Department of Transportation El Paso It's All Good

 
 

Street Construction

 

The Department of Transportation is responsible for the maintenance and rehabilitation of the Street right of ways within the corporate limits of the City. The planning and quality control division of the Department administers several contracts for performing work city-wide as well providing inspection and surveying duties in support of these contracts as well as the regular maintenance activities of the Department. In addition to these duties this division also ensures that all departmental projects meet state and federal guidelines for Traffic Congestion Management, Environmental Regulation compliance and the ADA (American with Disabilities Act).

This section is responsible for constructing and repairing the various concrete features within the City right of way.

The parkway structures section works on the concrete elements of the street right of way such as curbs, gutters, sidewalks, bus pads, ADA (American with Disabilities Act) curb cuts, bus stops, pedestrian paths of travel and landings. This section also supports our ongoing maintenance functions by replacing or constructing concrete elements of the roadway as needed.

Improvements within City ROW will follow the guidelines provided in the City of El Paso Design Standards (DSC).

 

This section administers the ongoing street resurfacing operations of the City. These operations vary in size from year to year. This project also makes geometric changes to the street network to improve pedestrian and vehicle movements. Resurfacing projects are coordinated with TxDOT (Texas Department of Transportation), local utilities and the MPO (Metropolitan Planning Organization).

The street resurfacing section is responsible for planning, coordinating and executing each resurfacing project. For each project to be a success local utilities need to be informed to be sure that no projects are planned that will cut the newly paved street. If there are planned utility projects that cannot be completed before the street is to be paved construction of that street may be deferred to a later project. Streets that do not meet current design standards may be deferred to a future Capital Improvement Project for complete reconstruction.

Street resurfacing typically means that the existing asphalt surface of the road will be removed and a new asphalt surface will be placed to the original grade of the street. This process produces material from the old road surface that is recycled into new roadways and fill materials. Asphalt resurfacing is a very “green” process, producing no materials that cannot be recycled, and often incorporating other materials into the mixture like rubber from old tires.

Minor geometric changes to assist storm water runoff may be performed and updating pedestrian paths of travel to meet current ADA (America with Disabilities Act) standards. Other elements of the project include repairing structurally failed curbs, repairing sidewalk that is not passable and installing concrete aprons around any penetrations in the asphalt surface such as manholes, water meters and monuments.

Street Selection Process

Streets are selected for resurfacing based on their condition. Each road segment in the city has a PCI (Pavement Condition Index) score associated with it. These scores are generated by using a program called Micro Paver which was developed by the Army corps of Engineers for managing pavements. The program uses information gathered about the street such as: quantity and type of cracks, patches, potholes, utility cuts and weathering of the surface to calculate the PCI value.

Streets are then ranked according to this value and logical limits of construction are proposed. Typically streets with the lowest scores are scheduled for resurfacing first, however it is possible for a street to have structural issues that require work beyond the scope of the resurfacing program. These streets are submitted to the Capital Improvement Program.

This section provides survey, GIS (Geographic Information Systems) research and drafting support for the Department of Transportation and other City Departments.

The Survey section provides various support activities for the Department of Transportation and other City Departments. These tasks include: researching plats, property, township, verifying property lines, surveying projects, providing elevations, producing plans, creating conceptual drawings and creating presentation materials. These services support Capital Improvement Projects and assist with providing improved geometric layouts to streets and intersections allowing for improved traffic flows and congestion mitigation. These activities allow the City of El Paso and the Department of Transportation to produce a high quality project, weather it is restoring a roadway to allow better drainage, landscaping a median or installing a bike lane.

This section is responsible for several city-wide contracts and new projects, including: Sidewalk inventory, Thermoplastic Striping, Micro-surfacing and Unpaved Rights of Way paving.

The special projects section of the Planning and Quality Control Division handles all other short and long term contract activities. We are responsible for researching, specifying, inspecting and managing these projects. Among the projects that we have recently overseen are Asphalt Rejuvenation, Micro Surfacing, Thermoplastic Street Markings and Paving of Unpaved City Rights of Way.

Asphalt Rejuvenation:
This project is one of the tools in our pavement management system it consists of spraying a rejuvenating agent on an existing asphalt surface to prolong its life by replacing chemicals in the asphalt that fade with exposure to the elements and the passage of time. This program targets streets that are in very good shape in an effort to maintain the condition for longer time periods, thus reducing the overall life cycle cost of the surface. Asphalt rejuvenation is typically a one day process where the rejuvenating agent is applied in the morning and any residue is removed by the end of the workday.

Micro-Surfacing:
This program is a test program for our pavement management system; it consists of adding a thin asphalt overlay to an existing surface. This program is also targeted at streets that are in a relatively good condition to keep them in a high level of service for longer periods of time. The micro-surfacing application will seal the road surface, restore the skid resistance to the surface and extend the life span of the pavement.

Thermoplastic Lane Lines / Markings:
Thermoplastic lane lines are a longer lasting alternative to painting lane lines. Thermoplastic material is literally a colored plastic material that is heated and applied to the road surface. The material may be used for any pavement markings and may be applied in various thicknesses to allow a detectable profile as well.

Unpaved Rights of Way:
The unpaved Rights of Way Project is focused on paving and modernizing the existing alleys throughout the city. Currently, the program has been focused near the mountain areas due to the increased maintenance costs of these alleys. Paving alleys has many benefits ranging from reducing the amount of dust in the air (as per PM-10 and PM-2.5 federal regulations), better storm water management, minimizing illegal dumping, improving ingress and egress and enhancing the esthetics of the surrounding neighborhood. This project re-designs each alley or unpaved road to allow for optimized drainage and protection of the surrounding properties.
