Study Notes

Code of Practice for Bituminous Mix Designs

Scope

Covers the process of registering bituminous mix designs to comply with Department of Transport and Planning (DTP) Standard Sections for Roadworks and Bridgeworks
Applicable to various types of bituminous mixes, including Stone Mastic Asphalt, Regulation Gap Graded Asphalt, Dense Graded Asphalt, Open Graded Asphalt, and more

Bituminous Mix Description

Stone Mastic Asphalt (SMA): gap-graded wearing course mix with high proportion of coarse aggregate and polymer modified binder (PMB)
Regulation Gap Graded Asphalt (RGGA): asphalt course applied to adjust pavement surface shape
Dense Graded Asphalt (DGA): mixture of coarse aggregate, fine aggregate, filler, and bitumen, used for wearing and regulation courses
Open Graded Asphalt (OGA): bituminous wearing course mix with high air voids, used for noise and water spray reduction
High Binder Crumb Rubber Asphalt (HBCRA): dense graded asphalt mix with crumb rubber and high binder content
Light Traffic Crumb Rubber Asphalt (LTCRA): dense graded asphalt mix with crumb rubber for use on light trafficked roads
Microsurfacing: bituminous slurry surfacing with polymer modified emulsion binder

Mix Design

Mix designs must comply with requirements of respective Standard Sections
Dense Graded Asphalt (DGA) mix designs can use Austroads Mix Design Method or Marshall Mix Design Method
Open Graded Asphalt (OGA) mix designs must comply with Section 417
High Binder Crumb Rubber Asphalt (HBCRA) and Light Traffic Crumb Rubber Asphalt (LTCRA) mix designs must comply with Sections 421 and 422, respectively

Mix Registration

Applications to register a bituminous mix must be submitted to ARRB with required information at least two months prior to supply
Mixes shall be current at the time of supply and have a unique identification number
Registration status can be 'GENERAL' or 'CONDITIONAL', and remains current for three years
Registered mixes can be de-registered if handling or field performance is unsatisfactory

Information Required for Mix Registration

Dense Graded Asphalt (DGA) mix registration requires information on grading test results, proportion of components, mix properties, and more
Additional information is required for mixes using Warm Mix Asphalt (WMA) technology or other additives
Mixes containing Recycled Asphalt Pavement (RAP) require additional information on RAP nominal size, binder content, and RAP Management Plan### RAP Binder Characterisation and Viscosity Adjustments
RAP binder characterisation and binder blend viscosity adjustments must be designed according to Section 407 Clause 407.13(e)
Table 4 outlines the permitted RAP content (%) by mass for different asphalt types

Table 4: Permitted RAP Content

Type L: up to 25% RAP content
Type N: up to 10% (for C320 binder) or up to 25% (for C170 binder) RAP content
Type H: up to 15% RAP content
Type SI: up to 15% RAP content
Type SS: up to 15% RAP content
Type V: up to 15% RAP content
Type SF: up to 15% RAP content

Use of Recycled Plastic

Recycled plastic can be used in DGA (excluding mixes containing PMB) subject to additional testing and validation
Recycled plastic must be sourced from waste plastic generated in Australia and processed by an accredited supplier
Recycled plastic use will be registered as 'GENERAL' or 'CONDITIONAL' by DTP

Bituminous Mix Registrations

Stone Mastic Asphalt: refer to Section 404
Regulation Gap Graded Asphalt: refer to Section 405
Open Graded Asphalt: refer to Section 417
High Modulus Asphalt (EME2): refer to Section 418
High Binder Crumb Rubber Asphalt: refer to Section 421
Light Traffic Crumb Rubber Asphalt: refer to Section 422
Microsurfacing: refer to Section 427

Test Properties for Bituminous Mixes

Dense Graded Asphalt

Grading of Aggregates: proportions of aggregate and binder in the mix, including any added filler, must lie within the limits specified in Table 5
Table 5 outlines the grading limits for aggregates (including any filler)
RAP must comply with the requirements of Section 407
Minimum Design Binder Content: binder content must comply with the requirements of Table 6
Binder Film Index: binder film index must comply with the requirements of Table 7
Added Filler: wearing course asphalt must contain a minimum of 1% added filler

Volumetric Test Properties

Austroads Mix Design Method: laboratory compaction level and design air voids for all mixes must comply with Table 8
Marshall Mix Design Method: test properties for mix types must comply with Tables 7 and 9
Voids in Mineral Aggregate (VMA) and Binder Film Index: minimum limits specified in Tables 7 and 9
Type HP and SP: design binder content and volumetric properties derived from complying Type H and SI mixes

Performance Test Properties

Indirect Tensile Modulus Test

Mean indirect tensile modulus of test specimens for each asphalt type must be within the specified range in Table 10
Table 10 outlines the mean indirect tensile modulus limits for each asphalt type

Moisture Sensitivity

Wet Tensile Strength and Tensile Strength Ratio must comply with the requirements of Table 11
Table 11 outlines the minimum wet tensile strength and minimum wet to dry tensile strength ratio for each asphalt type

Resistance to Deformation

Maximum tracking depth tested under the AGPT/T231 Deformation Resistance of Asphalt Mixtures By The Wheel Tracking Test must not exceed the values specified in Table 12
Table 12 outlines the maximum tracking depth for each asphalt type

Resistance to Fatigue under Flexural Bending

Fatigue testing requirements will be included in a future revision based on the outcomes of further investigations### Understanding Key Terms
The word "should" denotes a recommended but not mandatory requirement.
The word "includes" and similar expressions do not limit what else may be included.
