Section 6: Super Heavy Load Evaluation Process

The Texas Department of Motor Vehicles, Motor Carrier Division (MCD), will create a proposed route for super heavy loads with GVW over 500,000 lbs. or for tire loads exceeding 6,000 lbs. MCD then submits the proposed route to the customer for review. If the customer accepts the proposed route, MCD submits a letter, including the proposed route, load configuration diagrams, and proposed move dates, and control section numbers to MNT – Pavement Asset Management. MNT – Pavement Asset Management reviews proposed route using the data and information supplied by MCD and evaluates the pavement condition using PMIS distress and condition scores. The proposed route is submitted to the affected TxDOT districts for review. The districts are given three business days to complete their review. MNT – Pavement Asset Management may conduct additional testing as needed, using data supplied by the affected district (pavement typical sections, visual distress evaluation, FWD deflections, and construction information). Based on the analysis, MNT – Pavement Asset Management provides MCD recommendations on the proposed route. Figure 13-3 shows the flow chart of the super heavy load evaluation process.
