Behavior of Reinforced Pervious Concrete Structures Subjected to Repeated Loading(2/2)

In response to the currently governmental promotion on the energy saving and carbon reduction policies, the traditional civil engineering research is then moved towards the innovation and development of new materials and new methods. Green concrete: storing carbon dioxide in cement, which is part of an annual list of what we believe, is one of the 10 most important emerging technologies 2010 published by MIT in technology review. Nowadays, the sustainable and green building techniques have become major topics in Taiwan. The study of suitable design of pervious concrete structures is an important issue in terms of reducing rainwater runoff, preserving ecological system and mitigating the heat island effect.At present, most of the pervious concrete are limit to be used as a light-vehicle pavement or parking lots. The concrete slabs on the ground is only designed to a pure concrete structure without reinforcing materials. To be considered for a wide application, like to the heavy-vehicle pavement or sewer cover, it is necessary to design the pervious concrete slabs strengthened with reinforcing bars. Moreover, no design code for the pervious pavement can be referred, and the related researches are few. Therefore, the main purpose of the research is to study how to design the pervious concrete slab with reinforcement, in which the design parameters will be considered experimentally by the effect of long-term truck load. The research project is thus proposed for a period of two years. In the first year, the behavior of the pervious concrete subjected to the repeated loading as the traffic load effect is mainly studied. The design parameters of the reinforced pervious concrete (RPC) structures are discussed. In the second year, the fatigue loading tests on several RPC slab specimens designed in accordance with the first year results will be performed.
