Materials
This hot-applied material is commonly used to fill cracks in existing asphalt pavements before water can enter and cause further deterioration.
What is crack sealant?
This piece of equipment is commonly used to mow roadside right-of-way vegetation.
What is a mower?
These three letters represent the minimum protective gear required for most TxDOT maintenance activities.
What is PPE?
This maintenance activity restores pavement integrity by filling holes that have formed in the roadway surface.
What is pothole patching?
This license is required for many TxDOT employees who operate large commercial vehicles.
What is a CDL?
This aggregate-based material is commonly placed on unpaved driveways and shoulders to restore shape and improve drainage. (Typically TY A GR1-2)
What is flex base?
This heavy equipment is used to reshape gravel roads, construct crowns, and maintain shoulders and drainage.
What is a motor grader?
This document identifies hazards and controls before work begins and is often discussed during tailgate meetings.
What is a Job Hazard/Safety Analysis (JHA/JSA)?
This repair activity removes vegetation, sediment, and debris from ditches and culverts to improve water flow.
What is drainage maintenance?
During hurricanes, floods, ice storms, and other major events, TxDOT performs this type of response.
What is emergency response?
This petroleum-based binder holds together the aggregates in hot-mix asphalt pavement.
What is asphalt binder (asphalt cement)?
This machine uses steel or pneumatic tires to compact asphalt and base materials.
What is a roller?
This TCP is typically used when performing work on a two-lane roadway that requires the use of flaggers.
What is TCP 1-2b?
This preventive maintenance treatment consists of applying asphalt emulsion followed by aggregate to extend pavement life.
What is a seal coat?
These roadside features help guide motorists at night and during adverse weather conditions.
What are delineators?
This material is often sprayed ahead of seal coat operations to help aggregate adhere to the roadway surface.
What is asphalt emulsion?
This material is used to ensure all equipment used during winter weather operations remains rust and corrosion free and fully lubricated year-round.
What is lubra-seal?
Before excavation activities, employees must contact this system to identify underground utilities.
What is Texas 811 (One Call)?
This pavement preservation treatment uses a mixture of asphalt emulsion, aggregate, mineral filler, and water placed in a thin layer to address oxidation and minor surface distress.
What is a slurry seal?
During emergency operations, TxDOT may implement this traffic management strategy in which all lanes of a roadway are directed away from a threatened area.
What is contraflow?
During pothole repairs, this material can be stockpiled and used year-round without heating, making it useful for emergency repairs.
What is cold mix asphalt?
When maintaining unpaved roads, this motor grader adjustment controls the angle of the blade relative to the direction of travel and directly affects windrow movement.
What is blade pitch (or blade angle)?
TxDOT's safety philosophy that emphasizes every employee returning home safely at the end of the day is called this.
What is Mission Zero?
This type of pavement repair removes the failed asphalt section, repairs the underlying base if necessary, and places new hot-mix asphalt.
What is a full-depth repair?
This pavement preservation concept focuses on making the right repair at the right time before major deterioration occurs.
What is preventive maintenance?
