• Falling Weight Deflectometer (DWD)
• Asphalt Coring
• Typical Core Log
• Dynamic Cone Penetrometer Test (FWD)
• DCP Test Plot
• Trial Pit
• Manual Surface Condition Survey (SCS)
• Ikram Road Scanner
• Traffic & Axle Load Survey
• Material Testing -
Polymer Modified Asphaltic Concrete (PMA) Launching at Bentong
Roadcare (M) Sdn Bhd makes a history again during the 9 establishment year when appointed as major concession company for construction project and road maintenance using products Polymer Modified Asphaltic Concrete (PMA).
PMA consumption of product will be implicated route in FT08 Jalan Bentong – Raub (Section 7.635 – 10.000), FT02 Jalan Karak – Temerloh (Seksyen 185.10 – 186.580) and FT68 Jalan Bentong – K.Mud (Seksyen 72.230 – 73.830). PMA launching ceremony was perfected by Works Minister, Dato’ Shaziman Abu Mansor in Padang Tras, Bentong, on 21st of June 2010.
In the opening speech, Dato’ Shaziman said, Public Works Ministry (KKR) had arranged strategy and planning to increase quality of roads in Malaysia and to support the desire, National Economic Action Council in Rancangan Malaysia 10th had agreed so that concrete cement render as much as using 5 percent for road project new.
He said, concrete cement render have many advantages compared pavement conventionally especially from longer life range aspect, ‘life cycle cost‘ lower and can accommodate higher axle burden.
As many as more 500 invitation present to enliven ceremony which started at 10 o’clock in the morning. Present also in the ceremony is Roadcare Managing Director (M) Sdn Bhd, Dato’ Hasnur Rabia’in Ismail, Health Minister, Datuk Seri Liow Tiong Lai who is also Bentong Member of Parliament and Committee Chairman Tempatan Government, Environment and Kesihatan State, Datuk Hoh Kai Mun.

CIPR
Written by RAZMAN BIN ABDULLAH
Conference Room, HCM HQ. On Wednesday: March 31, 2010, En. Mohamed Napi Yunus conducted a K Sharing Session on CIPR. By way of introduction, En. Napi works for Malaysian Recycling Company abbreviated as MARECO within the HCM Group of Companies. He has tremendous amount of experience in Road Design, Engineering and Construction, as such CIPR is very much his area of expertise. He is also the Knowledge Advsior for the Community of Recycling Technology (CORT) Community of Practice (COP) who was gracious enough the spend time with us to impart knowledge.
CIPR is one of the many solutions which our company employs in road repair works. It is an environmentally friendly and cost effective alternative to partial or total reconstruction of cracked pavements. Historically, the first CIPR job that was undertaken in our country was a road length of 8km between Temerloh and Mentakab, Pahang of which it was a joint venture effort between both University Malaya and Jabatan Kerja Raya.
CIPR is a good solution in treating major distress roads such as severe crocodile cracks, rutting or deformation, and pumping. The advantages to CIPR are the following:• Faster and more efficient as minimal excavation and dump trucks required
• Reuse of existing materials, and reduces new construction materials and transport cost
• The technique can give equivalent pavement structure condition and cost saving compared to conventional method
• Increases the shear strength and reduces the moisture susceptibility of granular materials
• Flexible and fatigue resistant (Foamed Bitumen and Emulsion)
• Cost Savings with approximately 10% – 30 %Some of the ingredients which makes up a typical CIPR solution would require Premix, Foam, Cement, and Crusher Run Furthermore a typical costing of any CIPR project works in the areas of Machinery, Manpower, and Material would entail the following :
Machinery :
Recycling Machine, Water Tanker, Vib Roller, 3 Tonne Lorry, Van / 1 Tonne Lorry, Back Hoe, Back Pusher/Power Broom, Paver Seat, T.Coat and P.Coat Spray, and Motorgrader.
Manpower :
Project Manager, Site Engineer, Site Supervisor, Scissorman, General Workers (Premix), General Worker (Cement) and Accommodation (Traffic)Material/Other Cost :
Cement, Premix ACBC, ACWC, Diesel, Prim Coat, Tack Coat and ToolsThis K Sharing Session was attended by HCME, Roadcare, and KPS HCM business units which cuts across departments such as MARECO, QA Contracts, MIS, SFU, and Engineering. It was indeed a remarkable session in which knowledge transfer was accelerated between several business units in a single room, in a mater of 2 hours.
We hope that this type of K Sharing Session amongst the many K Solutions which the other 17 Community of Practice (COP) have committed in their 2010 Calendar Plan will enable HCM Group of Companies to reach the Knowledge Based Organisation in 2011 (KBO 2011) target as envisaged by our MD/CKO , YBhg Dato’Ir Hasnur Rabian Ismail.

HIPR
Rabu, 20 Mei 2010: Pada hari Rabu, 19 Oktober yang lalu, Teknikal COP (Community of Practice) telah mengadakan satu sessi K-Sharing HIPR yang di kendalikan oleh En. Napi Mohamed Yunus. Pihak Teknikal COP telah memilih En. Napi kerana beliau mempuyai pengalaman dan pengetahuan yang luas dalam penyelengaraan HIPR (Hot in-Place Recycling).
Program ini dibuat bertujuan untuk menambahkan lagi pengetahuan kepada ahli COP berkenaan HIPR. Melalui teknik pengunaan semula HIPR ianya dapat membantu pihak yang terlibat bagi menjalankan proses penyelengaraan turapan jalan dengan sempurna. Penggunaan kaedah ini dapat membantu syarikat serta menjimatkan kos, masa dan juga tenaga. Selain itu juga kaedah ini dapat membantu pihak pekerja menjalankan kerja dengan lebih mudah dan cepat.
Banyak lagi kelebihan penggunaan proses HIPR ini contohnya dari segi alam sekitar kerana penggunaannya mengunakankan turapan yang sedia ada, kekuatan struktur yang lebih baik dan masa pembinaan yang singkat.
