ASPARi

The ASPARi in Contracts document is finalized. After almost 3 years of meetings, discussions, demonstration projects, and even more discussions, Asfaltimpuls' High Tech Low Cost (HTLC) commission is rounding off its work. Its efforts have resulted in the attached draft document. This document provides a further explanation of the way in which the ASPARi philosophy can be used to record and improve the asphalt construction process by means of a Process Quality Improvement (PQi) measurement. The document has been prepared to explain commonly used terms and includes recommendations for including PQi measurements in contracts.

 

First of all, the general introduction presents an overview of recent developments and backgrounds. Subsequently, in PART 1, the practical use of the PQi instrument is explained in more detail, and instructions are given on how this can be included in contracts. For interested clients, contractors, and related parties, PART 2 presents a more extensive and in-depth perspective with which a (future) vision and direction can be formed for further development of the PQi method in the Quality Assurance activities of an asphalt contractor.

 

We are indebted to several people in reaching this milestone. The initial discussions to have the ASPARi PQi methodology integrated into contracts were started by Frank Bijleveld (Strukton) and Kees Nelissen (Gemeente den Haag). Together with Erwin Vega (CROW) and Seirgei Miller (ASPARi, University of Twente), the group prepared an Asfalt Impuls proposal and plan of action. The arrival of Berry Bobbink as project manager provided the much-needed impetus for collaboration with public clients and resulted in the group's current expanded membership. This draft document has mainly been prepared by Marco Oosterveld and Marjolein Galesloot (BAM Infra), and Berwich Sluer (Boskalis).  Valuable contributions and comments have been provided by: Seirgei Miller (ASPARi, University of Twente), Berry Bobbink (BB Infra Asfalt Advies), Frank Bijleveld (APA, APRR, APT), Ric Vergeer, Carla Vosmaer (Provincie Noord-Brabant), Wim Rolff of Roelofs (Gemeente Amsterdam), Robbert Rouwenhorst, Mathieu van den Hurk (Provincie Gelderland), Wouter Heijsser (Heijmans), and Harco Kersten (Rijkswaterstaat).
