For our common knowledge..... and to save those we love.....Dear TV3 and The Star, I am a frequent user of our North-South Expressway and I have this IMPORTANTexperience to highlight and share:- I was driving back to Penang yesterday afternoon (24 June 08) when I saw theunfortunate accident in the opposite direction involving the passenger busthat skidded and overturned at Tanjung Malim. I didn't know that the skiddedbus was from hometown Penang untill I watched TV3 news later in the eveningand was shocked to learn that the accident took two lives. Now, this is what I need to share:- I am a building contractor with over twenty years of experience and I havebeen driving my 5 series BMW (latest generation and a dammed solid roadholding car) each time I travelled to KL. Lately, the new extended 3 lanes highway had been openedup for use and since then, I have also been using it quite oftenly. HOWEVER, when I used it each time it is WET, I can really 'feel' that thenew road surface is extremely SLIPPERY! To share with some of you, my carcomes with a built-in traction control mechanism (skidding preventionmechanism) and you can feel it each time it is activated. Previously, Idon't come across this kind of slippery feel except when I drive over apaddle of water at certain speed. From my observation as a building contractor, the 'wearing course' of thenew road surface could be TOO FINE OR TOO SMOOTH and TOTALLY UNSUITABLE forhighway use! The wearing course (top premix layer) mix design for highways should be ofminimum 20mm coarse aggregate mix that will give us the required bondbetween the surface and our tyres. Fine wearing course (14mm coarseaggregate size and below) is only suitable for normal road. (A proper testneed to be carried out to determine the mix design of the wearing course). Since the opening of the three lanes highway, I had seen cars skidding infront me or in the opposite direction and approximately 2 weeks ago, one ofmy friends who is also a frequent user of our NSE, came to share with meabout his slippery feeling as well as the many skidded cars he had seenlately. I am highlighting this to TV3 and The Star with the hope that a thouroughinvestigation could be carried out immediately to find out how or whatcauses the bus to skid. A proper and independent test need to be carried outurgently to determine the design mix of the wearing course. THIS CAN SAVELIVES. FOR THOSE BCC RECIPIENTS, PLEASE SHARE THIS WITH ALL YOUR FRIENDS. IF YOU ARE USING THE NEW LANES AND IF IT IS WET, MAKE SURE YOU DRIVESLOWLY!!!! :listen:Regards, Jensen Yeoh 012-4826163 Penang.
