Pavers version 2.9
February 1, 2016
Pavers version 2.9 is suitable for Windows 10 applications. The 'look-and feel' of the interface as well as the accuracy have been improved. The accuracy of the lateral wander concept for concrete pavements is further improved.

Pavers version 2.83
September 21, 2014
Service update v2.83

Pavers version 2.81
September 14, 2011
Service update v2.81

Pavers version 2.8
January 14, 2008
Pavers version 2.8 is Windows Vista capable. In this version, the automatic bulk-back-calculation procedure using Excel in- and output has been made even more easier.

Pavers version 2.62
February 20, 2007
The range of the field temperature has been extended correct back calculated asphalt stiffness to a standardised reference condition of T_mix for the uniformly-distributed pavement temperature.

Pavers version 2.61
March 12, 2006
Full service update released with enhanced ACN & Aircraft load database.

Pavers version 2.6
September 25, 2005
The Pavers program fully supports the ‘Guidelines on PCN Assignment in the Netherlands’. CROW has selected Pavers ® as the preferred program to use for the PCN assignment of flexible and rigid pavements as is presented in the Guideline. 

Pavers version 2.53
March 31, 2005
The PCN assignment module has been extended for the automatic determination of a PCN for a mix of to be composed by the evaluator. The aircraft database now also contains ACN-data.

Pavers version 2.52
December 2, 2004
The Pavers program supports the ‘Guidelines on PCN Assignment in the Netherlands’. Small revisions to accommodate stress related transfer models were made. The general transfer functions for cemented materials in rigid and flexible pavement was enhanced to allow strain and stress based fatigue performance functions. The user can define the performance (transfer) functions either on a log-log or on a log-linear basis.

Pavers version 2.5.1
October 20, 2004
The LCN-load curves were fitted in the program to accurately determine the pavement’s LCN-LCG load carrying capacity.

Pavers version 2.5
June 17, 2002
A rigorous and improved multi-slab model was built in to cater for stabilised bases under rigid pavement.

Pavers version 2.12
April 29, 2002
A comprehensive load data base was added, containing the gears and load data of over 200 military and civil aircraft.

Pavers version 2.1
December 11, 2001
The Graphical User Interface (GUI) was revised and renewed to allow intuitive use of the program.

Pavers version 2.0
February 28, 2001
Pavers was enhanced with a subroutine to read in deflection basins and construction data directly from Excel files. The added automated back-calculation routine bulk processes the pavement model and writes the output to the Excel file. The back-calculated data can be inputted in the Pavers program for further processing.

Pavers version 1.0
July 12, 1999
Pavers version 1.0 was developed for the Dutch Ministry of Defense for use in the Netherlands only. Pavers is the logical continuation of the UEC-Slab model developed at CROW.

Bound Base version 1.12
October, 28, 2011
Broader range with wider boundaries to characterize new bound materials.

Bound Base version 1.11
April 11, 2010
Revision of printed output listing includes service update.

Bound Base version 1.1
March 14, 2009
Reflective cracking can be delayed effectively when a sufficient thick asphalt cover is constructed. New relations between elastic modulus and cover thickness have been added for main, secundary and tertiary roads.

Bound Base version 1.02
July 14, 2005
Service update fixing minor interface typo errors.

Bound Base version 1.01
December 15, 2004
A bug concerning the input of the annual growth factor was fixed. The traffic library was adjusted to Vencon 2.0, CROW's program for designing concrete pavements.

Bound Base version 1.0
February 7, 2004
The Pavers Team is proud to announce the release of Bound Base. This handy tool can be used for the design of the required thickness of a stabilised base in a rigid or flexible pavement. It is the missing link in RWS/DWW’s ASCON tool, used for the design of pavements in the Netherlands for the design of flexible pavements with granular bases.
