KDOT Winter Maintenance & Operations 4

Question 1

What should a KDOT inspector verify when conducting a winter maintenance equipment pre-trip inspection?

Accepted Answer

Plow hydraulics, spreader calibration, lights, and fluid levels

Answer

A thorough pre-trip inspection covers plow hydraulic function, spreader calibration, all lighting, fluid levels, and safety equipment to ensure reliable winter operations.

Question 2

How does KDOT's Maintenance Management System (MMS) support winter operations?

Accepted Answer

It tracks material usage, labor hours, and equipment activity for cost accounting

Answer

MMS records labor, equipment, and material data to track winter maintenance costs and support performance reporting and budget management.

Question 3

What is the significance of pavement temperature versus air temperature in winter maintenance decisions?

Accepted Answer

Pavement temperature is the critical factor because it determines whether ice will form

Answer

Pavement surface temperature determines ice formation potential; air temperature can be above freezing while the pavement remains at or below 32°F.

Question 4

Which type of storm requires the most aggressive KDOT winter maintenance response?

Accepted Answer

A freezing rain event with ice accumulation on pavement

Answer

Freezing rain creates a bond between ice and pavement that is extremely difficult to remove and can paralyze traffic rapidly, requiring aggressive pre-treatment and response.

Question 5

What is 'material carryover' in the context of de-icing applications?

Accepted Answer

Residual chemical remaining on pavement from a previous application that continues to work

Answer

Material carryover refers to residual de-icing chemical left on the road that remains active and can reduce the need for additional applications.
