malaysian Road Pavement, a good quality of cement bound CIPR is easily implemented and proven to be successful. Many promising track records has been recorded and published.
A new technology in constructing CIPR with better efficiency and quality is currently introduced. This new technology is now made available with a flexible paving width up to 3.2m or 3.5m or 3.8m working width pending to the construction needs. This means the pavement rehabilitation work can be done in one single operational process instead of two passes traditionally. Current CIPR practices were mainly using the up-cutting concept, but the newly introduced CIPR method using Wirtgen CR machine is able to work at a down cutting mode. This means a compressive force is applied to break the existing lump of RAP more efficiently with larger content of single granular aggregate being generated. The compressive breaking effort generates a better continuity of gradation line for the road base materials that enhances the mixing of water and bonding agent with the granular materials. As such the recycled road base materials expected to gain a better compaction quality due to the improved workability.
In addition, a new cement spreading concept by incorporating a confined space cement spreading unit into a recycle machine is currently made available. A concept called “S pack” CIPR Recycler is produced to distribute the right quantity of cement and water into the mixing chamber of the CIPR machine. This method reduces the intensity of air-bond cement particle during the cement spreading process and it provides a much healthier working surrounding at the work site. Combined all the above capabilities, the CIPR concept is indeed a technology that improves the productivity and quality of Road-base Rehabilitation.
This One Day Seminar will cover the Pavement Fundamental, Bound and Unbound Road Base Technologies, Work Plan and Procedure in CIPR Construction and The Suitable Construction Equipment such as the latest Wirtgen WR 250 S Pack and Wirtgen W240/380 CR.
In view of that the organizing committee has invited Ir. Pok Sum Loong of Wirtgen Malaysia, to present the information in the respective topic. This One Day Seminar on CIPR for Road Work definitely bring enormous knowledge and value to the road industry.
