Road Pavement design for internal road network of factory building

[Thusitha2222]

I got a job to design road Pavement for internal road network of factory building. They preferred Asplalt for surfacing. Are there any specific guidelines available for that?

PS: I'm highway design engineer, I know how to design public roads, here I want know about, are there any specific guidelines for traffic forecasting or traffic class evaluation for factories. Also what vehicle types need to consider. (ie. Fork lift)
Thanks for your valuable replies.

Have you ever designed a pavement?

There are many guidelines out there, depending on where you are located. In the US, AASHTO is the most common method used. Before you get starting on the design process you'll need to know a few things, such as:

What loads will be put on the pavement
How many times will those loads be repeated (frequency of loading)
What are the subgrade soil conditions
Where is the water table (will you need underdrains)
What is the availability of competent base material
What type of asphaltic concrete will be used
How will surface drainage be handled

As for design approaches, you have several options. You can use the common structural number approach, a traffic factor approach (Asphalt Institute method) or you can use elastic layer analysis.

As Ron has suggested there are many guides out there. Here in the UK and in the US. The vaugness of your question suggests you have no experience in this field and you need assistance from someone who does. Do you have a experienced engineer you can ask?
Ron has addressed the many factors related to the structural design of the road but you also need to consider, size of vehicles, horizintal (especially) and vertical alignment. types of kerbs, tunring points. junctions. drainage. Pedestrian safety and segregation.

Hire someone who know this field.
We had in plant roads, and they were designed for heavier loads that public streets.
Something to with having fork trucks that could carry 50,000lb loads, and unloaded they were about 60,000lb.
