Airport Pavement Management Program (PMP) and Airport Signage and Marking Program

Goals: Ensure provision of smooth surfaces with excellent skid resistance devoid of alligator cracks, frost heaving, pumps, ravels, pot holes and wheel rutting which may hinder effectual motion in the airport.

Ensure effectual repair and maintenance of Airport pavements

Ensure proper and clear signage and markings in airports Assumptions and other considerations: It is advisable to submit written suggestions of Airport pavement repairs to the regional Maintenance Engineer who then shares with the Airport Pavement Management Program coordinator in order to ensure good coordination between maintenance and construction initiatives at the airports. Detecting, recognizing and clearly marking runway holding positions and signs in an airport is effectual ...

Introduction

System of road network is needed for any developed country and it is a vital part for infrastructure development. Main subjects of this study are pavement defects such as alligator cracking, bleedings and potholes. Such pavement distress as potholes and alligator cracking cause serious negative effects and decrease the lifespan of pavement. Additionally, the safety on road is questioned due to bleedings of pavement since the friction between car and pavement significantly decreases, meaning that the braking path increases. This study is concentrated on studying ...

- Introduction The subject of this study concerns some of the most serious pavement deficiencies: alligator cracking, bleeding, and potholes. Alligator cracking and potholes can often shorten the pavement’s lifespan. Bleeding more often impacts road safety; bleeding causes reduced friction which, in turn, can cause skidding for drivers. The case study focuses on alligator cracking, potholes, and bleeding in an effort to explain their impact on pavement, as well as how they are remedied. In an effort to better understand the detriment these issues cause, a local two-lane road was studied for evidence of distress and damage. ...

Abstract

Flexible pavement distresses are caused by poor design, wear and tear, and traffic loading beyond design capacity. The amount of loading that a pavement can bear without failure is determined by the strength of the subgrade and the surface layer. Pavement failures are of eight major types; potholes, bleeding, alligator cracking, rutting, shoving, depression, block cracking, and longitudinal cracking. Each pavement distress has causal gents and repair methods defined by local and international codes. This report shall focus on bleeding, potholes, and alligator failure.
