Reconnaissance Needs

1. Determine how many sites (or roadway lengths) will require rehabilitation to improve long-term pavement performance and/or special investigation.

2. Determine updated traffic volume for each Route including heavy vehicular traffic. Confirm estimate with Park Officials.

3. Evaluate performance of previous rehabilitation projects. Determine if pavement treatment will provide necessary restoration for Preventive Maintenance and Light 3R treatments.

Project Summary / Description This project will rehabilitate 17.4 miles of the Entrance Road (Route 10) including the Devil’s Garden Loop at the northern end (0.8 miles, Route 501), 2.1 miles of the Windows Road (Route 11) including 0.6 miles of the Windows Loop Road, the Panorama Overlook Road (0.3 miles), the Salt Valley Overlook Road (0.25 miles), and the Fiery Furnace Road (0.3 miles). The majority of the pavement on these routes are listed in fair to good condition with some spot area shown as poor.

Treatments are subject to change following detailed pavement investigation and analysis.

Explanation of Distress Ratings

Ride Quality‐ Ride quality is based on Roughness, the deviation of a surface from a true planar surface, and is determined using the International Roughness Index (IRI) and measured in inches/mile. This is the primary characteristic dimension that affects vehicle dynamics and ride quality.

Ride Quality:

Good Section average of measured IRI < 170 in/mi.

Fair Section average of measured IRI are between 170 and 240 in/mi.

Poor Section average of measured IRI > 240 in/mi.

Cracking‐ Cracking is based on the extent and severity of transverse, longitudinal and fatigue (alligator) cracking. An index is calculated based on the area of pavement affected by cracking and a severity factor. Severity levels are split into low, moderate, and high. For transverse and longitudinal cracking, severity levels are based on crack widths. For alligator cracking, severity is based on interconnectedness of the crack pattern and spalling.

Cracking:

Good Occasional or no incidence of low severity cracking.

Fair Widespread low severity cracking or occasional moderate severity cracking.

Poor Widespread low to moderate severity cracking or occasional high severity cracking.

Rutting‐ Rutting is based on the average of measured rut depths along a section. A rutting index is calculated based on the frequency of measured rut depths meeting a depth criterion. Like cracking, rutting contains levels of severity (low, moderate and high) based on increasing rut depth.

Rutting:

Good Section average of measured rut depths < 0.25”.

Fair Section average of measured rut depths are between 0.25” and 0.50”.

Poor Section average of measured rut depths > 0.50”.
