In Japan, drainage asphalt pavement (DAP) is widely used especially on the highway and the express way. However, because of the existing porous asphalt materials consist of DAP use polymer modified bitumen, and the aggregate gradation of DAP is differ from conventional mixture, it is difficult to use those porous asphalt materials as the recycled aggregate for reclaimed asphalt pavement. Therefore, the recycling method for recycled DAP which were consisted of recycled porous asphalt materials and virgin aggregates has not been established yet. This paper describes that the recycling method for recycled DAP was considered, and the workability and five years durability was also verified by trial construction of the recycle DAP and new DAP which were consisted of virgin aggregate on the national highway.

The potential recyclability of healable asphalt mixtures has been analyzed in this paper. A healable porous asphalt mixture with steel wool fibers was artificially aged in order to assess its recyclability. This mixture was used as reclaimed asphalt in a new porous asphalt mixture, whose mechanical and healing capacities were studied and compared with the behavior of the original porous asphalt mixture. The quantity of reclaimed asphalt mixture added was 40%; besides, in order to recover the properties of the aged binder, and incorporate the last advances in the recyclability of bituminous mixtures, a rejuvenator was also added (SYLVAROAD™ RP1000). The voids test, Cantabro particle loss test, water sensitivity test, stiffness test, and fatigue resistance test were performed to mechanically study the experimental mixture, while the last one (fatigue resistance test) was also used to assess its healing capacity. The results have shown that the healing capacity of the original healable porous asphalt mixture is maintained with similar mechanical performance.

Based on the background of continuously increasing requirements on the performance of recycle pavement materials, the effect of rejuvenator with different content (3%, 6%, 9% and 12%) and different type on recycled porous asphalt mixture was studied in this paper. The results shown that comparing with the ordinary rejuvenator which softening the aged binder effectively, the modified functional rejuvenator can also enhance the temperature stability and deformation resistance capacity of aged asphalt. In addition, the recycled porous asphalt mixture with modified functional rejuvenator has more excellent high temperature stability, water stability and fatigue performance. The result has great significance for the development of pavement recycling technology.

Runoff Control

We examined the possibility of improved runoff control in a porous asphalt pavement by installing beneath it an infiltration pipe with a numerical simulation model that can simulate rainfall infiltration and runoff at the porous asphalt pavement. From the results of simulations about runoff and infiltration at the porous asphalt pavement, it became clear that putting a pipe under the porous asphalt pavement had considerable effect, especially during the latter part of the rainfall.

Porous asphalt (PA) mixtures are more environmentally friendly but have lower durability than dense-graded mixtures. Additives can be incorporated into PA mixtures to enhance their mechanical strength; however, they may compromise the hydraulic characteristics, increase the total cost of pavement, and negatively affect the environment. In this paper, PA mixtures were produced with 5 different types of additives including 4 fibers and 1 filler. Their performances were compared with the reference mixtures containing virgin bitumen and polymer-modified bitumen. The performance of all mixes was assessed using: mechanical, hydraulic, economic, and environmental indicators. Then, the Delphi method was applied to compute the relative weights for the parameters in multi-criteria decision-making methods. Evaluation based on distance from average solution (EDAS), technique for order of the preference by similarity to ideal solution (TOPSIS), and weighted aggregated sum product assessment (WASPAS) were employed to rank the additives. According to the results obtained, aramid pulp displayed comparable and, for some parameters such as abrasion resistance, even better performance than polymer-modified bitumen, whereas cellulose fiber demonstrated the best performance regarding sustainability, due to economic and environmental benefits.
