Concrete Road Design Spreadsheet – TRL 87 Method

This suite of 5 spreadsheets undertake the structural design and analysis of a concrete highway using the TRL 87 Method.

The empirical TRL 87 Method originates in the UK and is the accepted method of highway structural design in the UK.

The spreadsheet calculates the required concrete slab thickness to achieve the user input traffic load with the user input concrete and subgrade strengths. Spreadsheets are included for unreinforced, conventionally reinforced and continuously reinforced concrete pavements in accordance with TRL 87.

Each spreadsheet includes unique features to analyse the effects of altered traffic load requirements, concrete specification and subgrade strength allowing the designer to quickly specify a concrete pavement design to suit any required traffic load.

An additional spreadsheet is included to assist the designer in calculating the required traffic loading in Million Standard Axles (MSA) for use in the main design spreadsheets.

The suite includes a total of 4 spreadsheets;

  • An unreinforced concrete pavement design and analysis spreadsheet based on TRL 87 Guidance
  • A conventionally reinforced concrete pavement design and analysis spreadsheet based on TRL 87 Guidance
  • A continuously reinforced concrete pavement design and analysis spreadsheet based on TRL 87 Guidance
  • A Traffic Load Assessment spreadsheet which calculates the equivalent MSA traffic loading from a variety of standard heavy vehicles. This allows the designer to accurately optimise their pavement design based on site specific loading requirements.
  • A Wheel Load Assessment spreadsheet which calculates the equivalent MSA traffic loading from a user defined maximum axle load and loading frequency
