Project details
Description
The works are required to maintain the safety and integrity of the A9 carriageway between Westerton and Aberuthven, Perth and Kinross. This section of carriageway is currently exhibiting various areas of cracking, crazing and potholes, as well as wear and tear of road markings, missing road studs, channels and edgings.
The works will include resurfacing the carriageway using TS2010 surface course with depths varying from 40mm to 100mm depending on the condition along the length of the scheme.
The proposed construction activities for resurfacing will involve the following:
- Milling of existing bituminous material by road planer;
- Hand-held jackhammer and compressor for breaking up surfaces not accessible by planer;
- Loader/excavator used to collect and move excess material;
- Base/binder material laid and compressed (where required);
- New bituminous material laid by a paver;
- Material compacted using a heavy roller;
- Mechanical sweeper to collect loose material;
- Heavy Goods Vehicle (HGV) for removal and replacement of material; and
- Road markings replaced using an extrusion tool.
Materials required for works are:
- TS2010 surface course;
- AC32 base;
- AC20 binder;
- Bitumen;
- Road paint; and
- Road studs.
The total area of works is approximately 14,000m2 (1.4ha) across the northbound side of the carriageway.
The proposed works are programmed to be completed within the next financial year (from April 2025) over a duration of 10 days, with overnight working required.
Traffic Management (TM) to be utilised in the form of night-time contraflow.
Location
The works are located on the A9 carriageway between Westerton to Aberuthven, Perth and Kinross, over a length of 2.1km with an approximate area of 14,000m2. The National Grid References (NGRs) for the scheme are provided below and illustrated in Figure 1:
