14th year in the profession now..
Have you seen the pavement all the way from Tarnol phattak to taxila, I overlooked it, as I was involved in the concrete work by providing high strength low W/C mix concrete additives. Khalid Rauf who was contractor.. One of the worst contractor I dealt with..
BTW. The expert on pavement design in NHA was Dr Shahab Khanzada. One of the best people out there. I m not sure if he is still there
