chrgrims Posted September 17, 2009 Share Posted September 17, 2009 Hi, Our property has some very soft earth on one side. This is the road to the new pool, so we need to fix it. We tried to harden the earth with a machine, but it didnt do much good (a machine that looks like a big lawn mower,flat underneath). Do we need a big road roller? Should we put concrete here, or isnt that a good option on a surface like this? Maybe gravel is better? Thanks in advance, chr Link to comment Share on other sites More sharing options...
canopy Posted September 18, 2009 Share Posted September 18, 2009 (edited) I recently posted a similar topic "How to Build a Road". Some good comments there plus this article is a must: http://theurbanrancher.tamu.edu/constructi...vewaydesign.htm In simple terms: -excavate a crowned road with drainage ditches making sure the road is higher than grade -add a road base that can harden and compact it -add a rock surface I am also in Phetchabun and recently costed this out: road base is about 150 baht per cubic meter and surface rock goes for around 500 baht per cube. The former is called luke lang and the latter heen klook. Sounded cheap until costing out a zillion truckloads of it...

chrgrims Posted September 18, 2009 Author Share Posted September 18, 2009 Ok, canopy, thanks a lot. a little bit contradicting advice, in the paper it says: The ideal situation is to make a firm base for the driveway about 4-6 inches thick using the native soil. But in the thread you started, one poster says: put small rocks as foundation. What did you do? Link to comment Share on other sites More sharing options...
canopy Posted September 18, 2009 Share Posted September 18, 2009 That is the "ideal situation" as it says, but it is doubtful your soil is suitable as is. You can either amend it as it specifies or haul in a suitable base. I think the latter may be cheaper and makes it a bit higher at the same time so recommended that. I will start soon so no first hand experience to share yet. Link to comment Share on other sites More sharing options...
chrgrims Posted September 18, 2009 Author Share Posted September 18, 2009 (edited) so you would recommend luke lang as a base. correct? what is this exactly, is it earth? would sand be an option? thanks again, maybe i can come and visit you when u start your road.

canopy Posted September 18, 2009 Share Posted September 18, 2009 Sure, you can take a look. I am debating whether to start right or wait for the rains to stop which I am told is somewhat imminent. My future place that is getting a road is in kao kho but I live close to Phetchabun city as of now. I recommend going to a place that sells rock and explain what you want. The luke lang I saw in kao kho is part clay with small rock. That is the cheapest thing but there are other alternatives. The key is you need something that will harden and shed water to keep the surface rock from sinking in. Link to comment Share on other sites More sharing options...
chrgrims Posted September 18, 2009 Author Share Posted September 18, 2009 i found a supplier of luke lang, and they are putting it on the road as we speak. i will upload a pic later. Link to comment Share on other sites More sharing options...
canopy Posted September 18, 2009 Share Posted September 18, 2009 Nice! Looking forward to seeing it. I would think the next steps would be compact it, then wait 1-2 days staying off it if possible, then add the top layer. Link to comment Share on other sites More sharing options...
chrgrims Posted September 18, 2009 Author Share Posted September 18, 2009 (edited) ok, the look lang is a bit different in the rain season, it has a bit more water. But it looks good and is firm, not like the old earth. It is not so easy to see from the pics, but the look lang consists small stone and clay. we already started using the compacter, and after a day or 2 with sun, the stones will be visible. this is the compacter we are using.

canopy Posted September 25, 2009 Share Posted September 25, 2009 I bet you have had some heavy rains on it now. How's it working out? Anything learned along the way that is useful to pass on? Link to comment Share on other sites More sharing options...
