The 2015 edition of the Pavement Recycling and Stabilisation Guide includes Section 12 on pavement construction.
Quicklime may be recommended by the designer or the contractor, for a variety of reasons - as a lighter weight product it has many benefits.
Binder spreading is vital to the success of the pavement construction. It is important during the construction process to restrict the movement of construction traffic on the pavement, until the binder has been mixed into the pavement.
The maximum application rate for quicklime binder is 15 kg/m2 to ensure complete hydration before mixing.
Slaking is undertaken after spreading the quicklime by surface spraying the binder with water to convert the quicklime to hydrated lime. Additional water can be added to achieve optimum moisture content for the required compaction.
The Guide can be ordered here. For more information about the difference between quicklime and hydrated lime, click here.
The 2016 face to face training program has been released. The course has been retitled Pavement Recycling and Stabilisation. In 2016 the course presenters will include Bob Andrews, Phil Walter and others for CPEE, Leah Fisher and Greg White for AustStab, as well as Daniel Orriss, Scott Young, Kerry Constanti and others representing the contracting members. Enquiries for all courses are welcome.
Early bird rates will apply up to four weeks prior to all courses this year. The early bird rate provides a saving of up to 15% for delegates. Group discounts are also available for groups of 4 or more delegates.
This year we will seek to engage with consultants and civil contractors to participate in the course, as well as our usual markets of local and state government and contracting members.
We also are pleased to announce that James Loney, Durkin Constructions is the inaugural winner of the AustStab sponsored CPEE Student Excellence Award for 2015. We will present James' award to him this week.
