Foreword
This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents"
Drafting:
This document replaces GB/T 26764-2011 "Multifunctional Road Condition Rapid Detection Equipment": Compared with GB/T 26764-2011, except for the structure
In addition to adjustments and editorial changes, the main technical changes are as follows:
a) Added the terms and definitions of car jumping, wear, geometric data and retroreflective brightness coefficient (see 3:6 to 3:9);
b) “Composition and Function” has been changed (see Chapter 4, Chapter 4 of the:2011 edition);
c) Added the compliance requirements for vehicle announcements [see 5:1:1:1d)];
d) Added the requirement that the ground penetrating radar be connected to the carrier vehicle in an integrated structure [see 5:1:1:1e)];
e) The measurement error requirements and test methods of mileage measuring devices have been changed (see 5:1:2, 5:3, 6:4, and 5:2 and 6:5 of the:2011 edition);
f) Added the three-dimensional data acquisition method in the technical requirements of the road damage detection system (see 5:1:4:1);
g) The technical requirements and test methods for road damage identification accuracy have been deleted (see 5:4:2 and 6:7 of the:2011 edition);
h) Added data statistics methods for the flatness, rutting, structural depth, vehicle jump, ground penetrating radar and retroreflection brightness coefficient detection systems
(see 5:1:5:2, 5:1:6:2, 5:1:7:2, 5:1:8:2, 5:1:9:2, 5:1:11:2);
i) Added structural depth and wear detection system, vehicle jump detection system, ground penetrating radar detection system, geometric data detection system and inverse
General requirements, technical requirements and test methods for detection devices and software such as reflection brightness coefficient detection systems (see 5:1:7~
5:1:11, 5:3, 6:9~6:13);
j) The measurement error requirements and test methods for geographic location information acquisition devices have been changed (see 5:3, 6:5, 5:3, 6:6 of the:2011 edition);
k) Added technical requirements and test methods for the minimum resolution width of cracks and the measurement error of pavement damage area (see 5:3 and 6:6);
l) Changed the technical requirements for the measurement correlation coefficient of the rutting detection system (see 5:3, 5:6:1 of the:2011 edition);
m) The test methods for the measurement repeatability test of flatness and rutting, the speed effect error test, and the measurement correlation test have been changed (see
6:7:3~6:7:5, 6:8:3~6:8:5, 6:8:2~6:8:4, 6:9:3~6:9:5 of the:2011 edition);
n) Added the International Roughness Index (IRI) calculation procedure, rutting envelope calculation model and vehicle jump calculation method (see Appendix A, Appendix
B and Appendix D):
