‘Construction and design of a 50m single span uhp ductile concrete composite road bridge’
A single span 50m long prestressed road bridge has been fabricated under a Public Works Department contract in the State of Negeri Sembilan, Malaysia. The bridge, across a river, was constructed at the small village of Kampung Linsum, Sungai Linggi. To date, this bridge is the first in Malaysia and may also be the world's longest composite road bridge made from ultra-high performance ductile concrete (UHPdC). This paper presents the features of the UHPdC precast girder; gives a brief insight into the manufacturing process of the girder; highlights the bridge's construction sequence; illustrates the design method and provides an environmental impact calculation. The midspan deflections of the bridge at different times in its construction history were compared against the collected field data and these figures showed that the calculated values were in general in agreement with the field data.
9th July 2012, the people of Kampung Seberang now have a reason to rejoice as a new bridge will be build for them, to connect to the mainland, Kuala Sepetang after 30 years of waiting. The long awaited bridge measuring at 110m and 3m wide will serve as the main connecting access for the 200 families in the island to go in and out of the place to the mainland safely. The people here, including school children had been using the service of a small motor powered boat as the main transport to get to the mainland across the 80m wide Sungai Reba.
On 28th June, the Ulu Chemor bridge girders were successfully launched on to the RC abutment using a single unit 275 tonnes capacity mobile crane (DEMAG brand). Accroding to the professional beam launcher, the DURA beams (i.e. TBG1325) are easy to lift due to its lightness and stiff characteristics. The lifted beams have a total length of 29.5m and weight up to 31 tonnes, as compare to conventional prestress RC beam, the RC beam would has weighted up to 60 tonnes per piece for the similar length.
4 June 2012, the “Mesyuarat Pegawai Pegawai Kanan JKR Malaysia” took place in Bayview Hotel, Langkawi, Kedah Darul Aman this year was officiated by YB. Dato’ Seri Shaziman b. Abu Mansor, Minister of the Ministry of Works Malaysia. This event which is held annually in different part of the country, brings together some 400 top management officers from all parts of the nation including Sabah and Sarawak.
YAB Dato' Seri Utama Hj Mohamad Bin Hj Hasan Ground Breaking For Construction of The New Rantau-Siliau Bridge Project, Seremban District, Negeri Sembilan.
Dura Technology Sdn Bhd is yet to set another new national record with this “51m single span motorway bridge” in Jalan Rantau-Siliau, Seremban. This is the third bridge of UHPdC in this state. The ground breaking ceremony is officiated by Menteri Besar Negeri Sembilan YAB Dato' Seri Utama Hj Mohamad B. Hj Hasan on 24th May 2012 alongside with JKR Negeri Sembilan Director Dato’ Ir Dr Roslan. The event took place at the bridge construction site that sees around 250 guests.
