Road Materials and Pavement Design, 2007
ABSTRACT This paper deals with the theoretical and experimental analysis of percolation phenomena of water into Porous Asphalt concretes (PA). The main objects are the following: a) comparison of different indicators dealing with percolation processes; b) finding the best volumetric descriptor of percolation phenomena.

Improvement of Mix Design for Porous Asphalt
Road Materials and Pavement Design, 2001ABSTRACT An improved mix design approach for porous asphalt is presented which is based on the packing theory for aggregate gradation optimisation, thus reducing the post-compaction effects of the pavement by traffic loads. The specimens produced by this mix design method were compared to a Swiss Standard mix from a job site.

Improved durability of recycled porous asphalt
Construction and Building Materials, 2013Abstract Porous asphalt mixtures are extensively used as highway surface layer due to their benefit in improving skid resistance and reducing spray and splash effects during wet conditions. Moreover, porous asphalts (PA) are also oriented towards the reduction of road traffic noise thanks to enhanced sound absorption capabilities.

The Raveling Characteristic of Porous Asphalt Mixture
ICTE 2011, 2011In order to obtain a clearer understanding of the porous asphalt mixture (PAM) raveling characteristic, laboratory Cantabro tests were carried out to evaluate the raveling of long term aged and unaged PAM. The Cantabro test conditions consisted of standard condition, soaked condition, low temperature condition and freeze-thaw condition.

Size is relative. Densely graded sand-asphalts are relatively similar to conventional, bituminous concretes. Porous sand-asphalts possess the same attributes as other porous, bituminous mixtures. Surely, sand-asphalt mixtures, can be designed to be as porous as the so-called, open-graded plantmix seals.

PAVEMENT DESIGN WITH POROUS ASPHALT
2013In this research study, a strategy was used for assigning stiffness values to various layers of the pavement system so that there are negligible tensile stresses in the subgrade and base layers. The stiffnesses of the aggregate base layers were assigned double the values of the corresponding subgrade materials.

Permeability model of porous asphalt mixture
2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011The void parameters such as void radius and void space are determined by image analysis of porous asphalt mixture sample slice through cosmos image analyzing software, so as to set the grid size and the initial inputs for the permeability model of the porous asphalt mixture. The method of Monte Carlo is used to build the permeability model.

Construction Technologies and Architecture
Indonesia is a tropical country with high rainfall, which necessitates pavement with higher void content and good drainage conditions. The quality of road pavement depends on the materials used. One type of asphalt mixture with high void content and permeability but low stability is porous asphalt.

Estimation of permeability of porous asphalt mix
Proceedings of the Institution of Civil Engineers - Transport, 2012A numerical estimate of the permeability of porous asphalt mix has been made taking into account the interconnectivity between the voids. Image processing techniques were employed to study the void structure by physically cutting the sample. The cutting of thin slices of porous asphalt mix (from Marshall samples) using a diamond cutter was found to be
