“…Porous asphalt pavement has various advantages such as a high void ratio, large frictional resistance attributed to the rough surface, skid and rutting resistance, and sound absorption and noise reduction [1,2]. erefore, it can reduce the thickness of water film on the pavement, water spray, and noise in wet weather, thus improving the skid resistance and enhancing driver safety [3][4][5]. us, porous asphalt pavements have been widely used in many countries [6].…”

In order to evaluate the possibility of the application of warm mixing technology in high-viscosity asphalt mixture, in this paper, the effects of surfactant warm-mix additives (WMAs) on physical and rheological properties of high-viscosity asphalt (HVA) which was prepared with self-developed SBS/C9 petroleum resin blends (SPR) modifier were measured. The results indicate that the addition of WMA can decrease the viscosity and softening point but improve the penetration and ductility of warm-mix HVA. With the increase of the content of WMA, the modulus, failure temperature, viscosity, and recovery rate of warm-mix HVA all increased at first and then decreased, and the maximum value appeared when the modifier content was 1.0%–1.5%. Moreover, when the amount of WMA is 1.5%, the low-temperature performance of warm-mix HVA reaches the best value. Thus, the amount of WMA is of great importance for the warm-mix HVA, and in order to achieve ideal rheological properties, the recommended amount of WMA is 1.0%–1.5%. Considering economic improvement and environmental protection, WMA could be an alternative for increasing the workability of HVA.

“…In order to capture the internal structure of asphalt mixtures and evaluate the effects of air void distribution, X-ray Computed Tomography (CT) and digital camera processing have been widely used non-destructive imaging technologies, which could provide a 2D or 3D image of the internal structure of a solid object [12]. From the digital camera or CT image processing, the location or coordinates of aggregates, reconstructed pore geometry, void-distribution segregation, the two-or three-dimensional internal structure of hot-mix asphalt or some distresses like cracking can be obtained [13][14][15][16][17][18]. As an increasing number of researchers have analyzed the asphalt pavement from the microstructure perspective [19][20][21][22][23], some of them have applied digital camera and CT image processing in the field of asphalt pavement, especially in terms of air voids.…”

The air voids distribution has a significant effect on the pavement performance related distresses such as rutting, cracking, moisture damage and permeability. However, most studies only quantified the air voids by average content, ignoring the heterogeneity inside the materials. This study focuses on the heterogeneity of air voids distribution inside the open-grade asphalt mixture based on 2D image analysis. Equivalent aperture is proposed to measure the area of each air void. Results showed that along both vertical and horizontal sections inside the open-grade asphalt mixture, the number of voids with 0~2 mm equivalent aperture would have a great impact on the total number of voids, while large amounts of small voids would not significantly affect the total voids number. Additionally, voids with 0~4 mm equivalent aperture account for the largest proportion, and when the equivalent aperture is beyond 4 mm, the number of voids would decrease as the equivalent aperture increases, regardless of the void areas. Furthermore, in both vertical and horizontal sections, as the equivalent aperture increases, the speed to accumulate voids area would firstly increase and then decrease. As the equivalent aperture increases, the contribution to the total voids area would increase accordingly, and it would approach the peak when the equivalent aperture reaches about 8 mm.

“…Despite of, some authors define to these porous asphalt mixes as thin layers without structural capability, the resilient modulus found is a clear evidence that this sentence could be refused. Regarding aforementioned, a recent research (Moriyoshi et al, 2014) showed a comparison between HMA and PMA performances after seven years placed, assessing properties such as rutting using the TRRL wheel tracking test and a contact pressure equal to 0,54 MPa. They found that rut depth for PAM was less than HMA, it is, 1 mm and 6 mm, respectively.…”

Porous asphalt mixes (PAM), conform a special road surface for asphalt pavement structures. They have a distinctive particle size distribution that permits infiltration of the runoff storm water due to its voids content which is about 20 %. Many researchers have conducted studies and concluded that the use of modified asphalts is completely necessary to design PAM. Organic and chemical additives and special procedures such as foamed asphalt and including fibers into the mixture design have enhanced the performance of PAM, during its service life. This paper is based on the mechanical characterization of PAM and how the asphalt binder modified with fatty acid amides, influenced on their behavior and performance. In order to do so, an experimental methodology based on laboratory tests aimed to establish a comparison between porous asphalt mixes, designed and produced with a 60-70 in 1/10 mm penetration at 25 °C neat asphalt binder, and another using modified asphalt with fatty acid amides.Keywords: Modified asphalt, porous asphalt mixes, hot asphalt mixes, hydroplaning, fatty acid amides, Cantabro test. RESUMENLas mezclas asfálticas porosas (PAM), conforman una superficie de rodadura especial para los pavimentos flexibles. Tienen una granulometría característica, lo cual permite la infiltración de las aguas de escorrentía pluvial, gracias al contenido de vacíos que posee, alrededor del 20 %. Muchos investigadores han realizado estudios que han permitido concluir que el uso de asfaltos modificados es completamente necesario para diseñar las PAM. Aditivos químicos y orgánicos y procesos especiales tales como el de asfalto espumado y la inclusión de fibras en el diseño de la mezcla, han mejorado el comportamiento de las PAM, durante su periodo de servicio. El presente artículo aborda la temática de la caracterización mecánica de mezclas asfálticas porosas (PAM) y hace énfasis en cómo el cemento asfáltico modificado con amidas de ácidos grasos, influye en su comportamiento y desempeño. Esta investigación, basada en una metodología experimental a través de ensayos de laboratorio, estableció una comparación entre las mezclas asfálticas porosas, empleando para su diseño y producción una, con asfalto puro de penetración 60-70 en 1/10 mm a 25 °C y otra, cuyo asfalto está modificado con amidas de ácidos grasos.Palabras clave: Cemento asfáltico modificado, mezclas asfálticas porosas, mezclas asfálticas en caliente, hidroplaneo, amidas de ácidos grasos, ensayo Cántabro.
