All you frequent users of the North-South Expressway

Be more cautious when driving on the third lane.

 

North-south highway 3rd lanes

 

I am a frequent user of our North-South Expressway and I have this IMPORTANT experience to highlight and share:-

I am a building contractor based in Penang with over twenty years of experience and I have been driving my 5 series BMW (latest generation and a dammed solid road-holding car) each time I travelled to KL. Lately, the new extended 3 lanes highway had been opened up for use and since then, I have also been using it quite often.

 

HOWEVER, when I used it each time it is WET, I can really 'feel' that the new road surface is extremely SLIPPERY! To share with some of you, my car comes with a built-in traction control mechanism ( skidding prevention mechanism ) and you can feel it each time it is activated. Previously, I don't come across this kind of slippery feel except when I drive over a paddle of water at certain speed.

 

From my observation as a building contractor, the 'wearing course' of the new road surface could be TOO FINE OR TOO SMOOTH and TOTALLY UNSUITABLE for highway use!

 

The wearing course ( top premix layer ) mix design for highways should be of minimum 20mm coarse aggregate mix that will give us the required bond between the surface and our tyres. Fine wearing course ( 14mm coarse aggregate size and below ) is only suitable for normal road. ( A proper test need to be carried out to determine the mix design of the wearing course). Technically, this comment on the size of the coarse aggregate (or "stone" in lay language) for the wearing course (top most layer of the road) is correct in that it should not be too fine for better grip between the tyre and the road surface.

 

Since the opening of the three lanes highway, I had seen cars skidding in front me or in the opposite direction and approximately 2 weeks ago, one of my friends who is also a frequent user of our NSE, came to share with me about his slippery feeling as well as the many skidded cars he had seen lately.

I am highlighting this to TV3 and The Star with the hope that a thorough investigation could be carried out immediately to find out how or what causes the bus to skid. A proper and independent test need to be carried out urgently to determine the design mix of the wearing course.

 

THIS CAN SAVE LIVES. IF YOU ARE USING THE NEW LANES AND IF IT IS WET, MAKE SURE YOU DRIVE SLOWLY!!!!

Thanks for info,bro

[Dwoon]

Read that like 3 years ago.......

[Mk1]

110km/h limit... stick to it... =X

[BuB]

Thank You, this info does help and I am getting technical knowledge from it. Cheers

Read that like 3 years ago.......

 

 

i think older than that...

Thanks for this critical safety information.

 

My Toyota also have TC, ESP and VDIM, just came back from KL during the Sept school holiday.

Personnelly they were not activated.

maybe my driving style is Ah Peh type. mainly cruising. occasionally speed up.

 

 

Definately, agree on using correct aggregates for certain road.

 

Driving on NSHW exposes drivers and passengers to high fatal risks from high speed accidents.

 

Side track- what price range to overlay wearing course for higway? Did you install the highway fender?

 

I was thinking that I paid S$6000-S$8000 for a set of 8m curve fender ( 4 pcs curve members, 2 end caps and 5 supports). For road overlay 50mm at S$15 to $30 per sq/m.

So whoever got the contract must be making tons of $$$ to overlay install fenders for NSHW.

Many thanks for sharing this with us. I believe this to be a quarry waste disposal exercise since Lane 3 suppose to be used by heavy slower vehicles

110km/h limit... stick to it... =X

I believe only a handful drive at that speed most of the time along that NSH. Many/most seems to 'cruise' at 150km/h (high-beamed once when I drove at 120km/h) along Pasir Gudang Highway. Overtaking within presentable distance requires 180km/h to be well done (I ever met others (Singaporeans)doing 90km/h along NSH)

[5936]

To be fair, some of the locals are also guilty of cruising indifferently at slower than the stipulated speed limit.

 

No offence, but especially those poorly maintained, overloaded and underpowered car as well as big trucks.

 

watch out for these trucks, they like to sprung surpise lane change.

Really ah

 

Didn't feel it when I used those new lanes leh Maybe my Latio too light

You are right. One thing I notice, when my speedo reads 110km/hr, GPS reads only 98km/hr there abouts. So I usually drove 130km/hr meter reading, GPS shows 120 or so. Along KL ring road, most car within 120km/r meter readings. After that, its all hell break loose.

I believe the big truck-drivers lost control staying in one lane due to worn out shock-absorbers

Speedo calibrated to read a little faster as you drive faster for safety reasons. Hence the differences in speed reading on the speedo against the GPS

GPS reading is inaccurate due to timing lack.

It could also be contributed to the tyre sizes. Well.. mine comes stock anyway.

It does make some sense, but would not quite agree. Tested the timing of arrival and its quite accurate. But then again, the number of readings the unit takes per minute also plays a part.

On a two-lane road, those on the left seldom break the speed-limit law. The same for a three-lane road. Perhaps you seldom travel on the leftmost lane........ In my case, I seldom travel on the rightmost lane, except when overtaking, and still very rarely exceed the speed limit even when overtaking. That is why I am one of those who never slow down when seeing traffic police or speed cameras, because there is absolutely no need to do so, and have no speeding ticket all these years. Just that a 350 kilometer journey takes five to nine hours...................
