Advantages and disadvantages in using permeable concrete as a pavement construction material

摘要: The management of environmental sustainability is increasing importance to the construction industry and its management. One issues with respect impact urbanisation, which results in conversion pervious spaces areas impervious (paved) surfaces, leading a range related problems. A solution use permeable concrete pavements, can be an effective means addressing number supporting sustainable development. Permeable pavements facilitate biodegradation oils from cars trucks, help rainwater infiltrate into soil, decrease urban heating, replenish groundwater, allow tree roots breathe, reduce flash flooding. However, long term behaviour pavement still not well understood. special structural fine particles removed. This creates 15 20% voids. Thus, obtains more voids structure higher water infiltration air exchange rates compared conventional concrete. current constraint development their perceived lack strength. caused mainly by need for greater porosity treatment purposes. paper demonstrates that this material only important contributor practice, but also it can, proper mix design targeted admixtures, achieve reasonable strength as material.
