Why are Pattaya’s Roads so Bad?

Why Are Pattaya – click through the following website page – ‘s Roads So Bad? Being a local expat you would sometimes ask yourself when driving up Theppraya Road, “How long have they been working on this road for?” I estimate that road has been under construction now for around four years. Gavin Perfect of Global Design & Build Co,. I was amazed to see a TV report not so long ago showing cars and bike trying aimlessly to drive through 2 feet of water after a small rain shower. One section of the road was partially completed in Jomtien over the Christmas holiday periods, being the area behind the Immigration office. Ask yourself the question, why does it take so long to complete a relatively easy road construction? Why is it that in just a few months the road is completely damaged again? The answers to solve these problems are clear to see during the construction process. Like any road in the world the most important part of road construction is the sub foundations.

"Tim Boutique Hotel"These are the materials and base foundation that the road finishing is laid on. The procedure to comply to also isn’t implemented in Thailand road construction. When constructing a heavily trafficked road the first objective is to excavate to a good sub virgin (or compact) sub soil. Once complete the sub base should be installed in layers of a specified maximum depth along with special membrane materials, and compacted to a specified strength, which is then tested using a compaction gauge. To make sure this sub – base is constructed correctly you require specific machinery that they simply do not use here in Thailand. Now this is where many of the problems arise here in Pattaya – https://pattaya.thaibounty.com/2022/03/31/u-tapao-airport-pattaya/ – . Before completing the sub base to finished height (ie the final layer) you would then install all underground services, being drainage, cable ducts (Thailand seems to not want these). Once any services are laid in place the void should be filled using a graded material and compacted to a specified target.

Four Seasons PlaceThis simply isn’t done here and hence once the rains come the underground voids fill and subsidence occurs, meaning the road surface becomes under mined which creates all the pot holes we see and the breakdown of the road finishing surfaces. You will notice that many of the local roads are of two different types of surface, some being Tarmacadem (Tarmac) and others concrete. In many cases the reason for installing one over the other potentially comes down to cost. My personal opinion for a country such as Thailand would be to use concrete. My reason for this is due to the climate, with tarmac decomposing quicker in high temperatures. Both road surfaces hold their own advantages and disadvantages. Concrete roads are easier to repair, but in hand cost more in labour to install and take longer to install. Tarmac can handle traffic just hours after installation. Another major problem is the drain locations. I’m still amazed that the Civil Engineers designing and constructing the local roads seem to think that water travels up hill.

They place the drainage covers in the middle of the road as opposed to up against the kerb line and have the gradient of the road fall towards to drain covers. Many times when we see this is due to the road being widened after the original road had been constructed, but a simple solution is to create off set drainage at the road side kerb lines. Many of these over looked solutions may come down to expense, but in the long run, and like in most situations, trying to cut corners in the beginning lead to higher expense in the long term. Road maintenance can be a huge expensive for any local council, so to save money the job should be done properly in the first place. Most of the problems with drainage and flooding in Pattaya cannot be helped. A large section of the city ground levels are very close to the water table, or sea level, and most of the original infrastructure put in place when this was a quiet holiday town aren’t sufficient to cope with what the city is today.
