CIRTEX ADVANCED PAVEMENT DESIGN PROGRAM

Intended use

CAPLab is an innovative and easy to use tool intended to assist a pavement designer with selecting the appropriate geogrid, geotextile, and pavement section thickness, based on the referenced engineering standards, testing, and research. Further information and guidance is available on the Cirtex website and forms a part of this introduction. http://www.cirtex.co.nz/2016/03/caplab-release/

Design Methodologies

The following is an overview of the two design methodologies used by CAPLab; for further information and copies of the research papers and source data relating to the design methodologies, please contact Cirtex on 0800 247 839.SIL & Fig 8.4 Method. This method uses a subgrade improvement layer generated from empirical data from the manufacturer Naue GmbH & Co (‘Naue’) based on the proven performance of the SecuGrid and CombiGrid range of geogrids to improve the modulus of the subgrade from the input figure to E = 80 MPA. From this improved figure the pavement depth is calculated using the formula from the Austroads Figure 8.4 chart (or Fig 8.5 from Austroads AP-T36/06 for ESA ≤ 105) to give the appropriate pavement depth. A conversion of E = 10*CBR is used. A customised version of CAPLab is available with other conversion formula if required.

Perkins 2014 Fig 7.4 Method. This method is based on the work of Dr Steve Perkins as outlined in his paper “Modification of Austroads Empirical Design Charts for Paved Roads Reinforced with a NAUE Geogrid.” It is based on extensive finite element modeling and is calibrated to the performance properties of SecuGrid® and CombiGrid®, and the modified Austroads charts as presented in the above-mentioned paper.

Construction Notes

Sub base aggregate must be a well graded crushed rock, base course material must be M/4 AP40 base course or as directed by the project engineer. Compaction must be in lifts of no more than 200mm to 98% MDD. Site engineer to confirm characteristic subgrade strength before starting construction.

Refer to the SecuGrid® installation instructions for details on installation, joining, and overlapping of the geogrid.

http://www.cirtex.co.nz/product/secugrid-multi-directional-geogrid/

SecuGrid® and DuraForce® may be substituted with the appropriate grade of CombiGrid if required. A geogrid with lower stiffness parameters must not be used. Best practice for pavement construction as regards drainage and detailing must be followed as set out in the applicable local regulations and project documents.

Important note: refer to the information section of the CAPLab program for details of the design methodology and derivation of the figures used. This suggested pavement layout is not to be used for construction until approved by a suitably qualified engineer.

PROJECT DESIGN OPTIONS

Technical Support

Technical support is our standard, no-cost customer support which is available by telephone, email or during sales representative’s routine visits during normal business hours to provide support on our range of products and their suitability for a given project. This support can include data sheets, case studies and other relevant technical backup and a quotation if required.

This support is based on our understanding of your requirements and assumed or client supplied site information. Any specifications, sketches, plans or drawings provided by us do not necessarily relate specifically to a particular project or site, and should not be relied on as such.

Should you require further design assistance we can either offer our in house concept design service or alternatively, full 3rd Party Design which is provided by a 3rd party registered engineer.

Project Concepts

This level of support is normally carried out by our in house technical team and is very useful for establishing concepts used for proposals and costing purposes. Project Concepts can often form part of the full 3rd Party Design should you make a decision to obtain a 3rd Party Design at a later date. Outputs for this service will vary depending on the application and situation, however, will normally include reinforcement layout, type and strength required for reinforced slope and wall applications, anchor selection guidelines for Earth Anchoring applications, and CAD drawings and installation guidelines. Details of what will be provided can be discussed with one of our technical team. For earth anchoring applications a site pullout test is often included in the concept design phase.

This level of design carries no contractual warranty and a producer statement is not provided. This service is based on assumed or client supplied information. You should ensure that any outputs from a Project Concept service are checked by a suitably qualified and certified engineer instructed by you. Our technical team will provide the relevant calculations and drawings to your engineer and will cooperate with the engineer.

Any costs associated with this service will be discussed at the time of acceptance.

3rd Party Design

If 3rd Party Design is required, it is carried out by a suitably qualified and registered 3rd party engineer. Prior to providing a quotation for this type of design, in depth discussion will be carried out to establish the exact requirements of the client and scope of the design. Each design is costed accordingly and based on the work involved to fulfill the requirements of the client. These costs will be defined in the engagement documentation. The Project Concept Design can often be utilised to reduce the overall cost to the client in this stage.
