Book Description
Selection of a technique for rehabilitation of asphalt pavement rutting is dependent on the geometrical extent of damage, and whether it is limited to the asphalt bound layers or reaching the subgrade. Overlays are not suitable when the distress is limited to the truck lane of multi-lane divided roadways. Rut-fillers are also not suitable when rutting is associated with heaves causing changes in the original profile of the pavement cross section . Milling of the damaged surface becomes a necessary part of the rehabilitation process for those above circumstances . The thickness of milled layer has to be rationally designed . The milled layer has to be replaced by arecycled or new rut resistant layer . This paper presents a study in which the main objective was to determine the thickness of milled layer that has to be replaced for the rehabilitation of pavement rutting . The procedure presented is applicable only for rutting limited within asphalt concrete layers. Full depth full width saw cut trenches together with full depth full width continuous cores were taken from the truck lane of ten rutted pavement sections . Profiles of asphalt concrete layers were used to determine the vertical extent of damage. In addition, the mean and standard deviation of rut depth and rut width along those ten pavement sections, were computed. A straight edge was used to measure the rut depth and the rut width (crest to crest distance). Simple relationships were developed relating the vertical extent of damage (thickness of milled layer) to the amount of rut depth and rut width It was concluded that the thickness of the milled layer that has to be replaced for the rehabilitation of pavement rutting should not be less than double the average rut depth or 5 % of the average rut width, along a pavement section . For the covering abstract of this conference see IRRD number 872978.

Proceedings of the 9th International Conference on Maintenance and Rehabilitation of Pavements—Mairepav9
Author: Christiane Raab
Publisher: Springer Nature
ISBN: 3030486796
Category : Technology & Engineering
Languages : en
Pages : 955
Book Description
This book gathers the proceedings of an international conference held at Empa (Swiss Federal Laboratories for materials Science and Technology) in Dübendorf, Switzerland, in July 2020. The conference series was established by the International Society of Maintenance and Rehabilitation of Transport Infrastructure (iSMARTi) for promoting and discussing state-of-the-art design, maintenance, rehabilitation and management of pavements. The inaugural conference was held at Mackenzie Presbyterian University in Sao Paulo, Brazil, in 2000. The series has steadily grown over the past 20 years, with installments hosted in various countries all over the world. The respective contributions share the latest insights from research and practice in the maintenance and rehabilitation of pavements, and discuss advanced materials, technologies and solutions for achieving an even more sustainable and environmentally friendly infrastructure.

Rehabilitation Techniques for Stripped Asphalt Pavements
Author: David R. Johnson
Publisher:
ISBN:
Category : Pavements, Asphalt
Languages : en
Pages : 180
Book Description
Asphalt stripping is a fairly common form of distress for pavements in Montana, particularly for pavements that were surfaced with an open graded friction course. Currently, the technique for rehabilitating these pavements involves the costly removal of most or all of the stripped material, prior to the placement of an overlay. The goal of this research was to determine whether the stripped material can remain in place, serving as a structural layer within the rehabilitated pavement. This study has involved the construction of five test sites, which were incorporated into larger overlay projects. At each of these sites, stripped material was removed from a control section and stripped material was left in place for a test section, prior to the placement of the overlay. Leaving stripped asphalt concrete surface material in place during rehabilitation, to be overlayed with the new asphalt concrete, did not tend to make the rehabilitated pavement more susceptible to either stripping damage or load induced damage. Life cycle cost analyses should consider rate of stripping deterioration (in./year) to new asphalt concrete to be the same, whether or not stripped material is removed prior to placing an overlay. Overlay thickness and mix design methods for resisting stripping are the important factors for extending the life of a rehabilitated stripped asphalt pavement.

Methods to Achieve Rut-resistant Durable Pavements
Author: Gerald A. Huber
Publisher: Transportation Research Board
ISBN: 9780309068529
Category : Pavements
Languages : en
Pages : 72
Book Description
This synthesis report will be of interest to state, local, and federal agency pavement materials, design, and construction engineers, as well as pavement research engineers and scientists. Those with supervisory oversight for pavement programs will also find it of interest. It describes the current practice for methods to achieve rut-resistant durable pavements. The synthesis documents current experience with permanent deformation of asphalt pavements and identifies methods to improve performance. Information for the synthesis was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search using domestic and international sources. This report of the Transportation Research Board describes the extent of the rutting problem on the National Highway System, pavement mixture design issues, and the design of rut-resistant mixtures. In addition, alternate mixture types, including stone matrix asphalt and porous asphalt, are discussed, as well as international approaches to mixture design. Finally, the construction of rut-resistant mixtures, including the role of quality control and quality assurance methods, are discussed. A summary of permanent deformation causes and solutions is included in the appendix.
