Abstract


With the rapid development of China 's transport services , road network construction is maturing , and the rapid growth of the national economy and regional economy . At the same time , the traffic noise and traffic safety issues are becoming increasingly serious . Porous cement concrete material by virtue of its a unique skeleton gap structure , with good noise reduction and drainage performance . Therefore , the study of porous cement concrete pavement materials and their structure has a certain theoretical and practical significance . Start from the drawbacks of traditional concrete pavement and analysis of domestic and foreign research and application of porous cement concrete pavement , summarizes the existing research results and shortcomings , raised the problem of porous cement concrete material applied to the pavement surface . Technical nature of raw materials and test methods for porous cement concrete pavement study proposed on the vibration interior molding process . Porous cement concrete mix than the strength and porosity of the design specifications , porous cement concrete mix proportion design parameters , design principles and steps . The mechanical properties of porous concrete , sound absorption properties , shrinkage performance , permeability and its influencing factors , a series of analyzes , and provides the basis for the porous cement concrete pavement design parameters . On the road carrying capacity and functional analysis , using the composite porous concrete pavement structure . Mechanical requirements should be met from the road and drainage , noise reduction requirements, complete porous cement concrete pavement structure design method . Finally, through the porous cement concrete pavement construction techniques in conducting research using the \
