Low Volume road design
Low Volume road design
(OP)
Guys
I am designing a low volume road for haul roads in a wind project. For the design, is there any established correlation that can be used for estimating the CBR value from aggregate base material gradation?
What is the governing CBR for the low volume(haul road design), is it the CBR of the subgrade or CBR of aggregate material?
Please let me know.
Thanks
NT

Thanks for the reference. Can you please provide me with the reference for the soaked CBR to be used in the design. For low volume road design, I am using the CBR based equation for calculating the EBS (elastic modulus of base material).
The equation is EBS= 17.6 X (CBR)0.64 EBS: in MPa
I am wondering if a soaked CBR or CBR at OMC needs to be used here.
Is there any reference for this.
Thanks for your time

Can you please provide reference for the "Scala penetration tests", I haven't heard of them before.
Thanks

These are used a lot in Australia/NZ. Might be called a DCPT (Dynamic Cone Penetration Test) if you're in the USA
