Description
Technical field
The present invention relates to a kind of covering of roadway structure, be specifically related to a kind of efficient high-grade wide cut road structure internal drainage design.
Background technology
The draining of high-grade highway is most important for traffic safety.The main surface drainage adopted mainly is divided three classes at present, i.e. road surface draining, median strip draining and road structure internal drainage.For high-grade wide cut road surface, adopt road surface runoff draining and median strip draining easily to cause drainage efficiency low, and then the phenomenons such as water drift, neatly occur, affect traffic safety, even lead to traffic accident.Therefore use road structure internal drainage to be the more satisfactory drainage pattern in high-grade wide cut road surface.
France is the country comparatively early carrying out the setting of road structure internal drainage.The seventies and eighties in last century, France built the discharge structure road surface such as Experiment Road, Charles de Gaulle Airport cement concrete road surface in succession, long-term observation result shows that uncured many Void-rich material basic unit can promote the discharge of the inner water leaking-in of road structure greatly, and then prevents the generation of the pavement diseases such as purt mud, faulting of slab ends.The U.S. last century six the seventies carried out a large amount of Pavement Condition investigation, sum up road surface internal construction draining for the very important conclusion of high-grade highway.Bureau of Public Road FHWA just formulated road structure internal drainage design guidelines in 1973.1986, on the summary of experience basis of many decades, the U.S. again further using the drainability of road structure as an index, write into AASHTO(Pavement Structure Design guide).Simultaneously in the developed country such as Japanese, German, drainage pavement build the experience also obtaining a lot of preciousness with the research of road structure internal drainage.
Although road structure internal drainage efficiency is higher, for high-grade wide cut road surface, because road surface road width is wider and vehicle complicated, cause common vehicle different with the requirement of drainage pattern to drainage rates with loaded vehicle.Dolly is because the speed of a motor vehicle is very fast and deadweight is less, and road pavement water film thickness is comparatively responsive, needs the lower safety that just can ensure to drive a vehicle of water film thickness.Cart is because the speed of a motor vehicle is comparatively slow and deadweight is comparatively large, and road pavement drainage rates requires lower, but road pavement requirement for bearing capacity is higher.If full width road surface adopts permeable surface layer to carry out deck draining, then there will be compacted, even to lose drain function situation at loaded vehicle effect lower part permeable surface layer pellet; If full width road surface adopts road surface runoff to carry out draining, then because road width is wider, can cause when amount of precipitation is large and drainage path is long draining not in time, water film thickness becomes large situation.
