Accelerated pavement testing of load transfer through aggregate interlock and the influence of crack width and aggregate type - a case study

Author: Du Plessis, L ; Strauss, PJ ; Perrie, BD ; Rossmann, D Date: Oct 2007 This paper discusses the prediction of crack width using the International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM) model which predicts early age shrinkage. The model was modified to include ... Read more
Caltrans accelerated pavement testing (CAL/APT) program - test results: 1993-1996

Author: Nokes, WA ; Harvey, JT ; Du Plessis, L ; Long, F ; Stolarski, PJ Date: Aug 1997 By combining the results of both the HVS and laboratory tests, interpretations of pavement performance are described and recommendations for pavement design and construction have been made to Caltrans. Read more
Comparison of accelerated pavement test results with long term pavement behaviour and performance

Author: Jooste, FJ ; Kekwick, SV ; Sadzik, ES ; Rohde, GT Date: Aug 1997 The aim of this study was to investigate the following:how accelerated pavement testing predictions compare with actual road behaviour and performance the relative influences of load and environmental factors on pavement deterioration and how ...

Conceptual performance model for deep in situ recycled pavements with cement and bitumen additives

Author: Steyn, WJvdM ; Sadzik, E ; Semmelink, CJ Date: Oct 2001 The purpose of this paper is to provide information regarding a conceptual performance model for Deep in Situ Recycled (DISR) pavements where both cement and either foamed bitumen or bitumen emulsion have been added to the mix. CSIR Transportek ... Read more
Cost benefit analysis of the California HVS program

Author: Du Plessis, L ; Rust, FC ; Horak, E ; Nokes, WA ; Holland, TJ Date: Oct 2008 The University of California, through the UC Pavement Research Centre (UC-PRC) located at Davis and Berkeley, started conducting Accelerated Pavement Testing (APT) research in 1994. This research is conducted for the California Department of ... Read more
Evaluation of deformation response of HMA under APT and wheel tracking tests

Author: Denneman, E ; Steyn, WJVDM ; Maina, JW ; Sadzik, ES Date: Oct 2008 This paper is based on a study into the rutting performance of HMA which forms part of the larger research initiative. The objective of this phase is to identify and develop appropriate test protocols and associated acceptance criteria for ... Read more
Evaluation of precast concrete slabs using a heavy vehicle simulator

Author: Kohler, E ; Harvey, JT ; Du Plessis, L ; Theyse, HL Date: Oct 2008 Precast slabs are considered an attractive pavement option for rehabilitation or reconstruction cases where traffic closures of less than eight hours are required. Benefits include long life expectancy of concrete cast in factory-controlled ... Read more
Heavy vehicle simulator in accelerated pavement testing: a historical overview and new developments

Author: Du Plessis, L ; Coetzee, NF ; Burmas, N ; Harvey, JT ; Monismith, CL Date: Oct 2008 The purpose of this paper is twofold. Firstly, it will provide a brief description of the technological developments involved in the Heavy Vehicle Simulator (HVS) accelerated pavement testing equipment. This covers the period from its conception ... Read more
Heavy vehicle simulator testing of trial sections for CALTRANS.

Author: Rust, FC ; Du Plessis, L ; Verhaeghe, Benoit MJA ; Grobler, JE Date: Oct 1993 Internationally, interest in accelerated pavement testing (APT) is increasing, in particular testing with mobile machines which allow the performance of in-service roads to be assessed. The Californian Department of Transportation (CALTRANS) ... Read more
Moisture related test protocols for HVS testing

Author: Denneman, E ; Steyn, WJVDM ; Maina, JW ; Sadzik, ES Date: Oct 2008 In order to provide guidance on the possible methodologies for evaluating specifically moisture related pavement response using the Heavy Vehicle Simulator (HVS), this paper describes the objectives, potential effects and available methods ...

Provisional results from accelerated testing of ultra thin-layer reinforced concrete in South Africa

Author: Du Plessis, L ; Strauss, PJ ; Kilian, A Date: Aug 2009 The CSIR Built-Environment, in conjunction with the University of Pretoria and the Cement and Concrete Institute of South Africa, developed a low cost option for the upgrading of unsurfaced (gravel) roads. The proposed solution is the placing ... Read more
Simulation of temperature conditions on APT of HMA mixes

Author: Steyn, WJVDM ; Denneman, E Date: Oct 2008 The objectives of this paper is to provide guidance on the practical management of temperature (pavement and loading tires) in Heavy Vehicle Simulator (HVS) tests, the potential effects of these temperatures on the outcomes of the test and ...

Thin asphalt and double seal rehabilitated lightly cemented pavements: evaluation of structural behaviour and life cycle costs

Author: Steyn, WJvdM ; De Beer, Morris ; Visser, AT Date: Aug 1997 The aim of this work was to quantify the structural behaviour of rehabilitated pavements and to optimise the life-cycle cost for the road agency. Read more
Three decades of development and achievements: the heavy vehicle simulator in accelerated pavement testing

Author: Verhaeghe, Benoit MJA ; Sadzik, E ; Visser, A Date: Aug 2006 Since the 1970s, the South African Heavy Vehicle Simulator (HVS) Programme has had a major technological and economic impact on the design, construction and maintenance of South African roads. It has impacted, for instance, on the development ... Read more
Tyre-pavement contact stress patterns from the test tyres of the Gautrans heavy vehicle simulator (HVS) MK IV+

Author: De Beer, Morris ; Sadzik, EM ; Fisher, C ; Coetzee, CH Date: Jul 2005 This paper addresses the measurement (i.e. “fingerprinting”) of tyre loading and contact stress patterns associated with slow moving test tyres on the new Heavy Vehicle Simulator (HVS Mk IV+) of Gautrans. The two test tyres used on the HVS ... Read more
