The fat clay is highly saturated and soft. The PI of this material is 50. RCEJD, I appreciate if you could please let me know the location of perventive treatement you applied. Was is at the toe zone? If the preventive treatment was at the toe zone, what was the depth of the treatment?

Thank you for the suggestions. The embankment will be placed at a slope of 3:1 on top of highly saturated silty fat clay (toe area). Probably field exploration & lab tests will give an idea about the characteristics of the material, but the contractor is not very keen to spend more money for...

Thank you for the reply. I am curious to know how you came to a conclusion “it is fine just how it is”. I hope my first post did not give a complete situation of the location. At the stated location, the placement of controlled fill is not done, but the developer likes to build the land...

Highly saturated area was encountered at the toe while placing engineered controlled fill with a slope of 3:1 to a height of approximately 30 feet. It was noted that the location was a small lake, drained and filled about 50 years ago. According to the observation, the material mainly consists...

I would appreciate if someone could help me to find a comparison of the design of life service for a flexible pavement, treating the subgrade with flyash, granular base or full depth asphalt pavement. Pls. let me know if we could find a table in any books or web sites regarding the service...

I appreciate if someone could post a jouurnal/or book related to Pseudo Static Analysis. Thanks!

What should be the concrete placement methods to be monitored for a mass concrete having a size of 10m * 10m* 25m ? And also, what type of concrete mix design should be specified as concrete mix so that to maintain low heat of hydration in the mass concrete?

How can we transform the computed equivalent length, which is a minor losses to get the total sewer line flow rate?

Thank you bridgebuster for your info. According to my computation, the thickness of the rigid pavement is about 6.5". What is the considerate rigid pavement thickness for a collectoral road?

I'm working on a rigid pavement design. The only data I have is AADT, which is 10000. How do we design ESAL (W18) with the available data?

WannabeEIT: Thank you so much for your information.

Thank you for the remarks!! According to the changes to expect in the 2008 edition of the ACI building code (ACI 318-08) in chapter 5, the Code has adopted to use of three 4” x 8” cylinders as equivalent to the use of two 6” x 12” cylinders for determining compressive strength.(CI Journal...

According to ACI and ASTM new/ revised standards on concrete sampling/ or testing, concrete sampling can be tested by using 4” * 8” cylinders instead of 6” * 12” to find the compressive strength of the concrete. According to my understanding, instead of 6” * 12” with 2 cylinders for 28 days...
