【Abstract】In this article the greencampus road practice of Shandong JiaoTongUniversity is taken as an example， and somesimple green technical measures in specialregional are summarized such as the road netorganization， the road pavement way， theroad drainage and the road lighting. A campusroad model with the cultural and comfort andharmonious using simple local materials，some common technology and in low cost iscreated. The original campus resource is as faras possible to be protected and utilized. Thenatural environment is less destroyed. Thecampus road is convenient and characteristic.The article is aim to provides some thoughtsand references to other campus road design.

1.Introduce

The campus of Shandong JiaotongUniversity is located in Jinan city. It is about300 aches area. The terrain of the site iscomplicated. There is much different heightand there are a lot of stones and less soil in thisfield. In this project the local conditions aresurvey and measures are adjusted accordingto the local conditions in the design of roadnet organization， the road pavement way，the road drainage and the road lighting.The campus road model with culture andcomfort and harmony is set using simple localmaterials， some common technology and inlow cost.

2.The flow line organization ofthe campus road

The common way to some road plans ofcomplex topography and landform is generallyto turn the ground into a fl at surface fi rst withthe balance of the site soil and then design. Inthis practice we choose different road typesand different road width to meet the differentneeds. Make full use of the three-dimensionalspace increasing the road diversity choice.Organization the flowing lines of cars andpeople according to the site terrain and the sitefeature. Reduce the influence to the originalcampus environment. The road characteristicsare convenient and ornamental. In this way thecampus roads meet the different needs of carsand pedestrian and the extensive managementpatterns are formed and prominent benefi t areachieved.

3.The less surface hardening inthe campus road

Less surface hardening is paved incampus road to meet the essential needs. Adoptnarrower width roads， keep the soil and thegrass directly and set the stone as a step roadand so on.Nowadays the campus road width isgenerally determined according to the roaddesign regulation. And the selected width inmain road is usually about 9.0m to meet thetwo-way lanes. The minimum width is 7.0m.However in some old campus the road widthis generally 6.0m and it usually paved withlocal material. The road scale forms a pleasantspace. So the width of the main campus roadis 6.0m which can intersect for two-way carlanes in Shandong JiaoTong University. Theappropriate width restricts the vehicle’sspeed and reduces the transit frequency.Reduce the emission of CO2. It keeps themajor student activities away from risk andmakes the teaching buildings around awayfrom the noise（ Fig. 1）.Fig.1 the permeability path using originalstoneKeep the soil and the grass directlyas road. It is convenience for use and storethe water. In this project the road before theReport Hall of the Library is the step stoneroad. The stones come from the local site（ Fig.2）. The road surface is formed by stones andthe grass between the stones and stones. Itshows the unique ecological characteristics.The road between the Ecological Walls ofthe Library is paved by the embedded grassbrick. The cushion layer of the road is waterpermeability pavement. The cold seasonalgrass grows into the embedded grass brick. Itintegrates the natural landscape. In this waythe surface water can go through the surfaceand direct infiltrate to underground. The soilmoisture is kept effectively and beneficial tothe plants growth. The snow in permeable roadmelts faster than normal. It is safe which isunfreezing and anti-skid in winter.Fig.2 permeability path using processing localstone
