High Strength Pervious Concrete
Pervious concrete is increasingly being utilised in the construction of driveways, parking lots, and pavement in many industrialised nations. Testing must be done to assess the performance of this new kind of high-performance concrete in order to establish material specifications for pervious …

Freeze-Thaw Durability of Pervious Concrete
Although the use of pervious concrete is expanding, only a limited number of scholarly papers have been published on the resistance of pervious concrete to deterioration under frost action. Based on this need for additional research on the durability of pervious concrete in cold regions, the …

Hydraulic design of pervious concrete highway shoulders
… in this thesis presents the option of using pervious concrete in highway shoulders as a best management practice for stormwater management. Research focused on the hydraulic response of pervious concrete pavements exposed to sheet flowing water. Pervious concrete samples were placed in a …

Attainable Compressive Strength Of Pervious Concrete Paving Systems
The pervious concrete system and its corresponding strength are as important as its permeability characteristics. The strength of the system not only relies on the compressive strength of the pervious concrete but also on the strength of the soil beneath it for support. Previous studies indicate …

Pervious Concrete: A Hydrologic Analysis For Stormwater Management Credit
Portland Cement pervious concrete's ability to permit water infiltration has encouraged its use as a stormwater management tool. However, the material has suffered historically poor support due to a number of factors, including failures due to poor mix design and improper construction techniques, …

Hydrologic Mass Balance Of Pervious Concrete Pavement With Sandy Soils
Use of pervious concrete pavement as a method of stormwater management has shown great promise in previous studies. Reduction in runoff, water quality improvements, and long-term economic benefits are but a few of its many advantages. Regulatory agencies such as the St. Johns River Water Management …

A study on the debris found in a pervious concrete sample
… to determine how and what debris clogs well-aged pervious concrete, a fourteen-year-old pervious concrete parking lot was cored and the samples investigated. First, a falling head test was performed to determine the infiltration rates on the samples, and the distribution was such that the …

The effects of utilizing silica fume in Portland cement pervious concrete
… the aggregates surface. Because Portland Cement Pervious Concrete (PCPC) has a smaller bond area between aggregate and paste, silica fume has significant impacts on the properties of the PCPC. The research in this paper studies the workability of a cement paste containing silica fume in addition …

Analysis Of Pervious Concrete As A Stormwater Management Tool Using Swmm Modeling
… flows over the ground. Increase in impervious land cover due to urbanization causes excess stormwater runoff and affects the quantity and quality of water bodies. The use of low impact development (lid) controls is highly recommended to reduce the excess volume of stormwater runoff. …

Modification and performance of activated carbon for CO2 sequestration in pervious concrete
… associated with cement and concrete production. Pervious concrete, a class of porous concretes, has been developed as a sustainable form of concrete that can be used for a wide range of applications. Its use is considered a ‘Best Management Practice’, recommended by the Environmental Protection …

Development of a Hydrologic Model for an Urban Headwater Stream: The Influence of Pervious Surface Properties on Runoff Dynamics
… (over 90% developed, and almost 50% impervious surface area (ISA)). Selected datasets provided information on the stormwater drainage network, the physical attributes of the catchment and receiving waterway (i.e. drainage area, slope, etc.), infiltration potential of soil map units, …

Tapetes impermeabilizantes a montante de barragens sobre aluviões permeáveis
… principal solutions for of seepage control on pervious dam foundations. The Finite Elements Method (FEM) was used for the verification of blanket dimensioning methods. Various simulations were undertaken via FEM with the use of two fictitious dams. The blanket dimensioning methods were verified …

Hydrologic calibration of the Cub Run Watershed using the PC version of the Hydrological Simulation Program - FORTRAN (HSPF)
… in the calibration when considering just a pervious segment or two segments (one pervious and one impervious) could be noted, indicating the importance of considering impervious surfaces for the simulation. HSPF reacted quite logically to variations in the calibration parameters and the …

The effect of rainstorm movement on urban drainage network runoff hydrographs
… watershed indicates that rainfall infiltrated to pervious areas might contribute to direct runoff hydrograph, thereby offering an explanation for the long hydrograph tail. Width functions are obtained from urban drainage networks and applied to obtain distinct response functions for Direct …

Exploring the response of urban storm sewer system to the implementation of green roofs
… to allow the overland flow to be routed from impervious to pervious areas. A mathematical model was developed to simulate the major processes affecting the hydrologic response of green roofs (ponding, infiltration, drainage, and recession). The green roof model was calibrated to match the runoff …
