3. Site Progress Report by Individual Site (from Exception Report)
RS664 ch564-1301 This treatment length is a programmed 16/17 reseal but is not yet completed and requires
pre-seal repairs which have also not been undertaken. The pre-reseal crew and the sealing
crew are now currently both mobilised in the area. This length will be sealed within the next
few weeks following completion of the pre-seal repairs.
RS664 ch1430-1944 This treatment length is a programmed 16/17 overlay which was completed in January 2017.
RS664 ch1944-3450 Programmed for treatment in 18/19 but various pavement repair dig-outs programmed for
completion this year following the pre-seal repairs on the 16/17 sealing programme. All
exceptions are Priority B from the latest survey.
RS664 ch3779-3993 This treatment length is a programmed 16/17 reseal but is not yet completed but this length
has no pre-seal repairs and is therefore programmed for immediate treatment. The sealing
crew are now currently mobilised and this site will be the first to be completed, hopefully
this week weather permitting.
RS664 ch4000-4580 This length covers a 15/16 Ohakuri seal that stripped and was repaired but now requires
under the Official Information Act 1982
more watercutting. The majority of the exceptions are priority B but there are 3 which trigger
the Priority A flushing criteria. This is a Downer risk site that will be addressed as part of the
current watercutting programme. Not yet completed.
RS664 ch4760-4970 This site is a programmed 17/18 AWT with the problem confined to the right hand
(decreasing) lane. Following the site visit the agreed treatment to address the safety issue

through the coming winter until the 17/18 AWT will be to seal the right hand lane with a
G2/4 reseal using Waotu aggregate.
RS664 ch8360-8380 This site is a programmed 20/21 reseal with the problem confined to a short length of the
right hand (decreasing) lane. Following the site visit the agreed treatment is to carry out a
short maintenance combi-seal to the right hand lane.
RS664 ch8460-8620 This site is a programmed 21/22 AWT and was identified as a potential additional seal for
this year. Following the site visit the agreed treatment is to carry out a 2 coat seal to the left
hand (increasing) direction in the nearside wheelpath.
RS664 ch9085-10018 This treatment length is a programmed 16/17 reseal but this length also has pre-seal
repairs which are not complete. The pre-seal crew are mobilised and have commenced the
repairs so following completion this will be sealed within the next couple of weeks.
RS664 ch10018-10580 This treatment length is a programmed 17/18 reseal but this length has been brought
forward following the RAPT and will be funded in 16/17 under asset preservation. The
length requires some pre-seal repairs which will be carried out under the current
programme on site. The agreed treatment following the site visit is to use a G2/4 with a
combination of Waioeka (G2) and Glenbrook (G4) providing the Glenbrook is available.
Downer are to advise of current availability and if none in stock what additional tonnage
would be needed. The work is to be programmed as part of the reseal works currently
underway.
RS664 ch10580-10700 This is a programmed overlay for 17/18 and although this length was not highlighted on the
exception report it was agreed during the site visit to add to the list of watercutting to
address the “fatty” v sual areas on the seal around the curve.
RS664 ch10700-10980
under the Official Information Act 1982
This is also part of the programmed overlay for 17/18 and identified for a “hot chip”
remedial treatment to deal with excessive binder present in isolated areas prior to the
programmed work next season. The treatment was agreed as an appropriate response
during the site visit.
