Description
Technical field
The invention belongs to highway construction construction field, and in particular to a kind of bituminous paving pine laying roughness measurement instrument and survey
Amount method.
Background technology
《Standard for terms used in road engineering》(GBJ124-88) surface evenness is defined as：Road surfaces longitudinal direction concavo-convex amount it is inclined
Difference.At present, the common survey tool of China's surface evenness has：Continous way smoothness measuring equipment, jolt accumulating instrument and 3m rulers etc.
Several method.
The design feature of common survey tool and application：
1. continous way smoothness measuring equipment is eight wheel instrument：Frame that the measuring instrument is grown by a 3m, front and rear respectively there are 4 road wheels
(being commonly called as " eight wheel instrument "), middle measure wheel and data sampling and processing and storage display system composition.Frame can shorten or roll over
Folded, frame interassay wheel can be packed up and put down, and eight wheel instrument rows are detected equipped with displacement transducer, range sensor etc. on measure wheel
Distance and measurement surface evenness are walked, measurement result is represented with standard deviation sigma, in units of mm.Eight wheel instrument have volume and weight
Greatly, the characteristics of needing manpower or vehicle to draw, the flatness on road surface is molded suitable for measure, evaluates the construction quality on road surface and make
Use quality；
2. the accumulating instrument that jolts is vehicle-mounted roughness measurement instrument：Displacement transducer is installed on detection car bottom plate, uses steel wire rope
It is connected with rear axle, the connection of the quantitative displacement wheel of the other end and sensor, when the vehicle is running, road table is uneven makes rear axle for test
The caused relative displacement between compartment, steel wire rope drive quantitative displacement wheel to rotate output pulse signal, and this signal is through computer number
Displacement is converted into according to acquisition process and is recorded.By measuring unidirectional position of the vehicle when being passed through on road surface between rear axle and compartment
Accumulated value reflection surface evenness is moved, accumulation VBI represents measurement result to jolt, in units of cm/km.The accumulating instrument that jolts has
Measuring speed is fast, the characteristics of efficiency high, but needs to be arranged on automobile chassis, the flatness on road surface is molded suitable for measure, is commented
Determine the construction quality on road surface and the comfortableness of validity period.
3. 3m rulers are one three meters long of aluminium alloy meter ruler, by the maximal clearance evaluation road for determining ruler and road surfaces
Surface evenness, in units of mm.3m rulers have small volume, in light weight, the characteristics of being easy to carry.Suitable for determining hot asphalt
The flatness of flatness, seam and structure junction in mixture pavement work progress, to evaluate the construction quality on road surface；
