A review of using porous asphalt pavement as an alternative to conventional pavement in stormwater treatment

World Journal of Engineering, 2017
Purpose Porous asphalt has been used for than 50 years, but it was originally developed in 1970 at Franklin institute in Philadelphia, Pennsylvania. By 1974 the first formalized procedure was created by the federal highway administration to design mixtures. Many researches on porous asphalt mixture have been conducted for the past two decades. However,

Optimization on the Sound Absorption of Porous Asphalt Pavement

Key Engineering Materials, 2022
Optimization on Porous Asphalt Pavement is based on noise reduction capacity. The influence factors of sound absorption properties of porous asphalt mixture were studied by using standing wave ratio method.The results indicate that: The peak absorption coefficient of porous asphalt mixture increases with the increase of porosity and the peaks are ...

The Influence of Porous Asphalt Pavement Based on DEMATEL

Applied Mechanics and Materials, 2012
Taiwan position is in the subtropics, the climate is high temperature and much rains of year. Freeway mostly uses traditional dense grade in pavement construction, so the pavement could not remove water quickly in rainy day. It will deteriorate by rutting and aging, due to increasing maintenance frequency and cost.

Laboratory Testing of Asphalt Concrete for Porous Pavements

Journal of Testing and Evaluation, 1981
Abstract Laboratory testing was conducted to determine the effects of aggregate gradation and asphalt content on the stability and permeability of open-graded asphalt concrete. Test results indicate that permeability increases and stability decreases as the aggregate gradation becomes more open-graded, that is, includes less of the ...

Porous flame-retarded asphalt pavement for highway tunnel

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2008
A new way to improve the tunnel fire protection by using flame-retarded porous asphalt pavement containing ATH powders was introduced. Based on the miniature burning test designed and conducted, the burning time and temperature of porous asphalt (PA) and flame-retarded porous asphalt (FRPA) were studied comparing with cement concrete pavement, dense ...

PAVEMENT DESIGN WITH POROUS ASPHALT

2013
In 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.

Mechanical Analysis of Porous Concrete Base in Asphalt Pavement

Advanced Materials Research, 2012
In China, it is fact that porous concrete base has been used in the construction of asphalt pavement in recent years because porous concrete base has good performance. However, Reasonable design method has not been put forward so far. Therefore, it is necessary to analyze load stress and thermal stress of asphalt pavement which includes porous concrete

Development of Structural Design Guidelines for Porous Asphalt Pavement

Transportation Research Record: Journal of the Transportation Research Board, 2018
Porous asphalt pavements allow designers to introduce more sustainability into projects and lessen their environmental impact. Current design procedures are based primarily on hydrologic considerations; comparatively little attention has been paid to their structural design aspects.

Interface treatment of longitudinal joints for porous asphalt pavement

International Journal of Pavement Engineering, 2015
In Germany, multiple lanes of porous asphalt (PA) road surfaces should be constructed with a longitudinal hot joint construction over the full pavement width according to the ‘Technical Instruction for Porous Asphalt Surfacing’. In this way, longitudinal cold joints are avoided and the transverse drainage is not impeded.

Design, Construction, and Maintenance Guidelines for Porous Asphalt Pavements

Transportation Research Record: Journal of the Transportation Research Board, 2001
Oregon has been using open-graded hot mix on its roadway system since the late 1970s. Because of the performance of these early jobs (and the continued good performance of these mixes), open-graded hot mix has been the preferred choice for a surface course on Oregon highways. The following are described with respect to the use of these mixes in Oregon:
