Stabilisation of Road Pavements - Fundamentals

Program Overview

Topics include factors to consider when stabilizing, cement treated basecourse, pavement design principles, and subgrade, sub-base, and basecourse treatment. The course is beneficial for construction managers, supervisors, and road asset managers.

Program Outline

Outline:

This workshop provides an overview of the main issues involved with the design and construction of sealed and unsealed pavements using stabilisation.

Topics include:

• Why, and when to stabilise
• Investigation and testing
• Alternative stabilising agents, lime or cement, bitumen: factors to consider
• Cement treated basecourse
• Pavement design principles
• Planning and economic issues
• Pavement life considerations
• Subgrade, sub-base and basecourse treatment
• Construction basecourse, including compaction
• In-situ stabilisation
• Road rehabilitation, and how stabilisation can help
• Area treatment options
• Use of recycled material
• Seal coat application to stabilised surfaces

Careers:

Construction managers and supervisors will benefit from this course. With the advent of new TNZ performance specifications (B/3 and M/22), there is the opportunity to use alternative materials in conjunction with stabilisation techniques, to meet strength and durability requirements for pavements. On completion of this course participants will:

• Apply the use of material stabilisation to the design and construction of pavements
