dc.description.abstract | In response to global climate change,to address the burden of the drainage system caused by heavy rains,permeable pavement do for a Soothing Solutions,but related research proposed permeable pavement used in multi-light traffic areas,not yet widely used in general traffic of urban roads;and is currently base course of permeable pavement material for yet one full of normative guidelines. Therefore, the study first discusses recycled concrete aggregate used in permeable pavement characteristics;Recycled materials were used followed by graded gravel and permeable concrete to assess its effectiveness in two forms,recycled materials used to explore the suitability of the base course in permeable pavement,this study is to provide a better proportionality of the proposal,to meet the demand of bearing capacity in road works and achieve the effectiveness of water contained and permeability in permeable pavement.
The results showed that use of recycled aggregate concrete at C-40 graded gravel CBR value range can meet its current construction specification for 02726(graded aggregates graded gravel base)the general base course the recommended 80 or more,while permeability coefficient and also meet Japanese permeable paving the recommended 10-3 cm/sec or more,by selector drawings can be find the designed dry unit weight to meet the demand of the base course of permeable pavement.The study of the production of recycled uniaxial compressive strength of porous concrete is 7.4 kgf/cm2 (105.7 psi) ~ 82.1 kgf/cm2 (1172.8 psi),but the proportion of cement aggregates 1:12’s group has been unable to meet the construction specification chapter 02794 (permeable pavement) permeable concrete requirements,they can not meet the Ministry of Transportation road construction specifications for cement treated granular soil condition,the lower the proportion of cement aggregates should pay particular attention in the selection. Finally,according to the study of the process and test results,explore and recommend changes for construction specifications chapter 02794,to make specification more perfect, easy to use engineering reference. | en_US |
