| S.No. | Checkpoint | IS Requirement | Status |
|---|---|---|---|
| A. TEST SETUP AND PREPARATION | |||
| A1 | Test load configuration and distribution Acceptance: Load = design factored load or 1.5× LL; distributed as per standard vehicle/truck configuration | Cl. 8.1 — Load per design load class | OK NC NA HOLD |
| A2 | Loading vehicle specification and weight Acceptance: Vehicle weighed on certified scales; weight distribution documented; braking capability verified | Cl. 8.1 — Vehicle weight verified | OK NC NA HOLD |
| A3 | Deflection measurement instrumentation Acceptance: Dial gauges or LVDT transducers installed; data logger operational; measurement accuracy ±0.5 mm | Cl. 8.2 — Accurate measurement required | OK NC NA HOLD |
| A4 | Measurement point locations and baseline Acceptance: Points at mid-span and quarter-span; baseline recorded without load; no ambient vibration during test | Cl. 8.2 — Points at critical locations | OK NC NA HOLD |
| B. INITIAL LOAD TEST (AMBIENT CONDITIONS) | |||
| B1 | Initial deflection under proof load Acceptance: Deflection ≤ 1.5× theoretical; measured within acceptable limits; load held 30 minutes for creep observation | Cl. 8.2 — Deflection recorded | OK NC NA HOLD |
| B2 | Elastic recovery after load removal Acceptance: Recovery ≥ 90% within 30 minutes; permanent set ≤ 10% of total deflection | Cl. 8.2 — Bridge should recover elastically | OK NC NA HOLD |
| B3 | Deflection profile across width Acceptance: Deflection profile symmetric about centerline; no anomalies indicating local failure | Cl. 8.2 — Load distribution verified | OK NC NA HOLD |
| C. REPEATED LOAD CYCLES | |||
| C1 | Second and third load cycles at full test load Acceptance: Deflections in cycles 2 and 3 ≤ cycle 1 ± 5%; no increasing deflection trend | Cl. 8.2 — Cyclic behavior checked | OK NC NA HOLD |
| C2 | Load retention and recovery in cycles Acceptance: Elastic recovery consistent across cycles; no creep progression; structure behaves linearly | Cl. 8.2 — Stable response required | OK NC NA HOLD |
