Thursday, 5 July 2018, Kuching: A one day seminar to explore the use of recycling pavements in road building is being held here today attended by all main contractors of the 11 works packages of Pan Borneo Highway Sarawak.
Jointly organised by Lebuhraya Borneo Utara Sdn Bhd (LBU), Cahya Mata Sarawak Berhad and Wirtgen Group in collaboration with Institution of Engineers Malaysia (IEM) Sarawak chapter, the seminar on Cold In Place Recycling (CIPR) Pavement Technology is being attended about 170 participants.
Apart from contractors and consultants, representatives from the State Public Works Department (JKRS) and other road agencies and companies from Peninsular Malaysia and even from Myanmar are also attending.
CIPR has proven to be a successful solution for road maintenance around the world, including in Sarawak. It can be implemented via in-place and in-plant methods with various options of binding additives such as Ordinary Portland Cement (OPC), Bituminous Emulsion and Foam Bitumen.
LBU chief executive officer, Ir. Safuani Abdul Hamid, in his brief address to the participants, said the seminar was organised as part of the Company’s knowledge-sharing efforts.
He shared with those present on the details of Pan Borneo Highway Sarawak which spans from Telok Melano to Miri under the Phase One of the Project; with Limbang and Lawas being the final connectivity point to the Sabah border under the Phase Two of the Project.
“While most of the Pan Borneo Highway Sarawak is being developed, there are about 120km of existing 4-lane dual carriageways and overtaking lanes which were constructed much earlier.”
“This CIPR technology is a good alternative to upgrading these existing stretches to match and standardise the quality to that of the new stretches which we are developing as Pan Borneo Highway Sarawak,” said Ir Safuani.
Meanwhile, managing director of Wirtgen Malaysia, Ir. Pok Sum Loong, in his introduction session shared with the participants on the CIPR concept and technology during the seminar.
Other speakers at the seminar included Professor Kim Jenkins who shared his knowledge on flexible pavement and material behaviour under load, as well as project examples which incorporated the CIPR stabilised layers.
CMS Group companies CMS Pavement Tech and CMS Roads shared their Sarawak roads experiences using CIPR technology, specifically on implementation and durability of the recycled pavements over the years.
