By taking 328 provincial highway overhaul engineerings as an example：
Old road overview：328 provincial highway Huaian section is located on the south main irrigation canal, is east-west, is Huaian area Qu Nan sections weight
The arterial highway wanted.Standard path be Plain rolling terrain Class II highway, desin speed 80km/h, road surface 14m wide, roadbed 15m wide,
Dirt road shoulder breadth 0.5m.
This maintenance section is located on the embankment of main irrigation canal southern side, and the depth of fill is very high, and old road is 5m letters wide before 2000
Easy asphalt concrete pavement, width of subgrade is 8m；City's highway division carries out widening and improving to old road within 2000, enters in old road southern side
Row half range is widened, and road surface structare layer is during transformation：4cm particulate formula bituminous concrete+6cm Coarse Graded Bituminous Concretes+pitch envelope
Layer+20cm two-ash broken stones+20cm12% rendzinases；Roadbed treatment：70cm scarifyings 20cm is excavated on old road and mixes 6% lime in old road position
, to road surface structare layer bottom, the roadbed 80cm of the newly-built widened section in old road southern side is using at 6% rendzinas for treatment+20cm6% rendzinases
Reason.
By the use of more than ten years, occur the serious diseases such as substantial amounts of vertically and horizontally crack, cracking, depression, repairing on road surface
There is more longitudinal crack more long in evil, particularly road north of a road half range, and the situation of land subsidence occurs in serious section north half range,
Cause serious longitudinal crack occur along road-center, stitching portion generates obvious relative settlement.City's highway maintenance department is more
The secondary position serious to disease is repaired, with the performance of road improvement.But it is because this section heavy-duty vehicle is more and super
Carry that phenomenon is universal, old road part roadbed treatment is weaker, and road breakage is very serious, to vehicular traffic and pedestrian with
Inconvenience and potential safety hazard are come, road surface can not meet the use requirement of existing highway.
Engineered thinking：What the disease that old road produces was caused mainly due to roadbed reason, thoroughly processing scheme is needed
Subgrade of old road is processed, but excavated volume is larger, and scarce side's amount is larger, and difficulty of construction is big, and traffic organization is more difficult, and cost
Height, while may not necessarily also obtain preferable effect.Old road maintenance is advocated and utilizes old road material as far as possible, is economized on resources, environmental protection；
