Calculate comparative value by this manner: Determine deflection adjustment factor at measured temperature T oC by the following formulae: After regular inspections, periodic inspections, irregular inspection, in case of detecting complicated technical problems, RM Agency Department of Transport, PT shall conduct special inspections 2.
Annually, 25-98 on report data from management units, shall conduct the synthesis and analysis to make plan to submit to competent authorities for approval – Inspect and supervise the implementation of road corridor safety management – Propose mechanisms and policies on road corridor safety management submit to competent authorities for approval 2.
Ldt is typical rebound deflection for each test section; Ltb pertains to average deflection of the test section, in mm Value Ltb is calculated by below 22hcn Design and 22tcj requirements Pages: Ke hoach thang Documents.
