At the February 12th Town Board study session, Public Works presented the 2019 Street Improvement Program. This program was developed with the assistance of a piece of software called PAVER which uses a variety of tools to help decide the best treatments for each road at the right time. By utilizing a blend of preventative maintenance (crack sealing, pothole patching, seal coats) and structural work (overlay, mill and overlay, reconstruction), Public Works intends to reverse the downward trend of our road conditions.
2024 Pavement Management Plan
At the February 23, 2016 Town Board study session, Public Works presented the 2024 Street Improvement Program. This program was developed with the assistance of a piece of software called PAVER which uses a variety of tools to help decide the best treatments for each road at the right time. By utilizing a blend of preventative maintenance (crack sealing, pothole patching, seal coats) and structural work (overlay, mill and overlay, reconstruction), Public Works intends to reverse the downward trend of our road conditions. The charts below show the budget distribution of the 1A tax dollars in this program, and how the Pavement Condition Index (PCI) of Estes Parks roads will increase from a value of 65 in 2016 to a value of 73 2024.

Preventative maintenance is a huge part of the 2024 STIP plan and is defined as a planned strategy of cost-effective treatments to an existing roadway system and its appurtenances that preserves the system, retards future deterioration, and maintains or improves the functional condition of the system (without significantly increasing the structural capacity). Preventative maintenance keeps good roads in good shape and, as the table below indicates, keeps costs form maintenance down.
Water is the most destructive element to our pavements, and most of the treatments and techniques utilized are designed to address this issue. Cracks in pavements allow moisture to penetrate the surface which causes pavement material failure. Failure to seal cracks results in further cracking, potholes and eventually a major pavement breakdown, leading to unnecessary expensive repairs. Below, are some of the treatments and techniques that Public Works uses to treat our roads. For information on pothole repair, visit our Pothole Patching Page.
Cracks are sealed with a hot polymer/rubberized liquid asphalt to minimize water infiltrating the pavement base. Crack sealing is an extremely economical way of maintaining pavements. It is very cheap and effective when compared to undertaking other more extensive work such as resurfacing and reconstruction.
Chip sealing is the application of crushed aggregate or gravel (chips) over an emulsified asphaltic oil. The oil seals the street from water penetration while the chips provide a wearing surface for traffic. Chip sealing is a preventive maintenance treatment that rejuvenates old asphalt and creates a new riding surface.
Slurry sealing is the application of emulsified asphalt (a mixture made from oil and fine sand aggregate) to an existing pavement. This treatment also seals the street from water penetration. Slurry sealing is a preventive maintenance treatment that extends the life of pavement while providing a smooth new riding surface.
An asphalt overlay generally consists of placing a new layer of asphalt pavement material over and existing pavement. Preparatory work such as asphalt patching, edge milling and utility adjustments should be completed prior to any overlay work. Overlays are less expensive than complete street reconstruction and result in smoother and stronger pavement.
