TL;DR: In this paper, a pervious concrete pavement material used for roadway is introduced, which consists of a surface layer and a base layer, and compressive strength of the composite can reach 50 MPa and the flexural strength 6 MPa.
Abstract: In this paper, a pervious concrete pavement material used for roadway is introduced. Using the common material and method, the strength of the pervious concrete is low. Using smaller sized aggregate, silica fume (SF), and superplasticizer (SP) in the pervious concrete can enhance the strength of pervious concrete greatly. The pervious pavement materials that composed of a surface layer and a base layer were made. The compressive strength of the composite can reach 50 MPa and the flexural strength 6 MPa. The water penetration, abrasion resistance, and freezing and thawing durability of the materials are also very good. It can be applied to both the footpath and the vehicle road. It is an environment-friendly pavement material.

TL;DR: In this article, the authors developed a mathematical model to characterize the relationship between compressive strength and porosity for porous concrete by analyzing empirical results and theoretical derivations, which was derived from Griffith's theory.
Abstract: As for many porous media, the strength of porous concrete is significantly affected by the porosity of its internal structure. This paper describes the development of a mathematical model to characterize the relationship between compressive strength and porosity for porous concrete by analyzing empirical results and theoretical derivations. The suitability of existing equations for porous concrete is assessed and a new model is then proposed. The new model, which was derived from Griffith’s theory, presents a better agreement with the experimental data for porous concrete. It is demonstrated that the proposed model could provide a better prediction of porous concrete compressive strength based on the material porosity.

TL;DR: In this article, the authors focused on the balance between permeability and strength properties of polymer-modified pervious concrete (PMPC) mixtures, which included natural sand and fiber to enhance the strength properties.
Abstract: Pervious concrete has been increasingly used to reduce the amount of runoff water and improve the water quality near pavements and parking lots. However, due to the significantly reduced strength associated with the high porosity, pervious concrete mixtures currently cannot be used in highway pavement structures. A laboratory experiment was conducted in this study to improve the strength properties of pervious concrete through the incorporation of latex polymer. This study focused on the balance between permeability and strength properties of polymer-modified pervious concrete (PMPC). In addition to latex, natural sand and fiber were included to enhance the strength properties of pervious concrete. The test results indicate that it was possible to produce pervious concrete mixture with acceptable permeability and strength through the combination of latex and sand.

TL;DR: In this paper, the authors describe how pervious concrete as a paving material has generated tremendous interest because of its ability to allow water to flow through itself to recharge groundwater and minimize storm water runoff.
Abstract: This publication describes how pervious concrete as a paving material has generated tremendous interest because of its ability to allow water to flow through itself to recharge groundwater and minimize storm water runoff. This introduction to pervious concrete pavements reviews its applications and engineering properties, including environmental benefits, structural properties, and durability. Both hydraulic and structural design of pervious concrete pavements is discussed in the publication and construction techniques are also described.
