Similarly, aging also affects the recycled asphalt mixture. Li et al. found that the secondary aging behavior had a faster effect on the rutting and cracking performance of the warm-mix asphalt mixture.

Therefore, these results at high test temperature (60 °C) seem to indicate that CR-modified mixtures are stiffer than the conventional polymer modified asphalt mixture. After aging, the reference mixture reduces its flow and increases its stability, resulting in a higher MQ value. As expected, the mixture is stiffer due to the effect of aging.

Consider the use of colored asphalt and light aggregates and/or porous asphalt in areas where urban heat island (UHI) effects are of concern (EPA 2005). Use porous asphalt and open-graded friction courses in an integrated manner to enhance safety, provide positive drainage, and recharge groundwater (see . NAPA Porous Asphalt. website).

Using the waste crumb rubber modified asphalt to pave the road surface could reduce cost and save energy. However，in order to obtain adequate workability, the mixing temperature and compaction temperature of rubberized asphalt binder and its mixture is much higher than those of conventional asphalt mixtures. Warm Mix Asphalt (WMA) is the name given to certain technologies that reduce the

Asphalt is 100 % recyclable and can be used to produce new hot mix asphalt. In some countries Reclaimed Asphalt Pavements (RAP) is the most recycled product. The techniques that are being developed now are not only related to the recycling of asphalt but also to other materials/additives with the aim to reduce energy and costs by keeping/increasing

A further study evaluated the effect of antioxidants on retarding of asphalt mixture aging using the GPC technique. An antioxidant, hydrated lime, and linear low-density polyethylene were used when preparing the dense-graded asphalt and the stone-mastic asphalt mixes, and the effect of aging retardation was evaluated using GPC.

Functional Pavement Design is a collections of 186 papers from 27 different countries, which were presented at the 4 th Chinese-European Workshops (CEW) on Functional Pavement Design (Delft, the Netherlands, 29 June-1 July 2016). The focus of the CEW series is on field tests, laboratory test methods and advanced analysis techniques, and cover analysis, material development and production

Warm Mix Asphalt (WMA) is the greatest advance in asphalt technology since recycling and has revolutionary implications for the asphalt paving industry and environment. By lowering the temperatures at which asphalt mixes are produced and placed on the road by 50 to 100 degrees Fahrenheit, WMA benefits the producer by cutting fuel consumption

The first priority of this invention is to provide the composition and the manufacturing method of a noble highly viscoelastic warm-mix modifier that can be added to asphalt binders for the purpose of reducing environmental pollution, saving natural resources by recycling RAP aggregates, reducing construction cost, and minimizing maintenance cost by extending pavement life-cycle.
