PAVEMENT CONDITION REPORT 2018 MAINTAINING ROADS IS A LOT LIKE MAINTAINING A VEHICLE. IF YOU DON’T PERFORM THE INEXPENSIVE, ROUTINE OIL CHANGES, TIRE ROTATIONS, AND INSPECTIONS, YOU WILL END UP HAVING TO MAKE A COSTLY MAJOR REPAIR OR REPLACE THE VEHICLE ALTOGETHER.

This large highway network is a significant public asset and is used by hundreds of thousands of automobiles, buses, trucks, bikes, and pedestrians daily. Highway surfacing represents the largest capital investment in any modern highway system. Maintaining and operating pavements on a large highway system typically involves complex decisions about how and when to resurface or apply other treatments to keep the highway performing and operating costs at a reasonable level. To achieve this, the Department of Public Works has utilized a Pavement Management Program (PMP) for many years. In order to determine the health or condition of the streets, a standard called the Pavement Quality Index (PQI) is used. The PQI is a scale from 0 to 100, with zero being a pothole- riddled street and 100 a newly surfaced street. In 2018, El Paso County’s streets had an average PQI of 68, which is considered to be in “Fair” condition. There are significant financial implications to PQI. Pavements deteriorate over time. The deterioration is slow at first, but then accelerates when the PQI drops below 70. As the pavement deteriorates, the cost of repair also increases rapidly. Maintaining roads is a lot like maintaining a vehicle. If you don’t perform the inexpensive, routine oil changes, tire rotations, and inspections, you will end up having to make a costly major repair or replace the vehicle altogether. The same is true with respect to roads. If you defer routine preventive maintenance due to inadequate funding, roads will continue to deteriorate, leading to repair backlogs. If there is insufficient funding to maintain streets in their current condition, the unfunded backlog will grow rapidly in 04 the future. The unfunded backlog consists of pavement repairs that cannot be performed due to inadequate funding. This includes street maintenance, rehabilitation, and reconstruction activities. Deferring maintenance to future years will result in higher costs, as streets that need to be overlaid for construction later. Pavement age is just one factor in today’s pavement condition; traffic levels, the underlying subgrade soils, drainage flows, and past maintenance practices are also contributing factors. Consequently, it is not always possible to implement a “one size fits all” approach to maintenance. Each highway segment will have different funding and maintenance needs. The County faces significant challenges in the future for providing adequate roadway conditions. The pavement condition is, as noted, in “fair” condition and will continue to deteriorate very quickly. Three alternate funding scenarios were performed to determine potential outcomes. The analyses indicate that the County needs an average of $36.4 million annually for the next 10 years for pavement maintenance in order to eliminate pavement deficiencies and improve the average network PQI to 81. By doing so, streets can be maintained in good condition with on-going preventive maintenance. Conversely, maintaining the County’s projected funding level (average of $10 million/year) will result in a decrease of the network PQI to 52 over the next 10 years and the unfunded backlog increase to $244 million by 2028. More than ever before citizens are demanding accountability from their local governments. It is unlikely that traffic levels will decrease in the future or that pavements will get so good that they never need repair. Similarly, it is unlikely that major increases in funding for transportation will occur in the near future. Information from a pavement management program provides an effective way to get better performance with less cost by providing valuable information to the appropriate decision-makers. 05 BACKGROUND El Paso County's transportation network consists of more than 2,100 centerline miles of public roadway, ranging from major thoroughfares in urban areas to rural gravel roads and neighborhood streets and cul-de-sacs. El Paso County Department of Public Works maintains over 1,100 centerline miles of paved roads, which equates to over 2,300 lane miles. 225 of the 1,100 centerline miles are chip sealed. Centerline miles include both sides of the road, whereas lane miles are the individual lanes (2 or 4 lanes depending on the road). The road network is one of the most critical assets owned and maintained by El Paso County. Our roads make a significant contribution to the economic vitality of the region. They are a gateway for residents to go to work, take their kids to school, or go shopping. Visitors travel our roads to enjoy the beautiful scenery, outdoor adventures, and all that El Paso County has to offer. El Paso County is committed to a safe and efficient road network through cost-effective maintenance strategies that preserve and improve new and existing roads while delivering innovative and sustainable infrastructure and services. To accomplish this, El Paso County implemented a Pavement Maintenance Program to preserve and extend the life of paved roads while maximizing the use of limited funds and resources. Since 1997, the Public Works Department utilizes the pavement management system Stantec Consulting’s Road- Matrix Pavement Management Application (PMA) software. A qualified and experienced consultant periodically gathers the data on the road conditions using automated sensors mounted to a vehicle that provides updates to the County, which allows staff to evaluate current conditions with its Road-Matrix Pavement Management Software (PMS). PMS software programs model future pavement deterioration due to traffic and weather and recommend maintenance and repairs to the road’s pavement based on the type and age of the pavement and various measures of existing pavement quality. 06 PROGRAM GOALS RESEARCH HAS These goals can be achieved by efficient management SHOWN THAT of maintenance strategies and resources.

Visual data was analyzed on 2,073 lane miles of gravel roads. Information gathered included the Surface Distress Index (SDI) and the Ride Condition Index (RCI), which are used to calculate the Pavement Quality Index (PQI). The Pavement Condition Index (PCI) provides a numerical rating for the condition of road segments within the road network, where 0 is the worst possible condition (impassible), and 100 is the best (perfect condition). To graphically depict the PQI value, we use the nationally accepted ASTM 6433, Standard Practice for Roads and Parking Lot Pavement Condition Index Surveys Pavement Condition OF THE TOTAL 2,321 LANE- Index (PCI) chart. LENGTH MILES OF EL PASO COUNTY ROADS, 653 MILES (28%) DO NOT MEET THEIR The PCI tells public works officials the current condition of a MINIMUM PCI. road and the anticipated rate of deterioration of that road over time. The PCI values are used in prioritizing, funding, and executing maintenance and rehabilitation programs. THE PCI IS A 0-100 RATING SCALE BASED ON THE PHYSICAL AND STRUCTURAL CONDITION OF A ROAD. PQI SCORES OF 70 TO 100 ARE CONSIDERED “SATISFACTORY OR GOOD." THESE ARE NEWLY BUILT OR RESURFACED ROADS THAT SHOW LITTLE OR NO DISTRESS. PQI SCORES OF 50 TO 69 ARE CONSIDERED “FAIR,” WITH ONLY SLIGHT OR MODERATE DISTRESS, REQUIRING PRIMARILY PREVENTATIVE MAINTENANCE EL PASO COUNTY ROADS 68 HAVE AN AVERAGE PQI OF PQI SCORES OF 25 TO 49 ARE CONSIDERED “POOR OR VERY POOR,” 68, WHICH IS CONSIDERED AND ARE WORN TO WHERE RESTORATION MAY BE NEEDED TO IN “FAIR” CONDITION. PREVENT FURTHER DETERIORATION. PQI SCORES OF 0 TO 24 ARE CONSIDERED “SERIOUS OR FAILED” AND MAY REQUIRE FULL RECONSTRUCTION. 08 ROAD CLASSIFICATION El Paso County is comprised of three different road classifications such as arterials, collectors and residential (local). ARTERIALS Arterials are connecting roads such as highways, freeways, and motorways. They handle a large volume of freight and passenger vehicles and are characterized by higher speeds, more trucks, buses, and automobile traffic, and typically have four lanes or more. Of the 284 lane miles of arterial road, 231.6 ARTERIAL ROAD miles are above standard, 17% do not meet the MERIDIAN RD, PQI 70 70 PQI desired minimum.
