Be classified it is obtaining as a result, user can be directly acquainted with bituminous pavement emission reduction situation up to standard, it is very simple and clear.
The specific evaluation score computation method of Pavement Evaluation system provided by the invention is described in detail below:
Quantitative parameter analysis unit 62 quantifies quantitative relevant parameter, the quantization method point of quantitative relevant parameter
Three steps: determining the specific intension of index, and Threshold Analysis establishes evaluation function.Consider a variety of different indexs, use is more general
Evaluation function carries out dimensionless processing, eliminates due to unit and numerical value quantity bring negative influence between each index, specific to evaluate
Function is fuzzy membership function, is allowed to fall in [0,100] section multiplied by 100 to its result.
Qualitative parameter computing unit 61 also quantifies qualitative relevant parameter, and qualitative relevant parameter is examined by establishing
Nuclear model quantifies, and each qualitative relevant parameter is decomposed into multinomial examination entry, and assign specific score value, full marks 100
Point, to meet the score value summation of examination entry as the score value of this evaluation index.
The quantized result of the relevant parameter in each stage is as follows:
The planning and designing stage:

It is divided into old road utilization rate multiplied by 100.
The operation management stage
1, the gradient: with the gradient 0~2% for 100 points, maximum longitudinal grade index is 0 point, other situations (2% to maximum longitudinal grade it
Between) fuzzy membership function calculating score is established, wherein the acquisition of maximum longitudinal grade index is related with highway layout speed.Road is set
Meter speed degree: highway (120km/h, 100km/h, 80km/h), Class I highway (100km/h, 80km/h, 60km/h), second level
Highway (80km/h, 60km/h, 40km/h), Class III highway (40km/h, 30km/h), Class IV highway (20km/h).
Required parameter: highway layout speed, road average gradient value.
2, irregularity degree: with irregularity degree RQI=10 for 100 points, RQI=0 is 0 point, establishes fuzzy membership function meter
Calculate score.
Required parameter: IRI.
3, pavement strength
Required parameter: grit level parameter
Score by rules: for grading index with 0 for 100 points, 10.0 be 0 point, establishes fuzzy membership function, is also greater than 10.0
0 point.Grit level parameter calculates as follows:
In formula: GI --- grading index；
Xi--- percent of pass (%) of the 0.45 side's grading curve in sieve pore i；
--- percent of pass (%) of the 0.45 side's maximum size-density line in sieve pore i.
4, mode is maintained
Required parameter: early curing mode (50%), later period maintenance mode (50%).
Score by rules: early curing mode: hot asphalt overlay 74.5 divides, and in-situ heat regeneration 89.5 divides, on the spot it is cold again
94.4 points raw, screening seal coat 82.5 divides, and slurry seal/micro zooming 87.5 divides, and crack sealing 97.5 divides, crack filling 90
Point, mist sealing 93 divides；Later period maintenance mode rebuilds 82 points, and heat mixes large-scale structure and repairs 92, and warm mix large-scale structure is repaired
It is 96 points multiple.
The weight setting method of relevant parameter is as follows:
The weight of relevant parameter is determined using analytic hierarchy process (AHP), steps are as follows:
1) correlation between element is respectively participated in analysis system, establishes the recursive hierarchy structure of internal independence.
2) method for pressing importance scale, by each component of same level relative to a certain principle in a upper level
The property wanted is compared two-by-two, Judgement Matricies.
3) characteristic value and feature vector for solving judgment matrix, detect consistency, determine each layer element according to judgment matrix
Relative weighting.
4) combining weights are calculated using adding combination, obtains final weight of each layer factor under general objective.
A kind of preferred parameter combination weights are as follows:
For certain relevant parameters containing more than two subitem (containing 2), subitem determines power by G1 enabling legislation [80]
Weight, then press weight distribution subitem score.After obtaining the G1 method weight of subitem, total score 100 is divided and is allocated by weight, i.e.,
Each subitem score can be obtained.
Evaluation result stage unit 63 takes the school report the five-grade marking system to be classified evaluation result, according to specifically evaluating
Divide and final result is divided into outstanding, good, medium, qualified, unqualified five grades, specific score value delimitation can specifically be set
It is fixed；It points out the lower relevant parameter item of score simultaneously, is pointedly improved convenient for user.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
