Apart from considering surface texture for pavement maintenance purposes (Pavement condition evaluation etc.), is there any specification used for freshly constructed asphalt concrete (HMA) pavements? If so, what are the specified limits?
Hi,
Nalaka Jayantha I believe if you could read this "STANDARD CONSTRUCTION SPECIFICATIONS FOR ASPHALT SURFACING DIVISION 40 INDEX" which is very helpful.

Hi Zuhair Kadhim Jahanger ,
Thank you for your answer.
I referred to that spec. But not found any specified values for texture 😢
Did you need specification limits zone depending on the Asphalt type?
Hi Zuhair Kadhim Jahanger
Yeah, typically we are using dense graded asphalt mixes with 60/70 bitumen.
I need to know whether there are any specification limits for MTD or the skid number of the freshly constructed pavement. Do you have any idea about that?
Thank you for your interest in this question
Dear
You can use sand patch method for measuring the macro texture and British pendulum for micro texture determination.
Saad Sarsam Yeah, but what are the specified limits for BPN and MTD for a fresh asphalt pavement?
Both testing are implemented for obtaining the coefficient of friction. The limits for that depends on the design speed and class of the roadway.
