TL;DR: In this article, a geosynthetic-reinforced chip seal layer with high-reflectivity aggregates is used to reduce the temperature in asphalt pavements and therefore reduce the potential of rutting and the rate of aging.
Abstract: High temperatures in asphalt pavements lead to rutting and age-related cracking. Although beneficial for reducing distresses, thicker layers are not generally used in low-volume roads because of cost restrictions. This paper presents an alternative approach in which a geosynthetic-reinforced chip seal layer with high-reflectivity aggregates is used to reduce the temperature in asphalt pavements and therefore reduce the potential of rutting and the rate of aging. If the absorption of the surface of the pavement is lowered and the conductivity of the layers is reduced, then less heat will penetrate through the depth of the pavement, and a lower pavement temperature will result. The absorption at the surface can be reduced through the use of a surface layer with greater reflectivity, and the conductivity can be reduced with the help of a layer of a material that has very low conductivity. Therefore, a composite pavement system can be used for low-volume, asphalt-surfaced roads; the system would incorporate a...

TL;DR: In this article, a simple method is proposed to calculate the maximum pavement temperature profile on the basis of maximum air temperature and hourly solar radiation, which is used mainly for Strategic Highway Research Program binder and mixture specifications.
Abstract: A simple method is proposed to calculate the maximum pavement temperature profile on the basis of maximum air temperature and hourly solar radiation. The method was developed to be used mainly for Strategic Highway Research Program binder and mixture specifications and as a quick method of determining maximum pavement temperature for various regions in the United States and Canada. The method is based on the energy balance at the pavement surface and the resulting temperature equilibrium. Reasonable assumptions are made regarding thermal properties of the asphalt concrete. The accuracy of the method was tested by applying it to some field cases for which measured pavement temperatures were available. In 83% of the cases, the proposed equation predicted the pavement temperature within 3 deg C, which is well within reasonable limits, considering the numerous uncertainties that exist in material properties, accuracy of measurements, variability of environmental factors (wind, sunshine, etc.), and inclination of the pavement surface in receiving radiation.

TL;DR: In this paper, a series of sequential analytical models were developed to predict the aging (viscosity increase) characteristics of conventional "S" type asphalt cements due to both short and long term effects.
Abstract: One of the major issues in the development of the performance based specification for asphalt pavements is the binder characterization and its relationship to pavement performance. Among the various factors used for binder characterization, the durability or hardening property of asphalt binder is one of the key factors. This paper describes a series of sequential analytical models that have been developed to predict the aging (viscosity increase) characteristics of conventional "S" type asphalt cements due to both short and long term effects. These models were developed from a statistical analysis of results in a Master Data Base comprised of asphalt consistency results and synthesized from 40 field projects throughout North America and Europe. The data base contained over 2300 separate line entries relating to consistency information obtained at either a given time and/or depth within the asphalt pavement layer from a particular field project.

TL;DR: In this paper, the authors provide an up-to-date guide to the properties and applications of bitumen for the civil engineer in road and airfield construction and maintenance. And they provide an update on the standard procedures and methods necessary for using asphalt.
Abstract: This handbook provides an up to date guide to the properties and applications of bitumen for the civil engineer in road and airfield construction and maintenance. This edition has been fully revised to reflect the many recent advances in asphalt technology, including the development of new mixtures, improved understanding of the mechanisms by which pavements fail, and the availability of high performance bitumens. Other new topics include high friction and coloured surfacings, and recycling asphalts. The handbook also provides an update on the standard procedures and methods necessary for using asphalt.
