FLEXIBLE PAVEMENT IN METRO MANILA SKYWAY
WHAT IS FLEXIBLE PAVEMENT? ďƒ˜composed of a bituminous material surface coarse and underlying base and subbase courses.
ADVANTAGES: Adaptability to stage construction Availability of low-cost types that can be easily built Ability to be easily opened and patched Easy to repair frost heave and settlement
DISADVANTAGES: Higher maintenance cost Shorter life span under heavy use Damage by oils and certain chemicals Weak edges that may require curbs or edge devices
THICKNESS DESIGN: Several procedures are used based on volume and weight of traffic Load supporting capacity of soil is important Heavy vehicle wheel load has greater impact
THICKNESS DESIGN: Traffic analysis in necessary designs are chosen based on: • Designed traffic in terms of cumulative numbers of standard axels • CBR value of subgrade
TOTAL THICKNESS OF PAVEMENT:
PAVEMENT DISTRESS Pavement distress refers to the condition of a pavement surface in terms of its general appearance.
TYPES OF DISTRESSES: Alligator Cracking
TYPES OF DISTRESSES: Bleeding
TYPES OF DISTRESSES: Block Cracking
TYPES OF DISTRESSES: Depression
TYPES OF DISTRESSES: Longitudinal Cracking
TYPES OF DISTRESSES: Transverse Cracking
TYPES OF DISTRESSES: Patching
TYPES OF DISTRESSES: Potholes
TYPES OF DISTRESSES: Rutting
TYPES OF DISTRESSES: Raveling
PROBLEMS AND SOLUTIONS  Clogged exit(Filinvest Exit) -Road widening in Filinvest exit: decongested the traffic since the vehicles will exit in Sucat and Alabang exits going to South Luzon Expressway(SLEX).
PROBLEMS AND SOLUTIONS  SLIPPERY PAVEMENT
-Speed limits are strictly implemented.
PROBLEMS AND SOLUTIONS ďƒ˜ Collisions and Over Speeding -Installation of 43 CCTV cameras in Skyway stage 1. This cameras are viewed in real-time and are connected to the Central Control System to properly monitor the traffic and the emergency situations in the Skyway
