Does anyone know of where I can find some good worksheets for collecting & organizing for essential data involved in pavement design. Worksheets for traffic data, soil profiles, nomograghs, etc.
Thanks
Thanks cvg,
Are there any alternatives such as some form of trap located at the culvert to control sediment runoff? Is it normal practice to leave the sediment basin until you have reached full stablization (i.e. grass fully developed) or just until construction is finished and ground has been...
Thanks for your comments.
The state DEQ approved it without one, but the city is requiring one, stating that it is needed. I was just wondering on the reasoning why. The state manual states to have one on a site where 10 or more acres will be disturbed at any given time and also have the...
Is a sediment basin needed with the site described below.
1) All flow is directed to a single point (culvert), that has inlet protection in the form of rip rap being placed to a height of 1' foot above the top of culvert.
2) Silt fence has also been required for the perimeter of the site.
3)...
Its one of those deals where the contractor is the owner. So they are paying for it either way. They undercut three foot and found some pretty bad clay about 1'-1.5' below top of our subgrade and extremely wet.... There is some good sandy soil, with a proctor that ran 111 pcf and optimum...
I have another question pertaining to this. The Proof Roll failed and now the contractor is to repair the fail areas which is most of the Cul-de-sac of a residential subdivision. Would it be best to place the whole Cul-de-sac area since it is the majority of the area? The contractor claims the...
Fattdad,
We aren't proof rolling the binder. I just stated that because that is what will being going over the sub-base material and then we will wait for the constrution traffic to settle before applying the surface. We proof rolled the sub-base material and the city inspector noticed some...
I have a specific roadway typical section I need to model using AutoCad Civil 3D 2009 and not real sure on the best way to do this. The problem I'm encountering is in the fill conditions and applying the 1' deep toe ditch.
1) In a cut situation I need a 3:1 cut slope for a minumum depth of 3'...
As part of the new city codes the city is requiring proof roll test on all new streets that are to be later dedicated to the city by the developer. On top of our normal QC/QA testing produceres. My question is what are some of the acceptable practices.
1) At what distance from the road surface...
Thanks for the replies!!
I have found out a little bit more of the our clients intentions. He has this site that as i mentioned before, that is roughly 18-20 acres of what use to be woodland... prior to consultanting with us he cleared the site without any permits or city/state approval. SOOOO...
Kinda what I thought, but the client is dead set on getting what he wants. I think I am just going to give a rough grading plan by giving some limiting slopes criteria and enough information to maintain drainage as it is currently and just let the contractor go at it. Would this be considered...
We do have to maintain the perimeter slopes. Well I say maintain, regs just say a nice transition. the swale or ditch is really just a natural valley that begins in the front middle of the property at a pipe then extends toward the center of the property and from there its all uphill. All the...
I am working on 18 Ac. site with 30-40 feet of variation in elevation beginning with a valley running through the site and being perpendicular to the road, and then rising upward toward the side property lines. On one side of the property (prior developed) the elevation falls 20-25 feet...
Thanks for your help. That clears up some confusion on the testing side of things. I hope to get the lab out soon. The project we are working on is 3 miles of rehab. The existing structure is "believed" to be 8" of black base and 3-4" of asphalt. The current condition of the road is poor, with...
I am a young E.I. looking for some advice on things to look out for in a pavement design. The firm I work for has a soil lab, but mainly for construction material testing and quality control. Not really set up yet for design related testing. I have several questions.
1) The first question I...
