The company will provide drystone, ready-mixed concrete and asphalt for the £35m first project stage between Kincraig and Dalraddy south of Aviemore.
The £3bn scheme aims to transform 80 miles of single carriageway between Inverness and Perth by 2025.
The five-mile stretch between Kincraig and Dalraddy is being carried out by the Wills Bros John Paul joint venture (JV) and involves developing five new structures, numerous side roads and accesses to local estates.

It is understood Breedon is erecting a new high capacity concrete plant and a Benninghoven mobile asphalt plant at its quarry near Kingussie to service the contract.
The company will supply substantial quantities of drystone along with around 25,000m3 of concrete as well as 100,000 tonnes of asphalt.
Alan Mackenzie, Breedon Scotland's chief executive, said: "This contract underpins our order book for the current year and secures a significant amount of work for our Meadowside quarry over the next 12-18 months.
"The A9 is the main route between north and south Scotland, but has been hampered for many years by long stretches of single carriageway. We're delighted to be playing our part in reducing future journey times on this critical artery and making it a much safer road to drive on in years to come."
