Description
Technical field
The invention belongs to lane detection technology fields, more particularly, to a kind of road evenness detection device and its detection side
Method.
Background technique
Surface evenness refers to the deviation of the concavo-convex amount of road surfaces longitudinal direction.Surface evenness is evaluation pavement quality
One of the key technical indexes, it is related to the safety of driving, the size and service life of impact force suffered by comfortable and road surface, no
Smooth road surfaces will increase car resistance, and so that vehicle is generated additional this effect of vibration of effect of vibration and will cause driving
It jolts, influences the speed and safety of driving, influence the comfortable of the steady and passenger driven simultaneously, effect of vibration can also road pavement
Apply impact force, to aggravate the damage on road surface and automobile parts and the abrasion of tire, and increases the consumption of oil plant moreover, right
In being located at dense waterway net region, the road surface of out-of-flatness can also stagnate rainwater, accelerate the Water Damage on road surface therefore, in order to reduce vibration punching
Power is hit, running speed is improved and promotes road-ability, safety, road surface should keep certain flatness.
Influencing surface evenness factor can involve design, construct, the every aspects such as natural conditions, excellent evenness of road surface
Degree, will rely on excellent construction equipment, and fine construction technology and often and timely conserves stringent quality control on construction
Factor to guarantee that influences Bitumen Concrete Pavement Smoothness mainly has: differential settlement, Paving Techniques, compaction technology are horizontal to connect
Seam processing, mix-design, sub-layer disease etc..
Flatness directly reflects the comfort level of vehicle driving and the safety on road surface and service life.Surface evenness
Detection can provide important information for policymaker, enable policymaker for road surface maintenance, conserve and overhaul etc. and make Optimal Decision-making.
On the other hand, the detection of surface evenness can accurately provide the information of construction quality of pavement, provide a matter for pavement construction
Measure the objective indicator of evaluation.
