Problem

Deteriorating Pavements More traffic, trucks, buses

Less funding available Road materials are more

costly

Useful life of materialsseems shorter

will save a minimum of 10 %.

Micro PAVER Provides A Plan that can be explained

Documentation to support the Plan

Reinspection to confirm the Plan is on

track and working Objective before and after comparisons

(responsibility)

A format to test new ideas


19/22

Micro PAVER vs Dump Truck (or resurfaced

street)

The Micro PAVER is an investment in a new

way of solving problems. It provides the documentation to direct and

justify decisions to provide savings.

This is an investment into having a better streetsystem.

The dump truck or resurfacing is gone in severalyears with minimal lasting benefit for the system.


20/22

When Funding is short The Best decisions need to be made

Best treatment - best street - best time More Documentation is needed for

reasonable explanations More public inquires are a certainty

Illustrations of just what is the result willprovide sooner refunding

Be Proactive (somethingcan be done)


21/22

Micro PAVERcan produce

A listing of Streets to be Treated in the next 3 5 years.

Understanding that there are variables that

could modify the list (up or down). Funding, severe weather, material costs, changing

traffic patterns

The list will include: Preventive maintenance, routine maintenance and

severely deteriorated street repairs (good, fair & bad)A Balanced Program
