new road construction with roadcem

Construction of heavy goods haul road for eight year project: The existing pavement structure design aligned with the requirements of the Series 800 Specification
In the absence of more detailed information about the conditions on site and the for Highway Works is summarized in Figure 1 below:
expectations from the client our concept design has to be based on a number of
assumptions that are listed below.
The assumptions are made in light of the specifications for the Highway Works
Series 800 as published.
Assumptions:
• Surface Soil dry density 1800 kg/m3 (inclusive of moisture of app. 12%)
• Uniform or highly similar soil profile on all of the site
• Appropriate drainage system will be put in place to manage runoff water from
the site
• A maximum vehicle load from vehicles with 16 wheels and 6 axles has been
assumed. Total load of 80 tons; Maximum Axle load of 16 tons per axle or 8
The use of RoadCem allows us to modify the above design and, while ensuring the equivalent and
tons per wheel has also been assumed. expected better performance than the design shown in figure 1, propose the design below
• Maximum traffic intensity of 1000 axles per day over a same spot.
• Expected Minimum Time without significant maintenance 10 years
• In Situ Soil Bearing Capacity 100 MPa
• Poisson Ratio of the Soil 0.35
• Poisson Ratio of the RoadCem Construction = 0.30.
• Elastic Modulus of RoadCem Construction = 3000 Mpa
• Tyre Pressure 1000 kPa
• Wirtgen stabilizer machines or equivalent supported with a cement and RoadCem
will be used in the execution of the works.
• Static/Dynamic Roller Compactors (10 to 15 ton) and pneumatic compactors
and water tankers are will be required.
