Pavement Distresses and Rehabilitation for Circle Drive

Pavement Management is a decision-making process used to make cost-effective decisions about design, construction, maintenance and rehabilitation of pavements. Having a Pavement Management System in place allows for engineers to adequately examine the severity of pavements on freeways, interstates, parking lots, and local roads. To examine the severity of Circle Drive on The University of Texas at Tyler’s campus, the presentation will provide calculations and procedures using the Pavement Condition Index (PCI). This PCI will ensure that pavement section coincides with the initial visual findings, which ranges from 0 (worst) to 100 (good condition). Upon using the PCI, I used the Network Level approach which addresses broad pavement maintenance and rehabilitation questions which then suggests a general idea on the amount of funding needed based on the level of treatment required for Circle Dive. The data gathered from physical field work revealed that the various pavement distresses observed for Asphalt were Alligator Cracking, Longitudinal Cracking, Transverse Cracking, Crack Seal, Block Cracking, Raveling, Reflective Cracking and Low-Grade Fatigue Cracking. Due to Poor Drainage Conditions, there were also distresses such as Water Bleeding and Pumping, Depression Due to Pumping, and Potholes. Since the Pavement distresses range from a low to high severity, the remedy for each case varies. For example, for Alligator cracking of Medium Severity with Low Extent, it will be suggested to patch that portion. In other instances, it will be wise to use solutions such as crack seal, scrub seal or mill & fill for Transverse Cracking. Block Cracking may require the same treatment course as well based on severity. For a typical lane-mile road, usually it is suggested to use rehabilitation measures in certain sections rather than using one method for all distresses, so this research presentation will follow the same suit
