Austroads reveals new pavement measures and specifications

Austroads has unveiled new measures and testing methods for paving in Australia.  

The new measures include technical specifications for the supply of pavement materials and the application of road surface treatments, as well as new and updated test methods for the design, production and placement of asphalt and spray seal pavements. 

New technical specifications ATS 3125ATS 3130 and ATS 3135 outline the requirements for the supply of fillers, coarse and fine aggregate, and reclaimed asphalt pavement material used in the manufacture of asphalt. 

Technical specifications ATS 3465 and ATS 3466 focus on supplying and applying coloured and high-friction pavement surface treatments.  

It comes after the industry body released a new set of construction specifications.

Test methods 

The technical specifications reference a new test method, ATM 058, and updated test methods, ATM 191ATM 192 and ATM 250. 

ATM 058 was developed to assess aggregate shape as a ratio of Average Greatest Dimension to Average Least Dimension. 

ATM 191, ATM 192 and ATM 250 set out procedures for extracting bituminous binders from bituminous mixtures, determining the viscosity of binders recovered from RAP source materials, and determining the surface texture depth of road surfaces by the sand patch technique.
