Abstract

In the spring of 2000 Ribe County decided to outsource part of the road maintenance work. A work group was established consisting of representatives from counties and contracting companies in order to work out procedures, terms and conditions for outsourcing of road maintenance and in order to determine which parameters could be used for quality assurance. In Denmark the bearing capacity was selected as one of the parameters for quality assurance. The bearing capacity was to be measured by means of a falling weight deflectometer (FWD). In order to find out how these values could be of benefit, a decision was made to start a test project in order to determine the degree of repeatability of the FWD measuring procedure. The testing results were to form the basis of the procedures, terms and conditions to be set up for the use of bearing capacity measurements performed by means of FWD in connection with outsourcing contracts. The paper presents the testing part dealing with repeatability and the season variations in the calculated residual life and reinforcement needs. For the covering abstract see ITRD E118503.

与外判合约有关的水务署测量的验证

2000年春，里伯县决定将部分道路养护工作外包。设立了一个工作组，由各县和承包公司的代表组成，目的是制定将道路维修工作外包的程序、条款和条件，并确定可用于质量保证的参数。在丹麦，承载力被选为质量保证的参数之一。承载能力是通过一个下降重量偏转计(FWD)来测量的。为了找出这些值的益处，决定启动一个测试项目，以确定FWD测量过程的可重复性程度。测试结果将构成程序、条款和条件的基础，这些程序、条款和条件将由富卫署就外判合约进行承载力测量。本文介绍了计算剩余寿命和补强需求的重复性和季节变化的试验部分。相关摘要见ITRD E118503。
